Here's my pic. Took it out fired 10 slugs and 4 buckshot through it. At just 10 yards it was about 5" high and 3" right for the right barrel, and 5" high and 5" left for the left barrel. It was bitterly cold so I didn't bother trying at any other distances.
The fore end was very tight before firing, and now it wiggles slightly so I may have to adjust that. The left "hammer plate" (what the whole hammer assembly is attached to) tightens a bit too far at the rear so the hammer is rotated slightly out and impacts distinctly off-center. It may be my fault when I took it apart and re-assembled it though--I obviously don't know anything about SxS guns in general (I bought one of these, didn't I?).
The left trigger wiggles back and forth quite a bit (the tip travels about 3/4 cm): the pin that holds it on is a bit loose and that trigger is right at the end so there is quite a bit of lateral play. Don't know if that is common for these, but as long as it doesn't slip completely off...
Overall, it goes boom which is all I really need it to do. I don't have any specific use for it, and it will spend most of its time hanging on the wall. Even when the zombies comes, I'll probably opt for the 870. Not overly thrilled with it, but it is about what I expected and it seems with a little tweaking it could be made decent enough. If someone wanted it for $300, I'd probably sell it, but for now I'll keep it at least as a conversation piece and a bad ass wall hanger (next to rest of my Mall Ninja gear).
