Just one issue I wanted to mention about the SXP. I originally thought this might have been just a fluke with my first barrel. Until it happened again to a second brand new barrel.
This shotgun doesn't like to hold on to it's bead sights. The barrel that originally came with this gun had the bead sight fall off and get lost the second time I took it to the range (within about 500ish rounds) I then installed an aftermarket sight from Brownll's. Eventually I cut the barrel down and haven't gotten around to redrilling and reinstalling the sight.
The second barrel I bought recently. Took it to the range for the first time yesterday and within 100 rounds, the sight is gone, nowhere to be found.
The problem is this is no longer the American Winchester that uses standard U.S. thread sizes for it's beads. They use metric sizes so good luck finding a sight at your local gunsmith or online retailer that will just screw in. You'll have to drill and tap it to the next larger US size and install a new bead like I did.
Or now that you are aware of this issue, if you still have your original sight. Might be a good idea to fix it in there with some red loctite or a dab of epoxy.
Otherwise the gun's been excellent.
