These Pistons are considered legacy technology parts but are available for users who choose not to upgrade to the Universal QD Piston System.  These are available in popular but limited thread pitches. 

Future planned thread pitch support:

  • 1/2x28
  • 13.5x1LH
  • .578x28

These Pistons are required for use with the Revolution™,Resistance®, Optimus® 9mm, and Bushwhacker® 46 in the pistol configurations. 

It is important to intermittently clean and lubricate the exterior of the piston and interior of the booster housing to ensure smooth reciprocation with the O ring in the piston retainer.
O-Rings should be replaced intermittently when worn to ensure alignment of the silencer with the booster assembly. Failure to replace damaged or worn O-rings could result in a baffle strike or damage to the piston components.

Piston are H900 heat treated with a rust inhibitor. Please note, color and color pattern will vary due to the heat treatment.


Features :

  • H900 heat treated for improved durability and wear resistance 
  • 17-4 stainless steel material

    Like everything Griffin makes, this was high quality. Running it in a Rev 45 mounted to a Glock 22.

    Griffin's Products Work as Advertised

    Published by Erwin on 9th Dec 2019

    I wanted to be able to use my Revolution 9 on my Sig P239 Tac. I was taken aback to find out Sig uses a LH 13.5X1 thread on the barrel since nothing is mentioned about the thread size in the owners manual. I was pleasantly surprised that Griffin makes the correct piston for the Revolution 9 and they had it in stock. I installed mine as soon as it arrived and it fit perfectly, both in the Revo9 and to the P239. Function was flawless with both subsonic and supersonic ammunition. Great products!

    great products

    Published by mike hobson on 1st Oct 2018

    The parts that I ordered are well built. The quality looks great. Will buy again. I only gave a 4 star because they didnt have a part and do not make it.
