Description Acri Ammunition .380 ACP – Reliable Defensive Performance The Acri Ammunition .380 ACP (Automatic Colt Pistol) is a proven handgun cartridge with more than a century of real-world use in personal defense applications. Originally developed by legendary firearms designer John Moses Browning and introduced in 1908 for the Colt Model 1908 Vest Pocket pistol, the .380 ACP quickly earned its reputation as a dependable, compact defensive round. The .380 ACP is a rimless, straight-walled centerfire cartridge that headspaces on the mouth of the case, a design that promotes consistent chambering and reliable function in semi-automatic pistols. Its relatively low recoil and compact cartridge dimensions make it especially well suited for smaller, lightweight handguns, which is why it remains a popular choice for concealed carry and backup firearms today. Known worldwide under multiple designations—including .380 Auto, 9mm Browning, 9mm Corto, 9mm Kurz, 9mm Short, and 9×17mm (C.I.P. designation: 9 mm Browning Court)—this cartridge has seen widespread adoption across Europe and the United States.
