The Colt Single Action Army revolver, along with the 1870 and 1875 Smith & Wesson Model 3 "Schofield" revolver, replaced the Colt 1860 Army Percussion revolver. The Colt quickly gained favor over the S&W and remained the primary U.S. military sidearm until 1892 when it was replaced by the .38 Long Colt caliber Colt Model 1892, a double-action revolver with swing-out cylinder. By the end of 1874, serial no. 16,000 was reached; 12,500 Colt Single Action Army revolvers chambered for the .45 Colt cartridge had entered service and the remaining revolvers were sold in the civilian market.
