I have had a 930 since they first cam out (2005?), it is the field model with walnut stock and 28" barrel. I originally bought it on a whim, but it has become my go-to 12ga. 10,000+ rounds through it with no problems. It will cycle everything from 3/4oz reloads to 3" mag steel and slugs without a hiccup. It is also one of the softest shooting autos I have fired.
I have also sold a bunch of them in various configurations, and IME it is as reliable as any other gas gun on the market, and will digest a much wider range of loads than an inertia gun without beating you up with recoil.
