Although revolvers existed before the early 19th century, the mechanism patented by Samuel Colt in 1836 led to widespread use of the revolver. The typical revolver uses a revolving cylinder with multiple chambers from a single barrel. Guns like the Colt Single Action Army, the Smith & Wesson Model 10 and the Colt Police Special made revolvers into a legendary staple of war, law enforcement and everyday shooting. Although the introduction of semi automatic pistols in the 20th century may have replaced the revolver as a wartime weapon, they continue to be popular choices for law enforcement, competition shooting and concealed carry. From double action to single action models, Wholesale Hunter has excellent selections from top manufacturers like Colt, Smith & Wesson, Ruger, Taurus, Magnum Research and more.
