Does anyone have any first hand knowledge about the Mossberg 900 shotgun.? I'm wanting to get a new turkey gun, and one feature I like is a pre drilled receiver for scope or red dot attachment. The Mossberg fits that bill. I am not interested in a 3 1/2 in gun so the 835 anf 935 is out. Just wondering if people where getting reliable service out of there gun, and what kind of patterns they were getting. Thanks
