Mossberg 930 JM Pro Review

jackson923 · Oct 15, 2012

@TWSS
I like the stippling job you did. Is that a carbon fiber Lancer forend? If it is what did it cost you and how long till you got it?

JM PRO UPDATE: H&H has the 22" in stock for $609

If it would've been the 24" I'd be posting pictures right now

DonC · Oct 17, 2012

So what advantage does the 24" have over the 22"?

The only difference is that is it a 10+1 instead of 9+1

The 22" gun is an 8+1 and the 24" is a 9+1. I have the 8+1.

Thank you sir. The ar came from the factory with that handguard. I think Loki makes it themselves.

24" barrel also gives you more velocity which helps a lot on stubborn steel targets or those that are farther away.

Why did you remove the barrel/tube clamp? Just courious because I thought about it but then wondered if the weight of the rounds would cause it to can't and not feed correctly.

I took it off because I didn't want to have it negatively affect my POA/POI when shooting slugs. If you don't put back in the exact same spot with the exact amount of torque it will likely change point of impact. Maybe not much, but I didn't want to take any chances.

As for the feeding. I've not had any issues. I know plenty of people run the +8 tubes with no ill effect, barrel clamp or otherwise.

I thought that is why you always shoot 3" high brass at all the matches?

I am glad to hear that this is a reliable gun. I have been eye fondling this shotgun for awhile.

I've been looking for a 24" JM pro for a while now with no luck. Does anyone have a lead on what the quickest option is to get one. thanks! -Todd

Not sure about the 24", but I may know where you can get a good used 22" version. Stay tuned.

MiniUzi · Jan 13, 2013

sure 22" is fine as well... what's a couple of inches

twss · Jan 13, 2013

That's what I keep tellin' myself. Be happy with the 22" you got, don't get greedy and go for a full 2 footer.

Well I sold this one. Maybe the new owner will keep updating the thread. He's a member here.

Man, that Mossberg and I sure had some fun times.

jackson923 · Feb 8, 2013

If your on the fence about getting one I will throw this out there. I have 100's of rounds through mine with only 1 failure to eject completely. Was shooting with a guy yesterday and his FNH was having issues, he told me today it was something with his lifter that he was able to fix, it ran fine today for him.

MiniUzi · Feb 8, 2013

I still can't find one anywhere... I don't suppose anyone has the hookup with Mossberg ? I've called them and they can't even give a straight answer as to what is shipping and when. It's a bit discouraging.

Uberelite · Feb 13, 2013

This is what I got when I emailed Jerry via facebook. I am looking for one as well.

Mossberg introduced the JM model in January of 2012. Unfortunately, they
grossly underestimated the popularity of the JM930 shotgun. They have
now increased production, but are still trying to catch up with demand.
Hopefully there will be more showing up at stores soon.

Gunbroker.Com had 13 today for $730.00, so I pulled the trigger and bought one. That is the buy it now option. One at auction just went for $1225!! INSANE!
