The Thompson Machine Poseidon9 I ordered arrived at the dealer I work for... I love it! Amazingly quiet for its size. I must say I like shooting it without the wipe. With a small amount of ultrasound gel , the suppressor gives a peasant sound/tone for about 8 shots before I noticed it getting louder... My dumb a$$ ran it 15 rounds (indoors, concrete walls standard pressure Hornady Critical Duty 135gr) and still did not experience any ringing in the ears (I wouldn't recommend that). I gotta say, I'm impressed by this little can! As soon as the paperwork clears, it's going on my nightstand gun. Seriously considering a .45 version, too.
