Yes, it should work with the 106 pistol. You have the 106 pistol with the 10.5 inch barrel, correct? I assume since you want to cut the barrel down. You shouldn't need to mess with the gas system once the barrel is cut. But the flash hider on your pistol is fake and I remember that once you remove the fake hider there are no threads underneath. So, you would need to either replace the fsb, thread the fsb (don't know what kind of threads you can put on it as the original threads of 24mm can't be threaded as it is turned down to 22mm I believe; maybe turn it down to ar style), or you can cut down the barrel only a little bit and thread the barrel for ar muzzle devices just befor the fsb.
here is a picture of what the fsb looks like under the fake booster in this thread.
