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.
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.

According to Guns & Ammo magazine, Performance is on a par with the 10 mm, yet pressures are much milder. Factory ammo is loaded to +P .45 levels, but the lighter bullet weights make recoil comparable to .45 hardball loads. Felt recoil is a little sharper but still very controllable. [5]
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.

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.
For comparison, Hornady's 9249 load for the .500 S&W Magnum cartridge offers slightly less energy at the muzzle, achieving 2,868 ft⋅lbf (3,888 J) by driving a 300 grain (19 g) FTX bullet at 2,075 ft/s (632 m/s). Buffalo Bore's loading for the .500 S&W cartridge offers much less energy at the muzzle, achieving only 2,579 ft⋅lbf (3,497 J) by ...
Existing .45 ACP magazines are utilized with no modifications. Handguns converted to .40 Super include the S&W 4506, Glock 21, Glock 30, SIG P220, FNH FNP-45, FNH FNX-45, HK USP, Tanfoglio Witness and the 1911 Government Model (and its variants). Handguns set up for the .45 Super cartridge only need a barrel swap.
