Good grief can we just call the silencers and have a noun that does not need any adjectives? That's what the law calls them and what's on Maxim's patent.
Yep. You could take a silencer and fill it full of concrete. It would still be a silencer. It doesnt matter what the device does.
I have no idea why people feel the need to call them suppressors. The term "suppressor" was conceived as a PC naming suggestion from a hack soldier of fortune writer in the 70's in an attempt to make them more palatable to government procurement officers who wouldnt be caught deal signing off on a silencer purchase.
