I also have a 930 with a 28" barrel. It's a great gun. Mine has a good trigger, crisp and with no creep. It's one gun that I've not even considered replacing the recoil pad with a Limbsaver, which is normally the first thing I do to any gun. The bore is slick and smooth and it shoots to point of aim.
I've shot the gun a lot with various shells from 2.75" trap loads to 3" turkey loads and had no failures of any kind.
It's drilled and tapped so it's easy to mount optics if you choose to do that.
If you're looking for a reliable self-loader it's certainly one to consider.
Thanks,
Clark
