A suppressor, also known as a silencer, is a device attached to the barrel of a firearm that reduces the noise and flash produced when the weapon is fired. Suppressors work by trapping and dissipating the expanding gases that are released when a round is fired, which significantly reduces the sound and muzzle flash. Suppressors are commonly used by hunters, law enforcement, and military personnel to reduce noise pollution and improve situational awareness. They can also be used to make firearms more compact and maneuverable, which can be advantageous in close-quarters combat or when operating in confined spaces.
Suppressors have been used for centuries, with the earliest known examples dating back to the 15th century. However, it was not until the 20th century that suppressors began to be widely adopted by the military. During World War II, suppressors were used by both the Allies and the Axis powers to reduce the noise of gunfire and improve surprise attacks. In the years since World War II, suppressors have become increasingly popular for civilian use, particularly among hunters and target shooters.
