Doesnt the 725 have mechanical reset rather than inertia reset that all the previous Brownings have? Thats a big design change - I suppose that offers some advantages, but why fix something if it aint broken? I own a variety of shotguns - Superposed, Citori's, Beretta 686 and Prevail III. I like the old Superposed for a field gun (3 inch action for ducks, yessir!). Of the modern guns for sporting purposes, I prefer the Beretta's for fit and feel. The kick-off system is a bonus if you are recoil sensitive.
I'm sure your 725 will serve you well - its a quality gun. Learn how to maintain it - all over and unders are prone to shooting wear. I've shot one and enjoyed it. However, the rakish styling did nothing for me. (When I spend more than 2K for a shotgun, aesthetics do come into play)
BTW - You are going to buy another shotgun.. As a minimum, you need one for the field and one for sporting purposes.
