Guns are a class of weapons, based in ranged attacks. They needs Ammo, found in loot piles. You can reload them by pressing "R" in your keyboard and having ammo in your inventory and when reloaded, will be capable of shooting. The unic "ranged weapon" in Minecraft Vanilla is the Bow (uses arrows) but CD:Cure adds 6 new guns and 7 new ammo types.
