I own S&W, Ruger and Charter Arms handguns. Remington and Mossberg shotguns, and Marlin and Savage long rifles. Never had a problem with any. Now ammo that is another question altogether. I have fired friends Glocks and Sigs at the range and they worked well and were quite accurate. I used an M14 in basic. Shot fine and was quite accurate. Would like to have one today.
