There is, really, only one six-shooter. It’s the one that won the West, the one that every cowboy wanted, the one that captured hearts all across America during the early days of the silver screen. Also known as the Single Action Army, the M1873, and the Colt .45, the Peacemaker was the most wildly successful metallic-cartridge-firing handgun of its day. Together with the Smith & Wesson Schofield, it superseded the 1860 Army. It served as the military’s service revolver from 1874 to 1892, and remains one of America’s favorite six-shooters to this day. The Peacemaker has been chambered in more than 30 calibers, offered in myriad different barrel, handle, finish, and metal configurations, over three different “generations.” If I had to choose only one six-shooter, it would be this one.
