The M1911 is a semi-automatic, single action, recoil operated, magazine fed handgun chambered for a .45 ACP cartridge.


The Colt M1911 has a seven round detachable box magazine and a total weight of about 2 pounds. It has a muzzle velocity of about 250 meters per second. It also has a total length of about 200 mm and a barrel length of about 127mm.[1] The design of the M1911 was very rugged, with all the moving components well secured within the slide. Attached to the side of the metal frame were grips that were either made of rubber or wood.


The only variant of the M1911 series was the M1911A1, produced some time after the end of World War I in 1924. The Colt M1911A1 had some minor differences to the original Colt weapon such as a shorter trigger. Some other differences include a wider front sight to assist with aiming, and a simplified grip.[2]


The Colt M1911 was adopted by the United States Army in 1911 while the Marine Corps and Navy adopted it two years later in 1913. The M1911's first major usage was in World War I as a standard sidearm for the United States infantryman. Encountering great success, the M1911 continued to see service with the US Army into World War II as the M1911A1 variant. Its ruggedness allowed it to see service in a variety of environments which would otherwise destroy other pistols such as the famous German 'Luger'. The M1911 continued to be used well after World War II.

It soon became a favorite of military personnel and even though attempts have been made to replace it with the Beretta M9, many users complain it lacks stopping power and requested an M1911, proving the quality of this weapon. It has recently celebrated its 100th anniversary, and is also arguably one of the most popular handguns of all times.
