Automatic revolver

An automatic revolver also known as semi-automatic revolver, is a revolver that uses the recoil energy of firing for cocking the hammer and revolving the cylinder, rather than using manual operations to perform these actions. As semi-automatic firearms, the shooter must manually operate the trigger to discharge each shot.

Examples of genuine semi-automatic revolvers are extremely uncommon, and the term is inaccurately applied to break-open revolvers with a mechanical linkage ejector that automatically empties spent (and unspent) casings from the cylinder upon opening of the breech.
