Is it Silencer or Suppressor?
We have a variety of sound suppressors available for purchase here at Spillway Sportsman.
Silencer is by far the most commonly used term for that accessory that goes onto a barrel of a gun and makes it quieter. Historically, people have used the term silencer most often, and a quick Google search shows nearly 20 million results for the term silencer.
Also, the US Dept. of Justice refers to them as silencers as does the ATF. The legal definition (18 USC § 921) states:
The terms “firearm silencer” and “firearm muffler” mean any device for silencing, muffling, or diminishing the report of a portable firearm, including any combination of parts, designed or redesigned, and intended for use in assembling or fabricating a firearm silencer or firearm muffler, and any part intended only for use in such assembly or fabrication.
Suppressor is a term used most often by manufacturers, people in the gun industry, and it is becoming more and more popular with shooters and hunters. And it makes sense; after all, the device in question does not silence the gun, it suppresses (reduces) the amount of noise generated when a shot is fired. It does not stop the sonic boom – the crack you hear when a supersonic bullet leaves the muzzle faster than the speed of sound, although a suppressor used in combination with a Subsonic ammunition does result in a quiet shot.
