The revolving action takes its name from a revolving cylinder containing a number of cartridge chambers. One chamber at a time lines up with the barrel as the firearm is fired. Revolving cylinders may rotate either clockwise or counterclockwise, depending on the manufacturer. This type of action usually is found on handguns but may be found on some older rifles. Revolving actions are referred to as either “single action” or “double action.”
