Actually, I should amend my original comments about the gun to include this.
The rings were installed in the wrong order out of the box with mine, and it drove me batty the first day out at the range. Once I got it in the right order, it has been fine ever since.
I'll throw my hat into the ring. It was my first semi shotgun and a great place to start. It's hands down more reliable then my 870, cheaper and a lot more fun to shoot. The feedgate sucks though. My fingers tend to get chewed up a bit.
