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 here)*

SilencerCo threaded barrels come with a thread protector.

Glock Barrel Compatibility: Our threaded barrels are compatible with the following Glock handgun generations:

G19: Gen 1-5, 19X, G45
G17: Gen 1-4 (not Gen 5)
G26: Gen 1-5
G34: Gen 1-4 (not Gen 5)
G43: G43 & G43X

Glock 43 piston compatibility: Due to the shorter threads on the Glock 43 barrel, it requires the use of the 1/2×28 SN piston (AC1756).

P320 RX Full-Size
