45 ACP Ammo

The .45 ACP (Automatic Colt Pistol) cartridge was developed by legendary American firearm designer John Moses Browning 1904. Its most notable application is the iconic Colt M1911 pistol which served as the standard-issue handgun of the U.S. military between 1911 and 1985.

.45 ACP ammo may have been eclipsed in popularity by the 9x19 Luger cartridge, but it still has a dedicated following among sporting shooters, hunters and fans of the Great Outdoors.

Despite having considerably more recoil than 9mm ammo, the heavy .45 ACP rounds are appreciated for its high stopping power, which is essential for hunting or self-defense.
