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.
SilencerCo threaded barrels come with a Thread Protector.
Glock Barrel Compatibility: Our threaded barrels are compatible with the following Glock handgun generations:
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).
SIG 320 barrel compatibility: Our barrels have been proven to work with these 320 models only:
P320 Full Size:
P320 RX Full-Size
P320 Nitron Full-Size
P320 Compact:
P320 RX Compact
P320 FDE Compact
