The Colt 1873 Single Action Army Revolver, also known as the Colt .45, the Frontiersman, the Peacemaker, but most often as simply the Single Action Army (or SAA) was a single-action revolver manufactured and produced by Samuel Colt Firearms beginning in 1873. It is the firearm most commonly identified with the American Wild West and the 19th Century in general, for its widespread popularity with both civilian and military users, its appearance in numerous sensationalist news stories about shootouts, and its association with the most famous duelists and marksmen of that era, including "Wild Bill" Hickock, William H. "Billy the Kid" Bonney, the Earp brothers, and even with later figures such as General George S. Patton. Another of its nicknames is "The Gun That Won The West."
