My 9mm suppressor just came in, FINALLY. Gemtech tundra 9mm. im going out sunday to go shoot and going to take my sbr'd mp5 and the suppressor. I have a few other handguns that are 9mm/threaded so the suppressor will be roated on those guns probably more than the mp5. I tried googling the question but couldnt find the answer.... what if i put the suppressor with the "booster" on the mp5? dont get me wrong, im going to make sure i do put the adapter in, but since I couldnt find the answer, i was just looking to see if anyone else could answer it.
