The design spread to virtually every other manufacturer of 1911 as well, until almost all of the 1911s being sold on the market, regardless of manufacturer, could trace themselves to a Series 80 design. The Series 80 was a monstrous success on both the commercial and military/law enforcement markets and promptly replaced the Series 70. The new Colt Series 80 also incorporated the new barrel bushing of the Series 70, while being more reminiscent of the original M1911 by having a long trigger and flat mainspring housing. On this model, Colt added a safety feature in the form of a firing pin block system that made it impossible for the weapon to discharge if dropped or thrown on a hard surface. Then next major design came in 1983 with the Colt Mark IV Series 80.
