Harbor Springs Outdoors Club

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.
