Single Action Shooting Society

Cowboy action shooting (CAS, also known as western action shooting, single action shooting, or cowboy 3-gun) is a competitive shooting sport that originated in Southern California, US, in the early 1980s. 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), as well as others in the US and in other countries.

CAS is a type of multi-gun match utilizing a combination of pistol(s), rifle, and/or shotgun in a variety of "old west themed" courses of fire for time and accuracy. Participants must dress in appropriate theme or era "costume" as well as use gear and accessories as mandated by the respective sanctioning group rules.

CAS requires competitors to use firearms typical of the mid-to-late 19th century: single-action revolvers, lever-action rifles chambered in pistol calibers, and side-by-side double-barreled shotguns (also referred to as Coach Guns – with or without external hammers, although automatic ejectors are not allowed), or pump-action shotguns with external hammers (similar to the Winchester 1897). Winchester 1887 lever-action shotguns and Colt Lightning slide-action rifles are also allowed in competition. Both original and reproduction guns are equally acceptable. All CAS handguns must be "single-action", meaning that the hammer must be manually cocked before each shot can be fired.

Competition in a CAS match generally requires four guns: two revolvers, a shotgun, and a rifle chambered in a centerfire revolver caliber of a type in use prior to 1899. Some CAS matches also offer side events for single-shot "buffalo rifles", derringers, speed shotgun, and other specialty shooting. Replica firearms are available from companies such as Ruger, Colt, Uberti, Pedersoli, Stoeger, Chiappa, Pietta, Armi San Marco and U.S. Fire Arms Mfg. Co.
