Gemtech GM-9 Piston
MSRP

A piston, sometimes called a Nielsen device, screws into the back of a pistol suppressor. Most pistol barrels tilt as the action cycles, and the weight of a suppressor can stop that. The piston adds a spring between the suppressor and the barrel so the pistol keeps cycling. Match the piston's thread to your pistol's barrel.
This one fits suppressors that take the Gemtech GM-9 Piston and barrels threaded 1/2x28.

Is something on this page wrong?
2 suppressors in the catalog take this part, all of them from Gemtech. That is a single-manufacturer interface, so your options are limited to that line.

Which ones fit your barrel and host?
See all 2 in the Builder- The Linear Inertial Decoupler (LID) is required for handguns using a Browning-type action (Glock, SIG, HK and similar) so the pistol cycles with the suppressor weight on the barrel.
Is one of these wrong, or does our wording say something the source doesn't?
