.45 ACP

The .45 ACP (Automatic Colt Pistol) cartridge is a handgun cartridge designed by John Browning in 1904 for use in his prototype Colt semi-automatic pistol. It was adopted by the United States military in 1911 and served as the standard issue sidearm cartridge for the U.S. Armed Forces for over seven decades.

The .45 ACP cartridge is known for its stopping power and has been widely used in military, law enforcement, and civilian applications. It is a popular choice for self-defense, target shooting, and competition shooting.

Due to its effectiveness and popularity, the .45 ACP cartridge is chambered in a variety of firearms, including semi-automatic pistols, such as the Colt M1911, Smith & Wesson M&P, Glock 21, and many others. Its reputation for reliable performance and considerable stopping power has cemented its status as one of the most iconic handgun cartridges in history.
