History of the 38 Auto Cartridge:
The 38 Auto also called 38 ACP or 38 Automatic was designed by John Browning and introduced by Colt in 1900, for the 1900 Colt 38 Auto pistol. ACP = Automatic Colt Pistol
The 38 ACP was replaced in 1929 by the 38 “Super Auto” which is the “same cartridge case” but with a higher energy level, with newer and different gun powders.
Warning to new shooters: Do NOT use 38 SUPER AUTO or Winchester 9x23mm in a 38 AUTO pistol, as they are to high power for the 38 AUTO pistol. Also you can NOT use 38 AUTO ammunition in a 38 Super pistol as it will not cycle the action.
