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.
The 100th Anniversary 1911 from Colt is a special edition pistol produced in limited numbers. It features custom rollmarks on the frame and slide that detail the 1911s storied history. These pistols have unique serial number formats and come in commemorative 100th Anniversary packaging.
