All pistol suppressors require a threaded pistol barrel. SilencerCo noticed a market need for high-quality pistol barrels and stepped in to offer them. These barrels hold the same commitment to quality as all of our products, making them tough enough to withstand harsh conditions. They are made from 416R stainless steel and finished with black nitride (some models remain stainless). For use with a pistol silencer, you will also need a piston (sold separately here)*. SilencerCo threaded barrels come with a Thread Protector.
