Cowboy action shooting
Cowboy action shooting (CAS, also known as Western action shooting, single action shooting, cowboy 3-gun, and Western 3-gun) is a competitive shooting sport that originated in 1981 at the Coto de Caza Shooting Range in Orange County, California. Cowboy action shooting is now practiced in many places with several sanctioning organizations including the Single Action Shooting Society (SASS), Western Action Shootists Association (WASA), and National Congress of Old West Shooters (NCOWS), and Single Action Shooting Australia (SASA).
