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.

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).

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 ...
The Taylor KO factor multiplies bullet mass (measured in grains) by muzzle velocity (measured in feet per second) by bullet diameter (measured in inches) and then divides the product by 7,000, converting the value from grains to pounds and giving a numerical value from 0 to ~150 for normal hunting cartridges.
The .460 S&W round is a lengthened, more powerful version of the popular .454 Casull, itself a longer and more powerful version of the .45 Colt.For this reason, the .460 S&W Magnum can be considered an example of a "super magnum".
The 10mm is slightly less powerful than the .357 Magnum with high-performing commercially-available ammunition, or hand-loaded .357 magnums, and well below standard .41 Magnum rounds. The cartridge is considered to be high-velocity, giving it a less arcing flight path upon firing (also termed "flat-shooting") relative to other handgun cartridges.
