Outlaw Henry Mc Carty/William Bonney, aka "Billy the Kid" and General George Custer and his troops, and any number of lawmen, cowboys and just about anyone else on the frontier used the Colt SAA revolver. Colt makes them equal." Production of the Colt SAA was stopped several times, but was restarted repeatedly because of public demand.The most favored among collectors are the "first generation" (1873-1941) SAA revolvers.
The Colt Single Action Army was designed for the United States government service revolver trials of 1873 by Colt's Patent Firearms Manufacturing Company and adopted as the standard military service revolver.
The revolver was popular with ranchers, lawmen, and outlaws alike, but as of the early 21st century, models are mostly bought by collectors and re-enactors.
Its design has influenced the production of numerous other models from other companies.
The Colt Single Action Army has been offered in over 30 different calibers and various barrel lengths.
It is perhaps the most copied, fraudulently modified to replicate an original Colt SAA, than any other revolver made.
