USPSA also provide minor and major scoring based on power factor. Metric targets are divided into the scoring areas A, C and D with minor and major points 5-3-3-1 and 5-4-4-2 respectively, while IPSC targets are divided into the scoring areas A, C and D with minor and major points 5-3-1 and 5-4-2 respectively.
The Federal Bureau of Investigation briefly field-tested the 10mm Auto using a M1911 pistol and a Thompson Model 1928 submachine gun [19] [20] as an "urban carbine" before adopting the Smith & Wesson Model 1076 in 1990; a short-barreled version of the Model 1026 with its slide-mounted decock/firing pin block safety supplanted by only a frame ...

Announced to the public in early 1996 at an NRA convention, the 9×23mm Winchester cartridge was claimed to have the lowest recoiling load and still qualify for Major Power Factor designation in the IPSC. [2] [4] The IPSC Power Factor (PF) is equal to bullet weight in grains times muzzle velocity divided by 1,000. A PF of at least 175 was ...
This is a table of selected pistol/submachine gun and rifle/machine gun cartridges by common name. Data values are the highest found for the cartridge, and might not occur in the same load (e.g. the highest muzzle energy might not be in the same load as the highest muzzle velocity, since the bullet weights can differ between loads).
9mm Major is a wildcat cartridge of the 9mm Luger specifically for competition pistols designed to handle very high pressure. It is used in practical shooting competitions like International Practical Shooting Confederation (IPSC) and United States Practical Shooting Association (USPSA) to achieve a "Major" power factor, which earns more points for hits in specific zones on paper targets ...
Most handgun projectiles have significantly lower energy than centerfire rifles and shotguns. What they lack in power, they make up for in being small and lightweight, lending to concealability and practicality. Handgun power and the effectiveness of different cartridges are widely debated topics.
For a 2011 pattern handgun, aftermarket parts and magazine tuning can increase the (reloadable) capacity from 14 to 18 rounds for .45 ACP, from 17 to 21 rounds for .40 S&W and from 20 to 24 rounds for 9×19mm. The power factors for Limited and Standard also differ.
