The CAA Roni works great for stabilizing a Glock pistol. The traditional Roni and Roni STAB share the same chassis and only differ towards the rear. The Roni has a stock and the STAB has a pistol stabilizer.
The front of the Roni has a metal shroud that helps contain the muzzle blast from the Glock from seeping out into the polymer chassis.
You can run a threaded barrel in your Glock but the problem is the metal shroud is too long.
One guy, on youtube, acquired a 10″ extended threaded barrel so that the barrel would protrude past the metal shroud.
After looking at the Roni chassis for a little bit, I noticed that I could remove the metal shroud and there is a large opening in the front that could accommodate a suppressor.
Silencer Shop sent me an AAC Illusion 9 offset suppressor to test. Even with the offset, the suppressor clears the opening of the chassis. A traditional suppressor would work just fine. There is no added benefit to using an offset suppressor in the Roni.
Here is the same Roni STAB modified to fit my Glock 35 with Lone Wolf conversion threaded 9mm barrel.
The setup works perfectly. My only issue is when shooting the short Roni STAB and cheeking the stablizer. I noticed a significant amount of gas blowback. Normally when you shoot a suppressed Glock, your arms are outstretched and that pushes the Glock further away from your face. That is not the case when shooting the Roni. So if you want to shoot the Roni suppressed, test out the can and see if you get gas to the face.
