A blank gun is a firearm that fires blank cartridges, which generate a muzzle flash and explosive sound that is typically 2 decibels (dB) louder than a normal firearm but does not shoot a projectile like a real firearm. Blank guns can be used for deterring and immobilising threats, such as in self defense, and can shoot both 9mm P.A.K. blank and pepper ammunition
Blank guns are non-lethal alternatives to firearms and are classified as flare guns under the Firearms Control Act (FCA), which means they do not require a license to purchase or carry.
