The Mossberg 930 is quite a good gun, reliable, accurate and very easy to service when needed. I have 2 of them and one has had literally thousands of shells, mostly 3" turkey loads, fired through it, without any failures whatsoever. I/ve used it in competition, at the range for evaluations and for hunting. It has a really great trigger and the factory recoil pad is quite good as well. At one point, I did not clean the gas system for about a year. When I took it apart, it was filthy but it just kept going.
I've only had the second 930 since last September, so not so many shells through it yet but I expect to see the same reliability from it as the first one. It's a "Snow Goose" model so it came with a magazine extension and a larger bolt handle which I really like. It also has a very good trigger.
There are many very good guns out there, lots to choose from but you would not go wrong with the 930.
Thanks,
Clark
