I have a Benelli M1 super 90 I use for home defense. Ive been trying to find good light mounts but have no luck. Sense benelli has discontinued the M1 most the stuff i find has been out of production for awhile. The only thing I've found are the small rail segments that attach to the front of the tube but having tried those on other guns im worried about it falling off under recoil. Is there something I havent found yet? Is it worth maybe upgrading to an M2?
