M1911

The Colt 1911, designated by the U.S. military as the "M1911", is an American single-action, semiautomatic handgun that was used during almost every conflict in the 20th and 21st century. It is chambered in several calibers, originally and most commonly .45 ACP but sometimes .38 Super as well as others. In 1991, Colt started producing a modified design called the 1991, but still produces the same design that was used during WWI. It is now produced by many popular manufacturers, including Auto-Ordnance, Dan Wesson Firearms, Fusion Firearms, High Standard Manufacturing, Kimber, Les Baer, Nighthawk Custom, Norinco, Olympic Arms, Para-Ordnance, Rock River Arms, SIG SAUER, Smith & Wesson, Springfield Armory, Taurus, and Wilson Combat.

History
The M1911 was designed by John M. Browning and was produced by Colt. The M1911 was used by the US Army during World War I, World War II, the Korean War, and the Vietnam War. The M1911 was produced quickly during World War II because of the demand for weapons. In 1990, the US Army replaced the M1911 with the M9. Even after being replaced, some M1911s were used up until the mid 1990s by reserve units, and it is still commonly used today by law enforcement and civilians.

Call of Duty and Call of Duty: United Offensive
The M1911 is the sidearm used by the Americans. It has a seven-round magazine, mediocre accuracy and does average damage. It is only useful when the player does not have time to reload his primary weapon or if his primary weapon is bolt action and he needs to engage close enemies.

Call of Duty 2
Exactly the same as it is in Call of Duty.

Call of Duty 4: Modern Warfare
The M1911 in Call of Duty 4: Modern Warfare is actually either a MEU(SOC) M1911 with Strider Knives Simonich Gunner Grips, or the Kimber ICQB, which is a Kimber Warrior with Simonich Gunner Grips. In single-player, it has a seven-round magazine and appears in Hunted, Shock and Awe, The Sins of the Father, and Game Over. In multiplayer, it has an eight-round magazine and does the same damage as the USP45 and has a lower magazine capacity, but is more accurate. Like the M9 and USP45, it can be fitted with a suppressor.
