Suppresor pistons are used for attaching handgun suppressors to semi-automatic pistols. The piston acts as part of the Nielson device, which allows for movement and reliable semi-auto cycling. The piston also contains the female threads for attaching the suppressor to the host weapon. Silencerco pistons are easily interchangeable, allowing for one suppressor to fit a multitude of weapons, as well as allowing suppressors of larger bore diameter to be used on smaller calibers, (i.e. a .45 caliber suppressor being used for a 9mm pistol).
The Silencerco pistons are made from 17-4 Stainless steel and heat treated for longer operational life.
These pistons are compatible with the following suppressors:
