Production Division is strictly limited to the use of production handguns with actions that are double-action-only, double-action/single-action or striker-fired – mostly in the caliber of 9mm. These are the “duty guns” available from nearly every pistol maker and each of the major manufacturers offers a wide variety of models that meet USPSA Production Division requirements. Stock revolvers may also be used, including the 7- and 8-shot variants. USPSA greatly restricts the level of modifications that can be performed on a Production gun.
While capacity is not uniform across model, caliber or manufacture, USPSA levels the playing field by limiting shooters to just 10 rounds per magazine. Regardless of the round used in Production, the division is scored as a minor power factor. Holsters and allied equipment must be “non-race-type” and be worn behind the forward most point of hip. Most shooters use a standard outside-the-waistband belted holster intended for daily wear, often made of kydex or plastic.
The Revolver Division is intended for stock revolvers and shooters are restricted to only six rounds between reloads. Modifications are limited and optical sights, porting and recoil compensators are prohibited. However, shooters may change grips, enlarge the cylinder release, change sights, chamfer cylinders and tune the action as they desire.
While .45 ACP is the most popular, shooters may score major using any cartridge that fires a .355 or larger bullet. Typically, competitors will use a "race" style holster in the Revolver Division.
Single Stack Division
The Single Stack 1911 Division caters to the traditional 1911 fan. USPSA introduced Single Stack as a provisional division in 2006 and made it a regular division in 2008. Only single-stack model 1911-pattern pistols are allowed in this division, and they must comply with a maximum weight limit, as well as fit fully within a box of specific dimensions. The equipment rules are similar to Production Division, other than providing for 8 rounds for major calibers and 10 rounds for minor. As for holsters, Single Stack shooters must adhere to guidelines similar to the Production Division, although unlike Production, dropped and offset holsters are not allowed. All equipment must be worn behind the hips and the holster must be a practical, non-race style such as those intended for daily wear.
Limited Division features both wide-body, or double-stack, 1911 pistols and single-stack 1911 pistols. Additionally, non-1911 pistols are also permitted. Modifications allowed to the gun include those for the Limited-10 Division, plus shooters may use high-capacity magazines so long as the magazine is does not have an overall length greater than 141.25mm for double-stack pistols and 171.25mm for single-stack pistols.
As with Limited-10, shooters must use a .400 caliber or larger bullet in order to score a major power factor.
The Limited-10 Division features both wide-body, or double-stack, 1911 pistols and single-stack 1911 pistols. Additionally, non-1911 pistols are also permitted. The name, Limited-10, is a reference to the total number of rounds (10) a competitor can load in his/her magazine. This capacity limitation eliminates any capacity advantage one model pistol would have over another. It was developed in response to the 1994 Crime Bill, which limited the capacity of newly made magazines to 10 rounds.
Competitors can make various minor modifications such as change sights, grips, slide stops, magazine releases and mainspring housings but optical sights, porting or a recoil compensator are strictly prohibited.
Calibers can be either minor (9mm, .38 Special, and down-loaded .40 S&W, for example) or major (.40S&W and larger). However, in order to score major, a Limited-10 (as well as Limited) pistol must use a .400 caliber or larger bullet.
As its name implies, the Open Division allows for the greatest range of pistol and sight modification. Pistols used in Open Division competition are the shooting equivalent to the Formula 1 race car. They are custom built with parts and features specifically designed for competition. The most notable modifications are the use ofrecoil compensators and red dot optical sighting systems. The overall length of the magazine is restricted to 171.25mm. While the most popular cartridge in the Open Division is one of several variants of the .38 Super, shooters may compete with a pistol chambered in any caliber that takes a .354" or larger bullet. While USPSA rules previously prohibited 9×19mm from scoring major power factor in the Open Division, that rule has since been relaxed and 9mm Major has become popular in consequence.
The USPSA ranks its shooters in classes, according to their performance on classifier stages. The ranks are:
