is an action shooting sport similar to USPSA that involves the use of pistol, rifle, and shotgun often utilizing two or sometimes even all three firearms in each stage. A match is broken down into several stages where the shooter is scored based on his time to complete a course of fire consisting of cardboard silhouettes and steel targets. Time penalties are added to the shooter's time for misses and hitting non-threat targets. Stages consist of a 180 degree shooting environment ranging from 0 to 500 yards that often include multiple shooting positions, shooting around and through barricades, shooting while moving, unconventional shooting positions, moving targets, aerial shotgun targets, and hostage type non-threat targets. Stages are often free style which allow shooters to strategize their movement throughout the course in the most efficient manner. While safety rules are similar to USPSA, cardboard target scoring has been simplified requiring only a single A zone hit, a single head hit, or two hits anywhere on the target to neutralize it and avoid a time penalty. .308 caliber rifle hits only require a single hit on target to neutralize it.
Similar to USPSA, 3-Gun is broken down into different divisions that each have different equipment requirements. This allows a shooter to be competitive with almost any combination of firearms and does not require a large expenditure on equipment modifications to start competing. Below is a basic overview of each division. Please refer to the Match Rules for specifics.
.223 caliber rifle or larger
Iron sights or 1x optics – no magnified optics allowed
No bipods or muzzle supporting devices
Compensators must be 1” or less in diameter and 3” or less in length
No pistol optics or compensators
Pistol magazines must be 140mm or less for double stack and 170mm or less for single stack
Shotguns must be at least 20-gauge and may not have ports, compensators, or optics.
Shotguns may not be loaded with more than 8 rounds in the magazine at the beginning of a stage
Shotgun speed loaders (included detachable box magazines) are prohibited
Same as Limited, except a single optic may be used on the rifle (multiple optics not allowed).
Same as Tactical Optics, except the rifle must be .308 or larger.
World War 2:
Pistol must be a single stack 1911 in .45ACP with 8 round magazines
Rifle must be a M1 Garand in .30-06, SMLE in .303, or No 4 Lee Enfield in .303
Iron sights only
No bipods or supporting devices
No muzzle brakes
Shotgun must be a pump action 12-gauge with a maximum magazine capacity of 6 rounds
No shotgun speedloaders

9mm pistol or larger
No limitation on firearm accessories or modifications except the pistol magazines must be 170mm or less
2-Gun is similar to 3-Gun except stages consist of rifle and pistol use only, and the sport does not include the shotgun. 2-Gun is a direct spinoff of 3-Gun and was created to eliminate both the emphasis on shotgun reloading to the match score and the prohibitive cost of an autoloading shotgun and peripheral accessories. With the relatively high magazine capacity of pistols and rifles, 2-Gun allows the shooter to focus more on speed, accuracy, and strategy instead of weapon manipulations. The courses of fire are similar to 3-Gun excluding aerial targets, and the divisions are also the same excluding shotgun specific restrictions.
