 Despite the change, old stocks of the longer .45 Colt rounds in the supply line caused the Army to drop most of the Schofields and continue with the Colt.Major Schofield had patented his locking system and earned a payment on each gun that Smith & Wesson sold, and at the time his older brother, John M. Schofield, was the head of the Army Ordnance Board and the political situation may have been the main issue for the early end of army sales.Many of the S&W Model 3 Schofield revolvers saw service in the Indian Wars, and there are reports of them in use as late as the Spanish–American War and Philippine–American War.
