All pistol suppressors require a threaded pistol barrel. SilencerCo noticed a market need for high quality pistol barrels and we stepped in to offer them. Holding to the same commitment to quality as all of our products, the threaded barrels are tough enough to hold up under the harshest conditions. Made of 416R stainless steel and finished in black nitride (some models remain stainless). For use with a pistol silencer, you will also need a piston (sold separately)*

SilencerCo threaded barrels come with a thread protector.

*The Glock 43 barrel comes with a 1/2 X 28 piston designed specifically for use with the 43 barrel. This unique piston will also work with all other 9mm pistols threaded 1/2 X 28.
