Description

Warning : This model is suitable for Glock 21 threaded in 16x1RH (right-hand thread) manufactured before 2017. If in doubt, have your thread checked because since January 1, 2017, the thread of Glock 21 is 16x1LH (left-hand thread).

The model presented includes an inertia amplifier, which avoids having to modify the barrel or change the recoil spring.

The maintenance-free valves are made of billet aeronautical alloy. Their very sophisticated profile gives them exceptional efficiency. They will give the lowest sound level with subsonic ammunition, but conventional (or supersonic) ammunition can be used continuously without damaging it.
