Colt m1911 .45 pistols are designed to stop the MORO tribesmen of the philippines during the Pilippine - American War in the early 1900's
--------------------------------------------------------------------------------------------------------
The M1911 is a single-action, semi-automatic pistol (handgun) chambered for the .45 ACP cartridge. It was designed by John M. Browning, and 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. It was widely used in World War I, World War II, the Korean War and the Vietnam War. Its formal designation as of 1940 was Automatic Pistol, Caliber .45, M1911 for the original Model of 1911 or Automatic Pistol, Caliber .45, M1911A1 for the M1911A1, adopted in 1924. The designation changed to Pistol, Caliber .45, Automatic, M1911A1 in the Vietnam era. In total, the United States procured around 2.7 million M1911 and M1911A1 pistols during its service life.

The M1911 is the most well-known of John Browning's designs to use the short recoil principle in its basic design. Besides the pistol being widely copied itself, this operating system rose to become the pre-eminent type of the 20th century and of nearly all modern centerfire pistols.

Comparison of government-issue M1911 and M1911A1 pistols
M15 General Officers adopted by the U.S. Army in the 1970s for issue to Generals.Following its success in trials, the Colt pistol was formally adopted by the Army on March 29, 1911, thus gaining its designation, M1911 (Model of 1911). It was adopted by the Navy and Marine Corps in 1913. Originally manufactured only by Colt, demand for the firearm in World War I saw the expansion of manufacture to the government-owned Springfield Armory.

Battlefield experience in the First World War led to some more small external changes, completed in 1924. The new version received a modified type classification, M1911A1. Changes to the original design were minor and consisted of a shorter trigger, cutouts in the frame behind the trigger, a curved mainspring housing, a longer grip safety spur (to prevent hammer bite), a wider front sight, a shorter spur on the hammer, and simplified grip checkering. Those unfamiliar with the design are often unable to tell the difference between the two versions at a glance. No significant internal changes were made, and parts remained interchangeable between the two.

World War II
World War II and the years leading up to it created a great demand. During the war, about 1.9 million units were procured by the U.S. Government for all forces, production being undertaken by several manufacturers, including Remington Rand (900,000 produced), Colt (400,000), Ithaca Gun Company (400,000), Union Switch & Signal (50,000), Singer (500), the Springfield Armory and Rock Island Arsenal. So many were produced that, after 1945, the government did not order any new pistols, and simply used existing parts inventories to "arsenal refinish" guns when necessary. This pistol was favored by US military personnel.[2]

Before World War II, a small number of Colts were produced under license at the Norwegian weapon factory Kongsberg Vaapenfabrikk (these Colts were known as "Kongsberg Colt"). During the German occupation of Norway the production continued. These pistols are highly regarded by modern collectors. German forces used captured M1911A1 pistols, using the designation "Pistole 660(a)".[3] The M1911 pattern also formed the basis for the Argentine Ballester-Molina and certain Spanish Star and Llama pistols made after 1922.
