CAN they make it tamper proof? I do know if you change the grip its not legal(without the stamp). Then I cant carry it around in my backpack..I wondered about maybe sanding an angle into it, but I have to buy one first and look at it. Almost bought one a week ago but got sidetracked.I can't believe they got that 14" barrel by the ATF just by putting that long grip on it. Theoretically speaking, COULD one remove it to install a proper pistol grip on it like a regular 500 or a 590 or did they make it tamper proof?I do love my Mossy Shocker.
