Firearm suppression refers to the use of devices, commonly known as suppressors or silencers, that attach to the muzzle of a firearm to reduce the noise, muzzle flash, and recoil generated when the weapon is fired. These devices work by slowing and cooling the gases that exit the barrel, which minimizes the sound produced during discharge. While often associated with hunting and shooting sports, firearm suppression is also utilized in military and law enforcement applications to enhance stealth and reduce the risk of detection. The legality and regulation of suppressors vary by country and region, with some places requiring permits or specific licenses for ownership.
