The Colt SAA revolver is a famous piece of Americana, known as "The Gun That Won the West"

The Colt Single Action Army which is also known as the Single Action Army, SAA, Model P, Peacemaker, M1873, and Colt .45 is a single-action revolver with a revolving cylinder holding six metallic cartridges. It was designed for the U.S. government service revolver trials of 1872 by Colt's Patent Firearms Manufacturing Company – today's Colt's Manufacturing Company – and was adopted as the standard military service revolver until 1892.

The Colt SAA has been offered in over 30 different calibers and various barrel lengths. Its overall appearance has remained consistent since 1873. Colt has discontinued its production twice, but brought it back due to popular demand.
