I have a Moss 500 with foward and rear grips, its my back-up to a Glock. I think the only downfall in close-range self-defense is the inability to use the buttstock as a weapon. It took some practice but i can be very accurate with quick firing at tactical ranges. The foward grip helps me with the recoil as much as anything. Wrist pain for a week after a day of shooting made me try the front grip. My load consists of 00, Slug, 00, Slug,........ If that doesnt work, I'M RUNNING!
