Colt Series 803
Colt series 80, or mk. iv series 80, are a line of firearms introduced in 1983 by Colt's Manufacturing Company. The main difference between this guns and the previous Colt series 70 is that the former incorporate a new firing pin block safety system, consisting of a series of internal levers and a plunger positively blocking the firing pin from moving until the trigger is pressed, hence eliminating the possibility of the gun going of if dropped onto a hard surface or struck hard. Other than that, the Colt series 70 and the 80 series do not differ too much from one another. On the other hand, there is really no difference between the Colt 1911 series 80 and the M1991A1, which is mechanically the same as the colt 1911.

The Colt 1911 is a single-action, semi-automatic, magazine-fed, and recoil-operated handgun chambered for the .45 ACP cartridge. The Colt series 80 was designed by John M. Browning and is still carried by some U.S. forces. It had widespread use during World War I, World War II, the Korean War, and the Vietnam War. Currently, several law enforcing agencies and military organizations still use the colt 1911, such as the Marine Corps Special Operations Command, Los Angeles Police Department S.W.A.T. and L.A.P.D. S.I.S., the FBI Hostage Rescue Team, F.B.I. regional S.W.A.T. teams, and 1st Special Forces Operational Detachment—Delta and The Tacoma, Washington Police Department, in the United States alone. Other countries which have also used it at one point or another include Argentina, Bangladesh, Bolivia, China, Colombia, Ecuador, Fiji, Greece, Guatemala, Haiti, Indonesia, Liberia, Mexico, Nicaragua, Spain, and others.
One of the reasons that the Colt 1911 is so popular is because it is easy to customize, allowing modifications such as changing the external finish, checkering the frame, and hand fitting custom hammers, triggers, and sears, as well as installing compensators and adding accessories like tactical lights and scopes. This property has made the series 80 a highly sought after item, not only by the military and police forces, but also by the general public. Most people use it either for target shooting or for protection. The name Colt has also been ingrained in popular culture since the days of the Wild West. For instance, legendary characters Wild Bill Hickok, John Henry "Doc" Holliday, Richard Francis Burton, Ned Kelly, and Robert E. Lee used to carry a Colt Navy, a predecessor of the 1911. Other vintage pistols are the Colt Army Model 1860, the Colt Dragoon Revolve and the Colt Single Action Army.
