Developed by John Browning and introduced in 1905, the .45 ACP cartridge was designed for use in the Colt Model 1905 pistol and later became famously associated with the M1911, which was adopted by the U.S. military in 1911. The cartridge uses a .451-inch nominal bullet diameter and is commonly loaded with a 230 grain projectile, although lighter and heavier bullet weights are also widely available. Known for its substantial bullet diameter and relatively moderate operating pressure, .45 ACP has remained a popular handgun cartridge for more than a century and continues to be chambered in a wide variety of semi-automatic pistols.
