A lot of guns will do a great job. It all comes down to how the gun fits you. When you try a gun out a store bring it up to your shoulder with your eyes closed. Then open them to see where your sight line is. I've had both Benelli and now a Beretta. The Beretta fit me better and i shoot it much better. Also where a heavy coat or the coat you will be hunting with. Good luck. Once you go duck hunting you will be hooked.
