Acp

Developed by John Browning, the .45 ACP was adopted as the official military handgun cartridge by the U.S. Ordnance Department along with the Colt-Browning automatic pistol in 1911. The .45 ACP has been the official military cartridge of several governments.

The .45 ACP was originally designed with a 200 grain bullet for the Colt Model 1905 semiautomatic pistol. It was standardized with a 230 grain bullet for the Colt Government Model 1911 pistol.

Since then it has been proven in combat worldwide. Along with the 1911A1 pistol, the .45 ACP has been developed into a first class match cartridge with accuracy fully equal to that of any other cartridge.

The .45 ACP cartridge and the Colt automatic began to be replaced in 1985 as the official military handgun cartridge by the Beretta 9mm in support of NATO standardization. However, the .45 ACP remains a favorite for competitive shooting.

The SAAMI Maximum Average Pressure for the .45 ACP is 21,000 P.S.I. The SAAMI Maximum Average Pressure for the .45 +P is 23,000 P.S.I.
