I've got one.
Like Preacherman says, it is basically a 18" 6+1 winchester SX2, It is nice and short, very light, and handles well.
I really like it. I was initially disappointed because I was apparently reading FN's european website where they described the shotty as having the Browning Gold speed loading feature. Maybe it does in europe, mine doesn't.
Once I got it out on the range I quickly fell in love with it. It seems to have about half the recoil of my 870. I have about 1000 through it and have found it to be extremely reliable with the right ammo and easy to shoot accurately at speed. It doesn't like the anemic winchester 100rd pack ammo but it loves the Federal 100 rd pack stuff. It has never choked on buck or slug. I did have one FTF with the federal stuff where the mag spring was not strong enough to push the shell all the way out to drop the bolt. It has not happened since but I plan to replace the mag spring with a wolff spring when I get a chance just for cheap peace of mind.
LPA ghost rings were dead on out of the box although the front bead was not tritium as one of their many websites promised. I really like the LPA sights and plan to put them on my 870 whenever I get a chance. Last month I shot some hand-thrown clays with my SLP and found the sights to be extremely fast.
Remington 1100 stocks can be easily modified to fit the SX2 so I plan to put a speedfeed IV-s on ASAP now that the AWB is gone. The only other thing I plan to change is the charging handle. It is a little bit small so I am going to replace it with an extended one.
I do have a little bit of a lingering bad taste in my mouth because the gun lacks the speed load feature of the Browning Gold. I plan to use it for 3-gun (whenever the surplus time, ammo, and money all converge) where I feel the speed load feature would be an asset. Only one spot to reload at, no need to worry about whether you are shooting the gun dry, etc. One of these days I will find somebody who knows enough about these shotguns to tell me if it is possible to "Golderize" an SX2 with the right Browning parts.
