380 AUTO 100 GR RNFP REMAN 500 ROUNDS

380 AUTO 100 GR RNFP REMAN 500 ROUNDS (9×17mm) (Automatic Colt Pistol) is a rimless, straight-walled pistol cartridge developed by firearms designer John Moses Browning. The cartridge headspaces on the mouth of the case.^[5] It was introduced in 1908 by Colt, for use in its new Colt Model 1908 pocket hammerless semi-automatic, and has been a popular self-defense cartridge ever since, seeing wide use in numerous handguns (typically smaller weapons). Other names for .380 ACP include .380 Auto, 9×17mm, 9mm Browning, 9mm Corto, 9mm Kurz, 9mm Short, and 9mm Browning Court (which is the C.I.P. designation). It should not be confused with .38 ACP. The .380 ACP cartridge is also somewhat of a misnomer, as it does not strictly conform to normal cartridge naming conventions that are named after the diameter of the bullet. By standard naming conventions, the .380 AUTO 100 GR RNFP REMAN 500 ROUNDSshould be called a .355 ACP, as the bullet in the cartridge is .355 inches in diameter.
