Suppressed Armament has had a .45 ACP suppresser in production for almost 15 years. Never advertised or promoted in the way that it deserves, we are making every effort to correct that error. The .45 IMPACT performs dry at a level most of our competitors can only achieve when being fired "wet". The 45 ACP suppressor is available in titanium or aluminum. Replaceable booster pistons allow you to easily swap to any barrel thread currently in production.
