Im a fan of browning o/u,made my citori sporting special into a poor mans trap gun. After 20+ years and 1000's of trap rds it never missed a beat,not sure what browning has done to enhance the citori lineup these days but i was eye balling the 725 sport model.
Keep in mind browing is a ejector breech loader,heavy trigger pull is browning m/o (5lb top5.5lb under)safety protocol ,further youll find browning ou's top barrel shoots flat 50/50 at 30yds and 60/40 lower couple hours spending time to fit ( if you know what to do) and do a visual on your intended shot load on pattern board.
If you purchase new you'll have stock shims,spacers ( if you have long arms) to set correct "lop" (length of trigger pull) purchasing a shotgun new off the store gun rack and expecting it to fit like a glove is a faliscy example little guy 5'4 vs a big guy 6'+ wont fit well w/o some tweaking unless your intended use is a couple weekends in the field then whocares youll make it work.
