Description
These Pistons are considered legacy technology parts but are available for users who choose not to upgrade to either the CAM-LOK® (Covert Application Mount – Locking) Universal Piston System or the EZ-LOK™ Universal Rapid Index QD Piston Attachment System. These are available in popular but limited thread pitches.
These Pistons are for use with the Revolution™,Resistance®, Optimus® 9mm, and Bushwhacker® 46 in their 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

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.

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!

I have these installed in a CGS Mod 9SK and a Rugged Obsidian 9. Both suppressors function flawlessly with no baffle strikes or suppressor walk off. Makes securely swapping between weapon hosts quite easy.

Works great to attach my revolution 9 can to my 19x MOS and my 43x. Yeah direct thread takes a few seconds longer to attach, but I don’t need any adapters

Was looking for a piston for my AK 9 mm and I needed something that will keep it concentric and this were great. KP-9 with Cash9k with fixed spacer. Was a tight fitting pistol in my suppressor but it worked flawlessly, very happy with this part.
