The .45 ACP is an effective combat pistol cartridge. It combines accuracy as well as stopping power for use against human targets, has relatively low muzzle blast and flash, and it produces moderate recoil in handguns (made worse in compact models or with hot loads). The .45 ACP is generally considered to have greater stopping power than the 9mm.
Headspace of a .45 ACP cartridge, which headspaces off the case mouth. Cutaway of the barrel of a tank cannon, showing rifling on a large scale. The barrel is one of the most important factors for accuracy, as a poorly made barrel may be beyond correction. Even a quality barrel must be well matched to the cartridge it will be firing.
In the classic division a choice can be made between up to a 10-shot capacity 1911 with minor scoring (e.g. 9×19mm) or up to an eight-shot capacity 1911 with major scoring (e.g. .40 S&W or .45 ACP). In the revolver division major scoring can be achieved with a 9 mm bullet diameter, but with a power factor of 170.
It is essentially a .45 ACP case, necked down to .357, resulting in a cartridge similar in form to the earlier 7.65×21mm Parabellum and 7.63×25mm Mauser cartridges. It was created to be a low recoil target cartridge that would function reliably with multiple bullet types, FMJ to cast lead wadcutters without the feeding problems that straight walled pistol rounds sometimes exhibit.

.45 ACP: The standard US pistol round for about 75 years. Typical .45 ACP loads are subsonic. [54].45 Colt: a more powerful 45-calibre revolver round using a longer cartridge. The .45 Colt was designed for the Colt Single Action Army and adopted by the US Army in 1873. Other 45-calibre single-action and double-action revolvers also use this round.
The .460 Rowland / 11.43×24mm is a rimless, straight walled handgun cartridge designed in 1997 [1] by Johnny Rowland and developed in conjunction with Clark Custom Guns as a derivative of the .45 ACP [2] with the goal of producing a cartridge which can achieve true .44 Magnum [3] ballistic performance and be fired from a semi-automatic platform.
The .40 S&W cartridge has been popular with law enforcement agencies in the United States, Canada, Australia, and Brazil. While possessing nearly identical accuracy, [14] drift and drop as the 9mm Parabellum, it has an energy advantage [15] over the 9mm Parabellum [16] and .45 ACP, [17] and a more manageable recoil than the 10mm Auto cartridge.

B shows a concave sided SWC, typical of a lightweight .45 ACP bullet used in bullseye shooting. The concave sides reduce the bullet weight, and thus the recoil, while keeping the overall length of the bullet long enough to feed reliably in a semi-automatic pistol such as the M1911 commonly found in bullseye competitions.
