My second post! I hope to shoot my new 935 Waterfowl next week at the Camp Atterbury range. I know I've seen a patterning frame there but I didn't see it last Saturday when I shot some trap and skeet with one of my 500's. I'm going to get a JM 930 Pro mag tube and piston assembly as well as some OR3GUN parts. I'll be "having my cake and eating it too" if I can get it to cycle with moderate 2 3/4" target loads as well as 3" and occasional 3 1/2" loads.
