Blank-firing guns are firearms designed to produce a loud noise and muzzle flash without firing a projectile. They use blank cartridges, which contain gunpowder but no bullet, making them popular for training, film production, and theatrical performances. These guns can closely mimic the look and feel of real firearms, providing a realistic experience without the risk of injury from projectiles. While blank-firing guns are often used in controlled environments, they can still pose safety risks. The gases and materials expelled from the muzzle can cause injury if fired at close range. Proper safety measures and training are essential when using these devices, especially in settings involving actors, stunt performers, or military training.
