Revolving pistols, or revolvers, were a leap forward in the development of guns as they allowed the shooter to fire several shots before the pistol needed to be reloaded. Although Colt is not recognised as the sole inventor of these guns, he is credited with their widespread adoption.
Colt's Colt 1851 Navy revolvers, 'six shooters', were made by machine in factories, and therefore had interchangeable parts, allowing for the guns to be repaired quickly and easily. They were also cheaper to produce, as they required fewer skilled workers within the factories. They have come to be associated with the Wild West in America.
