The Colt 80 is part of a series of classic semi-automatic firearms under the name ‘Colt 1911.’ The origins of the Colt 1911 semi-automatic dates back to 1911, when creator John M. Browning designed it. Its use became wide-spread as the standard side arm for the armed forces of The United States during World Wars I and II. The Colt 1911 was also used in the Korean and Vietnam wars. Many adaptations have been made over the years, but one of the most well known occurred in 1983, when he designed The Colt 80, or M1911 80 Series. The 80 Series of Colt guns, became the first to include an internal firing pin for safety purposes. The internal firing pin on this series of semi-automatic firearms, prevents the gun from firing, unless the gun is in battery, and closed fully.

The Colt 80’s use of firepin was invented to prevent accidental shots from firing, particularly when the firearm is dropped. Gun Smiths of The Colt 80 began charging more for manufacturing due to the fact that the trigger took longer to sharpen than the average semi-automatic. Many complained of the rough lurch they felt while pulling back the firing pin, saying that the operation in all, was not smooth. On the flip-side, studies show that the ‘rough’ lurch one may feel while trying to operate The Colt 80, is due to execution as opposed to a flaw within the design.

Not many complaints are made about The Colt 80 and its supposed design flaw anymore, mainly due to the fact that Colt itself is rarely purchased these days. Many choose their semi-automatic guns to have a grip firing pin safety as opposed to the traditional Colt 80 trigger operated firing pin. Two notable manufacturers producing the grip operated pin, include Kimber, and Smith & Wesson.
