Hi, I used to have a 12ga Classis SxS, which I gifted to my son. He uses it for duck hunting and also late season pheasants. It's a very well made and stout gun, 4 locking lugs, so it won't shoot loose. His has 28" bbls BTW. When I had the gun here's what I thought of it. The fit and finish were good, the gun is a bit heavy, it is thick in the wrist. It is no English game gun as far as handling is concerned, but not too bad overall. No problems or issues with the SST, the ejectors are strong, but timing is not the best, in fact his has issues with the right ejector always tripping when the gun is opened even if that bbl was not fired ( I found out this is a common problem). Be aware that there are no after market choke tubes available for this model, so try not and lose the ones you get with it. The tubes are rated for steel except for the IM and Full tubes. Bbl regulation is spot on and the choke tubes do reflect the correct choke constrictions.
Overall, not a bad gun. You could do worse. It's an excellent waterfowl gun, but for the uplands I found it to be a bit bulky. My son likes it and that's what counts for me.
Good luck!
