Sorry folks,but I have inertia and gas shotguns...inertia guns suck ass,ammo fussy,kick hard,if you don't hold em right they don't cycle. Bought a Mossberg 930 this spring,light kick even with heavy slugs,cycles crap loads reliably,(federal 1150fps birdshot). My m3 only cycles heavy loads. Benellis and any other inertia guns are crap! Sorry but they suck and you got raped like me if you bought one! Love you all.
