I have finally (other than a few safe queens) consolidated all my firearms into 3 calibers, I have threaded barrels on nearly all of them now: Ive seen a few threads talking about best the suppressor for the money. Cost is not an factor for me. I also don't care if it is small or large. I will prep any firearms still needing it (ie: recoil boosters, etc). Barrell lengths on firearms intended for use with these vary from 3.5-8" With all that out of the way: What are the best (quietest) suppressors that exist in .22 , 9mm, and .45. Do they still make 2-stage suppressors?
