For those that have owned a Mossberg 930 for a long time, have you experienced any parts failures?

I am looking at getting some spare parts to have on hand should a gun related panic start and things get hard to find.

I have a sympathetic gunsmith that will order whatever I want, I just want to have an intelligent list of parts to ask for.

Sell the 930 and get a stoeger M3K
Problem solved, owned both and I was a lot more satisfied with the stoeger.

I've had mine about a year.

The Wal-Mart blow out $250 special. So far, its been finding the brass it likes. I am thinking of getting the Or3gun part upgrades.
And thinking of opening up the loading port a little.

But, then I remember I have a super reliable 870 and just put it back in the safe to play with later.
In for a tag of parts.

Everything will fail on that gun: Cracked receiver, barrel pitting, ALL of the springs will wear out. This will all happen right as the fema police are kicking your door down to take your guns. Not only will this gun rust, it will cause other guns in your safe to rust!!!

Any actual relevant posts?

I've had my JM Pro for a couple years now, haven't had to replace anything yet. I did install the OR3Gun  spacer but that's it.

I have one, 18.5 breacher barrel. About 1k rounds through it no issues. Eats whatever I feed it, patterns well enough. Only jams I had were during the first few mags worth and some bad ammo. Fwiw, It currently pulls truck gun duty.
 

Nice, thank you.

I've had many rounds through mine. Only thing that broke was a pin on the pusher assembly. Called Mossberg customer service. Very nice, and sent replacement at no charge. The reason I had to order from Mossberg was because NO ONE else stocked parts.

ETA: they take 2 weeks to ship any parts you order from them.

Thank you. So now I have one vote (or report) of a pusher assembly.

Anyone else?

ETA, approximately how many rounds until it broke?

I've had two. One for six years, both with thousands of rounds through 5 them. No recurring issues. Issues have been very rare.

Probably a couple thousand. I probably could have repaired the pusher that broke, but it was just easier to get the part from Mossberg. (One of the pins broke off from the body).

I have had mine for about 4 years. Have used it for 3 gun and some trap shooting.  Use a 24 inch barrel with a Nordic tube extension for 3 gun and a 28 inch barrel for trap.  Probably have 2000+ shells through it.  Can't see any wear that causes me concern.

Replaced the plastic spring plunger with a stainless one, welded up the lifter so it wouldn't bite my thumb, and replaced the bolt operating handle with an oversized one.  And I did open up the bottom of the receiver so I can load shells easier.

Only a couple of times has it hiccuped, and then only with heavy loads (1 3/8 oz at 1475 fps).  Generally just hand cycle the action and back in business.  Was trying to use those loads on spinners.  

Shoots slugs into a 4 inch group at 50 yards but I have to use a lot of Kentucky windage and hold over to hit targets past 25 yards.  

Overall I have been very happy with this gun.

I think the biggest thing with 930s is they need a good scrubbing when brand new, then about 50 full power loads for break in. Another scrubbin after that and gtg. When I hear about a 930 having issues I ask if they did that, answer is always a no, fwiw.
