"S×S" shotguns are often more expensive, and may take more practice to aim effectively than a "O/U". The off-center nature of the recoil in a "S×S" gun may make shooting the body-side barrel slightly more painful by comparison to an "O/U", single-shot, or pump/lever action shotgun. Gas-operated, and to a lesser extent recoil-operated, designs will recoil less than either. More "S×S" than "O/U" guns have traditional "cast-off" stocks, where the end of the buttstock veers slightly to the right, allowing a right-handed user to point the gun more easily.
