Designed by John Browning, the Model 1911 was the standard-issue side arm for the United States armed forces from 1911 to 1985 and is still carried by some U.S. forces today. The Model 1911's longevity is due to Browning's often-imitated design, which incorporates the short recoil principle. The M1911 is a single-action, semi-automatic, magazine-fed, and recoil-operated handgun chambered for the .45 ACP cartridge. While many manufacturers have produced this firearm, Colt is the original and the most trusted. This is an original 1917-manufactured military pistol that has not been reworked or refinished. The pistol has been reworked by the Augusta Arsenal with an aftermarket trigger, grip safety, stippled frame, and barrel bushing. The handgun's other features include Bo-Mar adjustable sights, a 2-position safety, wooden grips, and a 6-round magazine. Its wood, metal, and bore are all in good condition.
