Colt Single Action Army

The Single Action Army — also known as the Model P, Peacemaker, M1873, Single Action Army and SAA — is a single action revolver with a revolving cylinder holding six metallic cartridges.

The Single Action Army has been offered in over 30 different calibers and various barrel lengths. The revolver was popular with ranchers, lawmen, and outlaws alike, but current models are mostly bought by collectors and reenactors. Its design has influenced the production of numerous other models from other companies.
