Many guns are included in patents, though mostly its the specific mechanism's be it a fully automatic design or a way for making sure projectiles of only a certain brand fit into the gun. Many guns are never patented, either because their designs are not unique or there's really no need to pay lawyers for something they don't need to protect.
