I bought a 930 soon after they came out, couldn't resist. It's been flawless for me, and has been my go-to gun for trap, skeet and waterfowl for years now. Cycles everything.
I like it so much that's what I got for my daughter, the synth camo version 930. It's also been flawless in action.
But my buddy has a camo 930 and he's had some trouble with it. But it could be the result of dropping it in the water and not cleaning it properly.
