In IPSC competitions all handguns must have a power factor of at least 125 kgr·ft/s (≈ 2.47 newton seconds), and therefore almost anything of 9×19mm or greater caliber will meet the minimum required power factor. The minimum power factor rule is designed to mitigate the speed and accuracy advantages of smaller calibers.
Although not originally designed for handguns, several rifle and shotgun cartridges have also been chambered in a number of large handguns, primarily in revolvers like the Phelps Heritage revolver, Century Arms revolver, Thompson/Centre Contender break-open pistol, Magnum Research BFR, and the Pfeifer Zeliska revolvers.
A guide to the recoil from the cartridge, and an indicator of bullet penetration potential. The .30-06 Springfield (at 2.064 lbf-s) is considered the upper limit for tolerable recoil for inexperienced rifle shooters.

The Bren Ten (left) and Smith & Wesson Model 610 Classic (right), 1983.. When FFV Norma AB (now Norma Precision AB) designed the cartridge at the behest of Dornaus & Dixon Enterprises, Inc. for their Bren Ten pistol (a newly developed handgun with a design inspired by the CZ 75), the company decided to increase the power over Jeff Cooper's original concept.
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 9×19mm, but at the cost of more ...
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.
Consequently, firearms that fire .460 S&W are usually capable of firing the less powerful .454 Casull, .45 Colt, and .45 Schofield rounds, but this must be verified with each firearm's manufacturer (most lever-action firearms can only feed cartridges within a certain overall length and bullet profile range). The reverse, however, does not apply ...
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 ...
