The .38 ACP (Automatic Colt Pistol) also known as the .38 Auto was introduced at the turn of the 20th century for the John Browning-designed Colt M1900. It was first used in Colt's Model 1897 prototype, which he did not produce. The metric designation for the round is 9×23mmSR (SR—Semi Rimmed) (not to be confused with the modern 9×23mm Winchester or the .380 ACP).
