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-45 Piston and barrels threaded .578x28 SN.
