I remember an old MythBusters episode where Adam made a gun to shoot a nail into a concrete wall. Expecting to zipline on the cable attached to the nail. Impractical. When you hang on the cable, it pulls the nail out with a lot of force. To get the nail in in such a way that it would not come out, you need a lot of force. That force comes from the bullet in the gun. "Every action has an equal and opposite reaction." The gun would go backwards into the guy who shot it. With a lot of force. That would hurt. Even if you made the gun heavier.
