a while back i ordered a magazine extension tube for my 870 and never put it on. a couple of weeks ago i put it on and it extends about an inch beyond my 20'' barrel. is this a problem? it looks kinda weird sticking out there forward of the barrel. i thought of trading it for a shorter one but the idea of having those extra rounds ready to go is comforting. the down side it really adds weight to the gun.
