Put ~100 shells of assorted types through the gun over the past week. The only thing it choked on were the 980 FPS low recoil low noise target rounds. Other than that, all of the shells listed below fed well and were pretty accurate. I'm about 5'10 and kept the spacer in the stock. Overall, it fit me really well out of the box and was extremely soft shooting. The cast needs a little fine tuning to fit me perfectly, however, it was close enough that once I had the gun mounted I was able to stay in the gun throughout series of rapid shots with ease. The trigger is solid. It was smooth for a shotgun, did not stack and had a crisp break.
As far as how the sights work out, it seemed to shoot flat. The gun wanted the mid bead lined up with the front bead and those beads lined up with the point of impact. I did not really do any accuracy testing per se, however, I am 100% confident that the gun is far more accurate than I am. The kick off stock helps...does it help as much as adding 3 or 4 lbs of mass to the gun? Physics says no, but IMO, a lighter gun is a lot more comfortable to hold for long periods of time.
