ALL firearm silencers are legal in 35 states in the US. you just have to file a class3 paper on them. 200 dollar transfer tax. I have a USP tactical in 45 with a AAC can, a Deliese carbine and a Gemtech QD can for my AR-15.... they are VERY much legal.
anyway. hitman that is SWEET.. I love silencers on 1911s... pure sechs
