Initial run (1993–1994)

The Smoking Gunns made their WWF debut on April 5, 1993 on the day after WrestleMania IX, defeating jobbers Barry Horowitz and Reno Riggins.^[4] Vignettes began airing on the WWF television promoting the debut of Smoking Gunns, beginning with the April 25 episode of Wrestling Challenge. Gunns made their televised debut in WWF on the May 15 episode of Mania as fan favorites by defeating Damian Demento and The Brookyln Brawler. During their televised debut, Brett Colt was renamed Bart Gunn and Kip Winchester was renamed Billy Gunn. Their first pay-per-view appearance was at the King of the Ring event in an eight-man tag team match, in which they teamed with Steiner Brothers to defeat The Headshrinkers and Money Incorporated when Billy pinned Ted DiBiase.^[5] Their next big match came at SummerSlam, when they teamed up with Tatanka to defeat Bam Bam Bigelow and The Headshrinkers.^[6]

From their debut until January 1994, they would fire blanks in the arena with real guns, but then they received complaints from families that they were scaring children, which caused them to stop firing guns in the arenas.

Although they continued to wrestle as a team, they did not appear together again on a WWF pay-per-view for over a year. In the fall of 1994, the Gunns began a feud with the Heavenly Bodies (Tom Prichard and Jimmy Del Ray). The Bodies attacked the Smoking Gunns and destroyed their cowboy hats. In return, the Gunns grabbed the Bodies' robes and tore off the wings.^[7] The teams had a series of matches at house shows,^[8] but the feud did not end with a blow off match. Instead, the teams faced off as part of a 5-on-5 elimination match at the 1994 Survivor Series. Billy and Bart became a part of Guts and Glory (Lex Luger, Mabel, and Adam Bomb) in a loss to Ted DiBiase's Million Dollar Team (King Kong Bundy, Tatanka, Bam Bam Bigelow, and The Heavenly Bodies).^[9]

Tag Team Champions (1995–1996)

The Gunns were scheduled to compete in a tournament for the vacant Tag Team Championship after Shawn Michaels and Diesel, the champions, began feuding. Injuries prevented the Gunns from entering, however.^[7] One day after their replacements, Bob "Spark Plug" Holly and the 1-2-3 Kid, won the belts, the Gunns returned to win the title on January 23, 1995 episode of Monday Night Raw.^[10][11] By 1995, Billy and Bart both shaved their mustaches and cut their long hair off. Gunns successfully defended the titles against Holly and Kid, The New Headshrinkers, Heavenly Bodies, and Men on a Mission. At WrestleMania XI, the Gunns faced Owen Hart and a mystery partner, who was revealed to be Yokozuna and lost the belts.^[12][13] Smokin' Gunns received a rematch for the titles against Owen Hart and Yokozuna at the inaugural In Your House event, but failed to win. Gunns would then briefly feud with The Blu Brothers, defeating them at SummerSlam.

On the September 25 episode of Raw, Gunns regained the Tag Team Championship from Hart and Yokozuna, beginning their second tag title reign.^[11][14] Gunns enjoyed a lengthy title reign, defeating challengers like Razor Ramon and 1-2-3 Kid at In Your House 4, and The Bodydonnas at the 1996 Royal Rumble. On February 15, 1996, the Smoking Gunns forfeited the titles when Billy was forced to undergo neck surgery.^[11][14]

Billy recovered quickly, the Gunns won their final championship three months later by defeating The Godwinns at In Your House 8: Beware of Dog.^[11][15] Following this victory, Sunny left the Godwinns to manage the Gunns later the team was called "Sunny and her Gunns".^[15] Sunny was a heel manager, which led to Gunns turning villains as they wrestled more aggressively, acting more arrogantly and teaming with other heels.

Sunny manipulated the Gunns, causing the brothers to argue. Sunny and Billy had an on-screen relationship, which bothered Bart.^[1] Meanwhile, Gunns continued their successful Tag Team Championship reign, defeating Godwinns in a rematch at King of the Ring. Gunns would then lose to Sunny's former clients Bodydonnas in a non-title match at In Your House 9: International Incident. At SummerSlam, Gunns successfully defended the titles against The Bodydonnas, The Godwinns and The New Rockers in a four-way elimination match. Gunns eventually lost the titles to Owen Hart and the British Bulldog in September 1996 at In Your House 10: Mind Games.

Split and feud (1996–1997)

Sunny left the team because she only wanted to be a manager for title holders (although she did not become Hart and Bulldog's manager).^[16] Billy, frustrated with losing both the title and Sunny, began having miscommunications with Bart. Gunns failed to regain the Tag Team Championship from Owen Hart and British Bulldog in a rematch at In Your House 11: Buried Alive. On the October 27 episode of Superstars, Billy eventually turned against Bart by walking out of a match against New Rockers. Bart, still managed to win the match. This led Gunns to implode and feud with each other.

Billy and Bart competed in opposing teams in a Survivor Series elimination match at the Survivor Series' Free for All. Following that, on the December 16 episode of Raw, the two competed in a match. During the match, Bart hit Billy with a botched hangman on the top rope that gave Billy a neck injury. It was then rumored that at WrestleMania 13, the Gunns were supposed to face against each other but the match did not happen. The two former partners had a decisive match on the June 9, 1997 episode of Raw is War, where Billy, who had changed his character to "Rockabilly", defeated Bart.
