380 Auto Ammo

The .380 ACP (Automatic Colt Pistol) pistol cartridge is a rimless, straight-walled pistol cartridge developed by firearms designer John Browning. It was introduced in 1908 by Colt, and has been a popular self-defense cartridge ever since. Other names for .380 ACP include .380 Auto, 9mm Browning, 9mm Corto, 9mm Kurz, 9mm Short, 9×17mm and 9 mm Browning Court (which is the C.I.P. designation).

NOTE: It is not to be confused with .38 ACP, 9mm Ultra, 9mm Makarov or 9mm Parabellum.
