Help me out guys. Running 124/115 in my P320, with Griffin suppressor. With the suppressor on, many FTF and stove pipes. Without suppressor, everything is perfect. Ideas?

Need more details... which 1 ??

Maybe try 147 Grain Loads....Subsonic by Design

Piston installed or without one? Not knowing which specific suppressor model, if the suppressor was used on a rifle, it will need a piston for use on a pistol.

I have a P320 TacOps that I suppress with a Griffin Optimus. Works great.

You DO have the booster installed, don't you? And the booster spring is installed around the piston? I'm guessing you're using the booster because I don't believe Griffin makes a 13.5x1LH threaded fixed barrel adapter.



I only ask because you didn't say how much experience you have with suppressors.

I'd be interested to know what model suppressor you have, and do you have another gun you could try the suppressor on?

Yes, booster installed. This is one of many suppressors. Griffith Rev9. My rifle suppressors are dedicated to the rifle so there are no mix ups.

Try 158gr Fiocchi or a lighter recoil spring. My 19 with both Osprey and Rugged Obsidian hs the same issue, 13# recoil spring fixed it.

Just had a thought. Is the piston in the gun from Griffin? Some manufacturer's pistons will not work in other manufacturer's suppressors.

It is. A lot of use and anti-seize and it works now.
