Comstock

The scoring method is called comstock, named after its inventor Walt Comstock, which means that the competitor has unlimited time to complete the stage and can fire an unlimited number of rounds.^[7] The time is measured from the start signal until the last shot fired using special shot timers with microphones, and this way the competitor can influence the total stage time. Since the number of rounds is unlimited, the competitor can re-engage the same target to get more points, but at the cost of using more time. Usually, the two best scoring hits count for each target.

Competitors are ranked for each stage by their hit factor, which is the ratio of points per second. The hit factor is calculated by summing the points (target scores minus penalties) and dividing by the time used.

${\displaystyle hit\ factor={points \over seconds}}$

For example, if a stage has 12 paper targets, requires two scoring hits per paper target, and since an A-hit gives 5 points, the stage will have 12 × 2 × 5 = 120 points available. If a competitor scores 115 points and uses 25.00 seconds he will get a hit factor for that stage of 115 points⁄25.00 s = 4.6. The competitor with the highest hit factor wins the stage and gets all the available stage points (in this case 120 stage points), while other competitors are given stage points based on their hit factor percentage compared to the winner. For the overall match score, stage points are added for all stages, which means that each stage is weighted by how many stage points that are available.

The scoring method allows for a precise gradation of performances across the match, but requires a computer and software to do in a timely fashion. Matches can either be scored on paper and manually transferred to the official IPSC Match Scoring System (WinMSS), or can be scored directly on electronic devices like smartphones and tablets with the WinMSS Electronic Score Sheet (ESS) app or third party scoring systems like Shoot'n Score It or PractiScore.

Power factor

The power factor is the momentum of the fired bullet as it's moving through the air, which contribute to the recoil of the firearm (together with the propellant gases stemming from the amount of gunpowder). Thus, the power factor in a way reflects recoil. The power factor must exceed certain thresholds, and is calculated by measuring the bullet speed using a chronograph and measuring another of the competitor's bullets on a weighing scale to find the bullet mass, thereafter calculating the power factor by the formula:

${\displaystyle {power\;factor}={mass}\cdot {velocity}}$

The official unit used for the power factor is the imperial unit "kilo grain feet per second" (kgr·ft/s), while newton-seconds (Ns) would be the metric equivalent. "Grain feet per second" (gr·ft/s) can be obtained by measuring the mass in grain (gr) (equal to 1⁄7000 pound), and velocity in feet per second (ft/s), but since their product yields a very large number it is common to multiply by a factor of 1⁄1000, obtaining the power factor in "kilo grain feet per second" instead.

${\displaystyle kgr\cdot ft/s={\frac {grain\cdot ft/s}{1000}}}$

To measure the muzzle velocity the competitor's ammunition must be fired in the competitor's firearm, since velocities can vary slightly from one firearm to another. In for instance handgun competitions, the ammunition must exceed 125 kgr·ft/s ((2.47 Ns)) for minor scoring, and at least 160 or 170 kgr·ft/s (3.16 or 3.36 Ns) for major scoring (depending on division). Extra scoring is not given for exceeding the threshold. A competitor declaring major, but who fails the threshold, have their score re-calculated at minor. A competitor who fails the threshold of minor is given a score of zero for the match.

Targets

The IPSC paper target which is used in all disciplines.

Poppers are used as falling steel targets.
Left: Drawing of a full size IPSC Popper (85 cm).
Right: A ⅔ scaled down IPSC Mini Popper (56 cm) used to simulate greater distance.

To achieve a varied, challenging and exciting sport there are no fixed target arrangements, distances or shooting programs, making every match unique. Paper and steel targets can be mixed in the same stage, and may be static, moving or partially covered by targets called no-shoots that give minus points if hit.

Paper targets have the three scoring zones A, C, and D with points per hit varying slightly depending on power factor. A center hit for both minor or major is five points, but hits in lesser scoring areas are rewarded more for major than minor with the A-C-D zones being scored 5–4–2 for major and 5–3–1 for minor (see table below). A competitor who has declared minor must therefore either shoot more "A" hits or shoot faster than one who has declared major to make up the scoring disadvantage.

Some typical examples of moving target setups are swingers, bobbers, clamshells, movers, and drop turners.

Scoring of the targets is done by the Range Officer. For the competitor to get the relevant scoring value or penalty points, the bullet hole must at least touch the line of the scoring area.^[8] (Breaking the relevant scoring line is thus not necessary.)

Steel targets score 5 points and must fall to be scored. (For rifle some steel targets may score 10 points).

For paper targets, the octagonal IPSC Target in typical cardboard color is used throughout all the disciplines, and a ⅔ scaled-down IPSC Mini Target is used to simulate a full size target placed at a greater distance. Additionally, the Universal Target can be used for rifle or shotgun, while the A3 and A4 paper targets are approved for shotgun matches only.

For steel targets, there are two standardized knock down targets, the IPSC Popper (85 cm tall) and the ⅔ scaled-down IPSC Mini Popper (56 cm tall). Metal plates are often circles between 20–30 cm in diameter or squares between 15×15 cm to 30×30 cm for handgun, and circles between 15–30 cm in diameter or squares between 15×15 cm to 30×45 cm for rifle and shotgun.

Handgun

Example of handguns for different divisions, Open on the left and Standard on the right.

In handgun, there is currently one division for optical sights and four divisions for iron sights. The minimum caliber is 9×19 mm for all handgun divisions. During the competition the handgun must be worn in a holster securely attached to the competitor's belt. The holster needs to cover the trigger guard, the heel of the gun needs to be above the top of the belt and the belt has to be attached through at least three belt loops. Men must wear the holster, magazine holders, etc. in the belt at waist level, while female competitors may choose to wear their equipment either at hip or waist level. During the competition the position of the holster, magazine holders etc. can not be moved or adjusted from stage to stage. For all divisions except Open and Revolver the foremost portion of the handgun and all magazines must be placed behind the hip bone. Race holsters are permitted in all divisions.

Open

The Open division is the handgun equivalent to the Formula 1 race car where most modifications are permitted to achieve a faster and more accurate gun. It's the only division which permits optical and electronic sights (such as red dot sights) and recoil reducing muzzle brakes (also called compensators).^[9] The division facilitates the highest magazine capacity, placing a restriction of 170 mm maximum overall length measured at the rear of any magazine. Shorter magazines, i.e. 140 mm, are also popular because of easier handling and often more reliable feeding, leaving the competitor a choice of equipment according to the stage at hand.

Open and Revolver are the only two divisions where 9 mm bullets (.355") can be used to achieve major scoring, and hence .38 Super (or some variant) or 9×19 mm loaded to major power factor of 160 kgr·ft/s are popular cartridges for the pistols in Open. The 9 mm caliber cartridges provides higher gas pressures and better magazine capacity over 10 mm calibers. Open handguns are often expensive custom builds with parts and features specifically designed for competition, and with the maximum magazine length of 170 mm some 9 mm/ .38 Super magazines can hold up to 28 or 29 rounds.^[10][11]

The Open division was formally adopted at the General Assembly following the 1992 European Handgun Championship in Barcelona, Spain, and became a recognized division starting in 1993.^[12] Any handguns complying with the previous rules were included, for instance, there was no restriction placed on handgun size or type of sights. Later the 170 mm maximum length was introduced.

Standard

Standard division allows any handgun that fits inside the IPSC box, and most modifications are permitted (except optical sights or compensators). Light match triggers are common, and modifications such as slide rackers, thumb rests ("gas pedals") and grip tape on the slide can sometimes also be seen. The IPSC box has internal dimensions of 225 x 150 x 45 mm^[9] in length × height × depth with a tolerance of +1 mm, −0 mm (approximately 8.86 × 5.91 × 1.77 inches). The handgun must fit with the slide parallel to the longest side of the box and hammer cocked if applicable. The handgun must fit the box with any of its magazines inserted, which means that for instance on 2011 pattern pistols either 124 or 126 mm magazines usually will give the maximum capacity and still fit the box.

Minimum caliber for minor scoring is 9x19 mm loaded to a power factor of 125 kgr·ft/s while minimum caliber for major scoring is a 10 mm (.40") cartridge loaded to a power factor of 170 kgr·ft/s, making for an interesting choice between minor and major scoring taken in mind the differences in recoil, magazine capacity and scoring points. An example of differences in magazine capacity depending on caliber can be seen when comparing stock 126 mm STI 2011 double-stack magazines, which according to the manufacturer yields a capacity of either 12 rounds for .45 ACP, 14 rounds for .40 S&W or 17 rounds for 9x19 mm.^[13] Magazine capacity can be further increased using aftermarket springs, followers and basepads as long as they still fit the box. For a 2011 pattern handgun, aftermarket parts and magazine tuning can increase capacity from 12 to 16 rounds for .45 ACP, from 14 to 19 rounds for .40 S&W and from 17 to 21 rounds for 9×x19 mm. It is a common belief that major scoring using the .40 S&W will give better scores for most competitors over the 9x19 mm, but at the cost of more expensive ammunition.

The Standard division was formally adopted at the General Assembly following the 1992 European Handgun Championship in Barcelona, Spain, and became a recognized division starting in 1993.^[12] One of the intentions of the Standard division was to create a division for more "stock" firearms, which up until then had been no equipment divisions, and the sport had started to become dominated by custom-built race guns with compensators and optical sights. However, the Standard division was later criticized for also having become a "race division" somewhat like the Open division, which was dominated by custom built guns and specialized gear. Major caliber .40 S&W dominates, since it is seen as a much better alternative scoring-wise, but is more expensive than regular minor scoring 9×19 mm (price difference varies, but usually 50–60% more expensive). Also, from a practical standpoint, the .40 S&W round can be difficult to obtain when travelling to international matches, while the 9x19 mm round, on the contrary, is perceived as affordable and available all around the world. This made way for the Production division starting in 2000, which has minor scoring only, allows fewer modifications and has a common magazine limit of 15 rounds.

Production

The Production division is the most popular division as of 2016. The division allows very few modifications and is limited to typical "off the shelf" service pistols which has to be explicitly approved and listed on the IPSC Production Division List. Maximum barrel length is 127 mm (5 inches). The handgun must be double-action (DA/ SA, DAO or striker fired), and is required to have a minimum trigger pull weight. Striker fired handguns have a minimum trigger pull of 1.36 kg for every trigger pull, while DA/SA handguns are required to have a minimum trigger pull of 2.27 kg only for the first double action trigger pull (no weight limit for subsequent single action trigger pulls).

Production is the only division with minor scoring only, which means that anyone can be competitive with affordable and readily available 9x19 mm factory ammunition, without having to worry about handloading to provide significant savings. Together with (in general) affordable handguns, Production, therefore, makes for a popular division. Different models of handguns have variance in magazine capacity, but this is evened out by limiting competitors to load their magazines to a maximum of 15 rounds (15 in each magazine plus 1 in the chamber).

Permitted modifications are limited to the application of grip tape in limited areas around the grip, replacement of sights that do not require gunsmithing to be installed (i.e. milling to the slide) and the replacement of internal components only available as a factory option from the original manufacturer. After-market magazines are allowed. Minor polishing and fitting of trigger components is permitted. Note that there are differences in approved handguns for the IPSC Production division and the USPSA Production division, as well as permitted modifications.

From 2019, the Production division has been divided into Production, Production Optics and Production Optics Lite. Production Optics is based on the Production rules, but with an optical sight mandated. The optical sight can only be mounted to the un-modified slide. Racking handles or other protuberances from the optical sight or its mounting is not permitted. Production Optics Lite is similar, except that the complete handgun must satisfy a weight limit of 1000 grams

The Production division was introduced at the General Assembly after the 1999 Handgun World Shoot in Cebu, Philippines,^[14] and became a recognized division starting in 2000. Production Optics was accepted as a trial division in 2017,^[15] and both Production Optics and Production Optics Lite were definitively accepted in 2018.

Classic

Introduced in 2011, the Classic division was modelled after the USPSA Single Stack division and is limited to handguns visually resembling the single stack 1911 form. The handgun with any of its magazines inserted has to fit inside the IPSC box. The competitor can choose between maximum 8 rounds per magazine for major scoring or 10 rounds per magazine for minor scoring. Minor scoring can be achieved with a 9 mm projectile loaded to a power factor of 125 kgr·ft/s, while major scoring requires a 10 mm or larger projectile loaded to a power factor of 170 kgr·ft/s.^[9]

Handguns must have a one-piece metal frame, slide with stirrup cuts and the dust cover (with or without an accessory rail) can have a maximum length of 75 mm from the leading edge to the rear of the slide stop pin. Magazine wells cannot exceed a maximum outside width of 35 mm. Permitted modifications are shaped slides (i.e. flat-top or tri-top), shaped trigger guards (i.e. squared or undercut), bob-tail backstraps, bull or coned barrels, external extractors, finger-grooves (machined, add-on, wrap-around, etc.), custom magazine release buttons, triggers, hammers, single/ ambidextrous thumb safeties, any iron sights, extended slide lock levers and thumb shields provided they do not act as a thumb rest. Cosmetic modifications are permitted.

Prohibited modifications / parts are slide lightening cuts, weak hand thumb rests and slide rackers.

Revolver

In the Revolver division double action revolvers in caliber 9x19 mm or larger of any capacity can be used. Muzzle brakes or optical sights are not permitted. Competitors may declare major with a 9 mm (.355") bullet loaded to a power factor of 170,^[9] but a maximum of 6 rounds can be fired before a reload is required. From 2017, there is no limit on the number of rounds fired before a reload is required, but revolvers with a capacity of 7 rounds or more will automatically be scored as Minor power factor. It is common to use moon clips for faster reloads. The Revolver division was introduced at the General Assembly after the 1999 Handgun World Shoot in Cebu, Philippines, and was a recognized division starting in 2000, initially under the name "Revolver Standard" before it was renamed to "Revolver" around 2009.

Modified

Now obsolete, the Modified division was a mix between Open and Standard. Handguns were allowed to have compensators and optical sights as long as they would fit in the IPSC box with any of its magazine inserted. The Modified division was formally adopted at the General Assembly following the 1992 European Handgun Championship in Barcelona, Spain, and became a recognized division starting in 1993.^[12] The division saw some use in southern Europe, but was otherwise not very widespread, and was retired after the 2011 World Shoot XVI in Rhodes, Greece. Competitors with Modified handguns would then afterwards compete in Open.

Rifle

Important elements in rifle include the use of prone, off hand and supported shooting positions. Starting position is usually with the butt of the rifle touching the hip. Knowledge of the firearms ballistics is a key element to succeed at the long range targets.^[16] The recommended balance of target distances is that 30 percent of the targets are placed closer than 60 meters, 50 percent of the targets between 60 and 150 meters and 20 percent of the targets between 150 and 300 meters. Most competitors zero their sights at 200 meters. Being an outdoor sport, the weather can have a profound effect on competitor scores due to wind or different lighting conditions, especially on long range targets. Therefore, top-ranked competitors are often squadded together to achieve the most similar conditions.

There is no minimum caliber, but the ammunition has to make a power factor of 150 kgr·ft/s for minor or 320 kgr·ft/s for major scoring (formerly 160 and 340 kgr·ft/s respectively).^[17][18] Since two hits per target is normally required, rifles with minor power factor calibers dominate on the shorter ranges in most of the divisions due to less recoil and shorter recoil impulse. Minor ammunition being most common means that anyone can be competitive with affordable and readily available .223 Remington factory ammunition, without having to worry about handloading to make major. Ammunition loaded to major power factor has more recoil and a longer recoil impulse, but have the advantage of better ballistics at long range targets. Major scoring may be more competitive in the manual divisions since normally only one hit is required per target, lessening the importance of a small recoil impulse.

In the beginning, competitions were fired with whatever rifle the competitors chose, and while the type of rifles mostly has remained the same sighting systems have changed a lot. In 1990, Sverre Idland won the Norwegian rifle championship using an Elbit Falcon red dot sight. Low-power scope sights have been used in competitions since at least 1994, when Bengt Larsson used a Schmidt & Bender 1.1–4x20 mm to win the Norwegian Championship.^[19] For a while rifles equipped with optics and iron sights competed side by side, but were divided somewhere around the 2000s into an Open division for optic sights and a Standard division for iron sights. Open and Standard were the only two rifle divisions until the 2004 season when similar divisions were introduced for manually operated mechanisms. The Open and Standard division was then renamed to Semi Auto Open and Semi Auto Standard, while the new manual divisions was named Manual Action Open and Manual Action Standard. Around 2011 a provisional division named "Manual Action Standard 10" was approved for evaluation as a testing ground for development of the Manual divisions.

Self-loading rifles are used in the Semi Auto Open and Semi Auto Standard division, while the manual divisions are limited to manual action types.

Semi Auto Open (Open)

Semi Auto Open, usually simply referred to as the "Open division", is the most popular rifle division. Optical sights are allowed together with bipods and muzzle brakes.^[20] Bipods can be taken on and off during a stage, and on some stages, it can even be advantageous to switch between different bipod sizes. Many top competitors use rifles with 46 cm (18-inch) barrels to run the longer rifle length gas system and achieve a softer recoil impulse. An adjustable gas system is popular. Some also use low-mass bolt carriers and buffer weights, which may, however, cause reliability issues if not tuned correctly.

Low-power scope sights with a variable magnification starting at 1x (called low-power variable optics, or LPVOs) are popular, with magnifications of 1–6x or 1–8x and daytime bright illuminated reticles are the most popular. Usually, only the center of the reticle is illuminated. Some reticles have milliradian-based wind holds or holdover marks to compensate for wind and bullet drop on long-range targets, while others prefer reticles with a simple dot and crosshair and choose to dial long-range adjustments on the turrets instead.^[21] Turrets are often exposed and lockable, having ballistic drop compensation (BDC) and a zero stop, while some competitors choose to use capped turrets for the wind adjustment. Important optical characteristics^[22] are true 1x or 1.1x low-end magnification, while on higher magnification it is important with a large field of view and a large exit pupil. Some other important scope qualities are weight and stray light performance.

To avoid having to adjust magnification up and down when transitioning between several long and short-range targets during the same stage, some combine a scope with a 45-degree side-mounted red dot optic, but the effectiveness of this is debated, and there are both top competitors who use it and not. For instance, Raine Peltokoski uses only one optical sight, and in such situations instead uses a technique called "Occluded Eye Aiming", where one blocks the objective (i.e. with a lens cover or by hand) so that one only sees the illuminated dot with one eye and the target with the other eye.^[23]

Rifles with non-magnified red dot sights as the primary optic also compete in Open and are very competitive at short ranges, but the lack of magnification is a big disadvantage at longer ranges.

Semi Auto Standard (Standard)

Table of different front sight post sizes in mil and at what distances the full width of a target would be covered. A sight post that appears wider than the target can make precise aiming difficult, but this can be solved by adjusting the sights up and aiming below the target.

The Semi Auto Standard division usually simply referred to as the "Standard division", tests the added skill of using iron sights only. Also, bipods are not allowed and muzzle brakes have to be within the maximum dimensions of 30x90 mm (approx. 1x3.5 inches).^[20] A long sight radius is desirable as it helps even target and sight focus due to larger depth of field, and thus iron-sighted rifles often have longer barrels with the front sight attached to the end of it. Many Standard top competitors use the longer 50 cm (20") barrel over the 46 cm (18") to achieve longer sight radius. Any iron sights can be used, and both "globe" and "post" front sights are popular, as well as aperture, ghost ring or diopter rear sights.

Manual Action Open (Manual Open)

The manual divisions test the added skill of using a manual action, meaning that the rifles must be operated by physical manipulation, with some examples being bolt, pump or straight pull actions. Manual Action Open, usually simply referred to as the "Manual Open division", allows optical sights, muzzle brakes and bipods.^[20] Turn bolt actions require the competitor to perform both rotational and linear motions during the loading cycle, while pump- and straight-pull actions can be cycled back and forward without rotation of the bolt handle by the competitor. This reduces the number of movements from four to two, but comes at the cost of often having either poor or no primary extraction.^[24][25] increasing the risk of malfunctions. A turn bolt action on the other hand has a mechanical advantage used during chambering and primary extraction, which makes for more reliable feeding and extraction. Both types of mechanisms have won championships. Bolt action rifles usually also have a much shorter lock time than hammer fired pump and straight-pull actions, which can play a significant role in accuracy on long-range targets.

Manual Action Standard (Manual Standard)

Manual Action Standard, usually simply referred to as the "Manual Standard division", is limited to iron sights only, and no muzzle brakes or bipods are allowed.^[20] Manual Action Standard 10 (MAS10) (between 2012 and 2017) was a trial division that allowed iron sights only, a magazine capacity of 11 rounds (10 in the magazine plus 1 in the chamber) and factory-fitted muzzle brakes only.^[20]

• 
  Long guns (rifles and shotguns) must have a brightly colored chamber flag inserted when the firearm is not in use.
• 
  Rifles fitted with optics and bipods compete in the Open division.
• 
  In the Standard divisions only iron sights are allowed, and bipods are not permitted.
• 
  In the Manual divisions, rifles must be operated by physical manipulation. Examples are bolt (pictured above), pump- or straight-pull action.

Shotgun

Daniel Horner firing his shotgun at a flying clay target during a match in South Carolina, US in 2017.

Starting position is usually with the shotgun in one hand and the butt of the shotgun touching the hip. There is only one power factor of 480 kgr·ft/s, and all targets are scored as major which means that anyone can be competitive with affordable and readily available 12 gauge 70 mm (2+3⁄4") ammunition. Different options on shotgun chokes^[26] and ammunition (from different pellet sizes and up to slugs) makes for interesting choke and ammunition choices based on the stage at hand where the competitor has to consider the spread of the choke relative to the distance. All divisions have limits of the number of shells loaded at the beginning of the stage, but the limits are removed after the start signal. For instance, some may choose to run 10 or 11 round tubes in the Standard division which is limited to 9 rounds in the tube at the start signal.

Open

The Open division allows optical sights, muzzle brakes, and is the only division that permits detachable magazines or the use of speed loaders for tube magazines. The maximum overall length of the shotgun is 1320 mm (approximately 52 in) measured parallel to the barrel.^[27] Detachable magazines must not contain more than 10 rounds at the start signal, while shotguns with fixed magazines may have an initial load of 14 rounds. After the start signal detachable magazines can be loaded up 12 rounds, while there is no limit for tube magazines.

Modified

The Modified division allows muzzle brakes and optical sights, but is limited to internal tube magazines. The maximum overall length of the shotgun is 1320 mm.^[27] Modifications of the floor plate to facilitate loading is permitted, given that the modification doesn't exceed 75 mm in length or protrudes more than 32 mm from the shotgun frame in any direction. Maximum 14 rounds can be loaded at the start signal (13+1, 13 in the tube plus 1 in the chamber), but more can be loaded after the start signal. Until 2017 the division was limited to iron sights, but from 2018 optical sights are permitted.^[28][29]

Standard

The standard division is the most popular division as of 2017.^[30] The division is limited to iron sights and internal tube magazines, and muzzle brakes are not allowed. The shotgun model has to be factory produced of at least 500 units.^[27] Maximum 9 rounds can be loaded at the start signal (8+1, 8 in the tube plus 1 in the chamber), but more can be loaded after the start signal.

Standard Manual (Manual)

The Standard Manual division, usually simply referred to as the "Manual division", is the only shotgun division limited to manual actions. Limited to iron sights, internal tube magazines, and no muzzle brakes, the shotgun model has to be factory produced of at least 500 units.^[27] Maximum 9 rounds can be loaded at the start signal (8+1, 8 in the tube plus 1 in the chamber), but more can be loaded after the start signal.

Other

• Tournaments are 2 or 3-Gun matches which can include any combination of the three disciplines handgun, rifle and shotgun in the same match. There are default Grand Tournament divisions, but match organizers may also declare their own specific Grand Tournament divisions. In addition to the main disciplines (handgun, rifle and shotgun) there are also some supplemental disciplines:
• Mini-Rifle is for small caliber rifles (.22 LR only) with minor power factor scoring only, and competitions are mostly held indoors in the winter as training in the off-season.
• Pistol Caliber Carbine (PCC) is for pistol caliber rifles only (9×19 mm, .40 S&W, .45 ACP, etc.,) with minor power factor scoring only. The Carbine division can be held up to level 3, and either as a standalone match or as a separate division in a regular Handgun, Rifle or Mini Rifle matches.
• Action Air is for airsoft handguns, and enjoys popularity in countries where civilian ownership of firearms are restricted. Minor power factor scoring only. Action Air is also used in the off-season in other countries as an affordable and easily available training tool because there is no need for a shooting range (competitions can, for instance, be held at an ordinary gym)

Types of courses

Walls and Fault Lines on the ground are used to define the boundary of the shooting area used during the Course of Fire.

A match consists of a mix between short courses (lowest number of targets), medium and long courses (highest number of targets). The approved balance for a match is a ratio of 3 short courses to 2 medium courses and 1 long course (i.e. 6 short, 4 medium and 2 long courses for a level 3 match). Since the number of targets dictates the available points for that stage, and therefore Long courses potentially can have a have great impact on the overall standings. Short courses have fewer points available, and tend not to be as critical for the overall standings. Short courses are often more technical, offer many different stage solutions, or include challenging elements such as "empty chamber" or "empty magazine well" starts, or "non-freestyle shooting" elements such as strong or weak hand only. Medium courses are something in between, while long courses will have the highest round count. Long courses tend to be more freestyle and straightforward as far as different stage solutions. The shooting challenges may still not necessarily be easy, and a match can be lost or won at a long course since there are so many points available.

Match levels

The opening ceremony at the 2017 IPSC Rifle World Shoot in Russia.

Competitions are held at all levels from club matches and up to the world championships.^[31] Level 3 matches and up require official IPSC pre-approved match level sanctioning in regards to courses, IROA-range official, etc.

• Level 1: Club matches
• Level 2: Matches open to participants from different clubs
• Level 3: Regional matches, i.e. national championships or other large matches such as the Extreme Euro Open
• Level 4: Continental championships, i.e. the European or Pan-American Championship
• Level 5: The World Shoots

The World Shoots are the highest level shooting matches within IPSC. Held since 1975,^[32] it is a multi-day match where the best IPSC shooters from around the world compete for the World Champion title.

Match etiquette

Walkthrough refers to being inside the fault lines of a stage when not shooting, and is usually done by competitors for finalizing stage plans. Walkthroughs are restricted for equity reasons. Competitors are not allowed to enter or walk on the stages on their own initiative, but must be invited to do so by the Range Officer first after having received the stage briefing. After the stage brief, the squad as a whole is normally given between 3 and 5 minutes to walk the particular stage collectively. Afterwards, the command Time's up is given, upon which the first shooter is asked to load and make ready.

On-deck refers to the competitor first in line waiting to shoot. The shooter second in line is referred to as being in-the-hole. During scoring of the preceding shooter, the shooter on deck is usually allowed to take a final walkthrough.

So as not to disturb, spectators and other competitors should be still and remain silent while a competitor is preparing to shoot as well as during shooting.

After a competitor has performed well on a stage it is common to receive soft applause. Such quiet clapping is the preferred form of applause for shooters; louder forms of applause are discouraged so as not to disturb other shooters who may be in the process of attempting a stage. Shoot-Off's are an exception to this.

After having completed a stage and received scores it is common for the competitor to thank and shake hands with the Range Officer.

Competitors are divided into Squads that rotate between the Courses of Fire. A Super Squad refers to a Squad of elite and top-seeded competitors who are among the favorites to win a match. They often consist of two or more national teams who are handpicked by their respective national sport directors. Match favorites are required to be placed in Super Squads so that they get the most similar conditions.

Shoot-Off

A Shoot-Off is an audience-friendly duel shooting organized as a knock-out tournament where the shooters compete 1-on-1 and the winners advance further towards finals. It is usually held at major events after the main-match, and the best shooters from the main-match are eligible to participate. It is often shot at falling targets such as poppers, and to win a shooter must knock down all their falling targets and reach their stop target before the other competitor. Dependent on schedule, quarter, semi, bronze and gold finals may be held.

Shoot-Offs can be decided by small margins. At the 2018 Shotgun World Shoot, U.S. shooter Scott Greene and Russian Roman Anikin both fired their last shots almost simultaneously, but Greene had chosen a more constricted barrel choke. This gave a tighter shot pattern and a greater risk of missing, but ultimately lead to his target falling faster to win the Shoot-Off.

Match officials

The International Range Officers Association (IROA) is a part of IPSC with the responsibility to train and certify their own dedicated range officials, who are responsible for conducting matches safely, fair and according to the rules. In addition, each IPSC region have their own National Range Officers Institute (NROI) under the IROA. In a match range officials from IROA and NROI can work alongside in the ranks:

• Range Officer (RO) – The Range Officer gives the competitors stage briefings, issue range commands and follows the competitor through the conduction of the stage to monitor time, scores and safe firearms handling.
• Chief Range Officer (CRO) – In case there are several Range Officers, a Chief Range Officer will be assigned to have the primary authority over the particular course. Like the RO, the CRO will oversee fair and consistent application of the rules.
• Range Master (RM) – The Range Master has the overall authority over the entire range during the match, including all Match Officials and the overall safety.
• Match Director (MD) handles the overall match administration before and during the match, including registration, squadding, scheduling, range construction and coordination of the staff. The Match Director doesn't have to be an NROI or IROA Official.
• Stats Officer (SO) is another important role with the responsibility to collect, sort and verify the final results.

Design of stages can be done with various tools such as pen and paper or digital software. There are also physical miniature models in 1:25 scale that can be used so that several persons can design and discuss stages and exercises by hand.

Coaches and instructors

The Main International Shooting Instructors Association (MISIA) is a part of IPSC with the responsibility to train and certify their own dedicated safety instructors and coaches,^[33][34] providing supervision and training for both team and individual players. Safety instructors conduct mandatory safety training programs, while coaches are involved in administration, athletic and shooting training, competition coaching as well as representation of practical shooting teams and players.
