ok, i haven't done anything, yet...so no worries... i live in texas, so i think i'm okay. but if someone could quickly answer this or send me a reference, i would appreciate it. its a bit of a dumb question... but my question is, is it legal to put a pistol grip & a forward vertical grip on a shotgun? i wasn't aware of any rule prohibiting in my state, but i wanted to be sure that there wasn't some state or fed law i was unaware of. thanks.
