Gemtech GM-9 Multimount L.I.D. – 1/2x28

Run your suppressor the right way. The Gemtech GM-9 Multimount L.I.D. (Linear Inertial Decoupler) in 1/2x28 is an essential piston booster designed for suppressed 9mm pistols with tilting-barrel designs. Without it, most handguns won’t cycle properly under the added weight of a suppressor, making this OEM Gemtech part a must-have for reliable performance.

Product Overview

This Gemtech L.I.D. piston threads directly onto your 1/2x28 TPI barrel and connects seamlessly to the GM-9 suppressor. It allows the pistol’s barrel to unlock and cycle correctly by momentarily decoupling the suppressor mass during recoil.

Built from hardened steel and engineered to Gemtech’s exacting tolerances, this L.I.D. is not just a booster—it’s a safeguard for function, alignment, and long-term suppressor health. Compatible with most 9mm pistols threaded 1/2x28, it ensures smooth, reliable operation with every shot.
