Very good field gun but it's good pointing qualities come at the cost of recoil. True of most o/u guns. Also the break action design is not something you will like if your are hunting from a blind. These two reasons are why most waterfowlers use big gas operated autoloaders.
Never had any trouble with my Brownings. I prefer an automatic. That third shot sure comes in handy on waterfowl. The advantages with the over-and-under are the ease of switching between duck loads and goose loads and not ejecting my reloaded hulls out of the blind. With automatic ejectors, without an automatic safety, and a shell strap on the stock with a couple of shells in it you can get very fast at putting two more shells in the gun for two more quick follow-up shots.
Before you invest in a o/u for waterfowl borrow one to shoot,get some 3 inch duck and goose loads and shoot a round of skeet/trap (if they allow you to use
hunting loads at you club,some don't) and you may understand why we all shoot autos.Just trying to help.
Browning makes Citori's in camo. Ceasar Guerini also made a Waterfowler with matte bluing on the barrels. Beretta also has models that will fit the bill. Be sure to buy a model that is a true waterfowl gun, not a light game gun that happens to be chambered for 3" shells as it will be uncomfortable to shoot and difficult to rebound with the 2nd shot. Unfortunately a good waterfowling O/U will not typically do double duty as an upland gun. Simply to heavy to lug around afield. I currently also use a semi-auto, but I'd prefer to be shooting an O/U.
