    Hi guys... new to the forum. Like many, I kinda have my eyes on eventually maybe doing some 3-gun competitions. The 930 JM Pro seems like a great way to start given its price, but the more I read about it, the more I'm inclined to stay away from it. It seems to have lots of problems.

    What I'm wondering.. what are the most typical problems, and what can be done to correct them? I'm a DIYer so I can learn to fix most anything; that which I can't I'll go to a gunsmith for. BUT... if I'm gonna end up having a ton of money tied up in it, I'd be better off saving for a Benelli.

    So I thought I'd ask... at the risk of asking one of those "this has been asked a thousand times, why didn't you search" questions. And yes, I did search. And read and read and read.

    Thanks! :)

    I've heard some of the problems that some JM pro owners have experienced. I've had my JM for about 2 months now ,and shot the hell out of it. While shooting it like crazy. I eventually started shooting low brass shells around 1200fps. Not one failure , after 400 rounds.Then I did the same thing with shells that were 1150fps. One failure after 6 rounds. Cleared the failure , and fired the rest without a problem. For reliability I only shoot shells that are 1300 or more fps. Great shotgun. I believe most of the malfunctions are due to firing super low power shells. My JM pro will cycle # 7 1/2 shot without a problem.

    That's good to know, thanks! If I hear more like that I'll feel better about getting one.

    When I was shooting my JM pro. I was trying to get it to fail on ammo. The other day I was shooting#8 shot and it ran fine.
