This genuine Gemtech thread-mount piston in M18x1 RH pattern adapts Gemtech GM-9, MM9, and Tundra suppressors for host firearms with matching metric threads, including the CZ Scorpion EVO 3 S1 platform. A correctly matched piston is essential for reliable cycling on tilting-barrel and blowback hosts, and Gemtech's factory parts are machined to the tolerances your suppressor was designed around. If you are moving your 9mm can between hosts, keeping a dedicated piston for each thread pitch makes swaps quick and foolproof.
