The Gemtech GM-9 piston offers shooters the ability to change threads on host firearms in a tool-less fashion. Created for use on 9mm pistols, the GM-9 piston allows you to use your preferred silencer on standard threaded pistols (1/2x28), and metric threaded handguns (m13.5x1mm). This piston more than covers your 9mm needs, so be sure to grab one for your next gun-run outing.
Silencer Shop Note:
These pistons also work with older Multimount and Tundra Silencers.
