Single action uses original or replica firearms that were commonly used in the Old West period of 1800 to 1899. This includes single-action revolvers, lever-action and slide-action rifles and carbines, lever-action and pump-action shotguns, and side-by-side shotguns without automatic ejectors. A unique aspect of single action is the authentic period or Western-style dress, with shoes and hats to match. This adds to the uniqueness of the sport and helps create a festive and informal atmosphere. Single action shooters are required to select a shooting alias for themselves, which is representative of a character or profession from the Old West or the Western film genre.
