The Ruger Old Army revolver is unusual in that, unlike most percussion revolvers on the market, it was not based on a historical design, but was a modification of Ruger's Blackhawk model, which was itself based upon the cartridge-firing Colt Peacemaker. Models were made with a 7.5' and a 5.5 inch barrel. The Ruger Old Army is a black-powder percussion revolver introduced in 1972 by the Sturm, Ruger company and manufactured through 2008.
