I find the Benelli M1 hard to beat if you have a good one. They tend to be a bit sensitive to the loads used and can malfunction if you add too much weight to the gun (i.e. sidesaddles, tac lights etc.). Personally, I prefer straight stocks to pistol grips and have heard that the M3 tends to malfunction more than the M1. I love my M1 with ghost rings and a Patternmaster choke - 6" groups at 25 yards.
