I picked up a Browning Maxus Stalker (the straight black synthetic one) about 3 months ago. My primary use for it is waterfowl hunting. I had some experience with the gun as one of my buddies goose hunts with a 10 gauge, so he allowed me to use his Maxus while we were goose hunting pretty extensively for a year. Cycling 3 inch goose loads it performed flawlessly so I ordered mine in (I got a 26 inch barrel and the only one on the shelf locally was a 28 inch). Well mine ended up coming in about a week before I left for a Missouri snow goose hunt, and I wasn't completely expecting the gun to show up before the hunt. I ended up getting out and shooting some trap before the trip to make sure everything was going to function. I ended up running about 4 boxes through it that day without a single issue whatsoever. On the 2 day hunt I ended up shooting I think 3 boxes of shells, no issues whatsoever. Functionally it's a great gun and I can't say I've ever heard of anyone having any issues with them.
As for the fit, I must say I was pretty impressed. The gun swings nice, it shoulders beautifully, and it points well. The one issue I could possibly see someone having is the forearm. It is a wider grip compared to a lot of current guns that go with more slender lines (see the Winny SX3 or even an SBEII). For me it feels comfortable and shoots comfortably. If you've handled one and like the fit, then I'd say pull the trigger.
I have also been fairly impressed by the patterning of the factory chokes. I believe Briley makes the factory Invector + chokes but don't quote me on that. I know a lot of guys shooting trap and skeet that use the Diana grade extended chokes but being a waterfowler I have gone the route of the Patternmaster and Carlson's Black Cloud chokes.
Enough with my rant though, let us know if you get the gun and how you like it!
