The Colt Single Action Army revolver, alternately known as the Peacemaker, Model P, or Frontier, is the most popular handgun on the American Frontier and the definitive firearm of the Old West. The Single Action Army action is a refinement of the earlier Colt percussion revolvers and the Colt 1871 cartridge revolver. The cylinder is mounted on a central axis and operated by a hand with a double finger whose more extended action allowed the cylinder-ratchet to be cut in a larger circle, giving more torsional force to the cylinder. This is the seventh Peacemaker Centennial manufactured in 1973 to commemorate the 100th anniversary of the Peacemaker. It features a case-hardened finish and wooden grips. Its grips are its bore are in excellent condition and its metal is in very good condition.
