Most 9mm pistons are 1/2x 28 thread.
Some run 13.5 x 1 mm LH Sig etc.
Some fixed barrels are 1/2 x 36.

OK, I’m not sure what pistol is your host but the piston/booster will be
Either 1/2 x 28 or 13.5 x 1 LH.
It looks like Rebel has a 1/2 x 28 piston in their inventory.

Here’s the piston for 45 acp , not sure if your piston will work in DFNDR45, notice the lock nub. If piston is returnable , ill purchase one to see if it’ll work ,Thanks 15917387234031827449507|281x500

Not sure if it will work, it looks very different.
I guess the DFNDR piston is proprietary.
Can you buy a 9mm piston from Alliance?
That will probably be the way to go.
