A blank firing gun is a type of firearm designed to produce a loud noise and muzzle flash without firing a projectile. Instead of bullets, it uses blank cartridges, which contain gunpowder but no solid projectile. These guns are often used in film production, theater, and training exercises to simulate real gunfire without the risk of injury from bullets. While blank firing guns can create realistic sound effects, they can still be dangerous if misused. The gas and debris expelled from the muzzle can cause injury at close range. Therefore, safety precautions are essential when handling these firearms, similar to those used with real guns.
