Pretty hard to improve on a Beretta 390 as a dedicated waterfowl gun, IMHO. Mine has been through it all....ice, mud, water, extreme cold etc., and it has never failed. I have a set of Patternmaster choke tubes with it that have also served me well. Within our group, there are Brownings, Remingtons. Benellis, Franchis, Winchesters and Mossbergs. None have been any better, and some not as good as my old 390.
