Don't do it. I may catch a lot of flak for this but the Browning A5's made in the last 10-12 years have been horrible. Multiple cases of them being sent back to the factory for not cycling, Browning shipping people extractors, etc. If I'm paying damn near $2000 for a gun, it better damn well work out of the box. The old true Belgium made ones are cut from a different cloth. The issue with them is new steel beats the daylights out of the older barrels. The world is moving to bismuth which is more forgiving but it's not an off-the-shelf ammo and if you run out, you may be shooting steel. The Wicked Wings is a pretty gun. Not something I want kicking around in marsh mud.
There are two options: Beretta, Benelli. Assuming you're using this for waterfowl, look no where else. I run an A300 Xtrema which is chambered up to 3.5". It's basically an A400 without some of the bells and whistles like the "Kick-Off" extra mid bead sight, etc. That gun just runs. Low brass upland, 3.5" BB for goose, tungsten, bismuth, etc. She just eats and kills. I have probably 2000 shells through her at this point and she failed to cycle once and it was my fault. The A400 is in the same class as the A5. It's a top-tier gun. You talk to the guys down in Arkansas, they all run either Beretta A-series or a Benelli of some sort. The only downfall to the A-series is the Optima HP choke platform. It's a sport, thin-walled choke system. You'll have issues running high speed, big steel but that stuff is pure crap anyway.
Benelli is your option if you want an inertia gun. They're great. Some guys complain they are a little light. There is, of course, the "Benelli Click." This happens when the hunter accidentally pulls the bolt slightly back out of battery or doesn't run it forward enough, initially. This actually can happen with the Beretta or any gun, for that matter. A simple cursory forward tap of the charging handle is all it takes to fix the issue. Otherwise, they are held in the same regard as the Beretta A-series. In fact, the SBE1 will go down as one of the best waterfowl semi's of all time, next to the original Belgium made Browning A5's.
Waterfowl hunting accounts for about 90% of my hunting every year. I'm in the salt marsh probably 20 times a season, at least. That's not counting about another dozen field hunts for honkers and snow geese. It's some of the worst hunting conditions in the world and the Beretta A300 Xtrema never failed me.
Remember, for waterfowl...the 3 B's
Beretta
Benelli
and Boss ammo.
And please, I apologize if I offended anyone for my dislike of the new A5's. Waterfowlers in my area have very strong opinions on shotguns.
