Mossberg 930 JM 22" Questions?

[Trinimon]

I have both the Versamax Tactical and the JM Pro. I won't repeat the information already stated here as it seems correct from my experience in particular the 3" vs 3.5" marked on the barrel of the VMT. Casey told me the same thing. If I had done my research properly I would not have chosen the VMT. Casey made a competition Versamax for a friend of mine that is better than the stock VMT.

I like the loading of the JM Pro off the bat. I don't like that the Versamax has a cartridge release which is an extra step in the loading process. JM Pro just has a bolt release. I suppose you can train yourself through that.

The carrier for the VMT is a killer. It is forked and will definitely take a bite out of your hand in fast reloading. I'm trying to find the time to get someone to do this in Vancouver toute suite. Also to be nicer the loading port should be beveled.

The Versamax is built tighter and slightly lighter. It is built better. I like the VMT's foreend better / the JM Pro's foreend is cheapish. I had a very poor experience with the JM Pro with cycling issues, shell stop problems. I should have sent it back immediately and after a seemingly endless back and forth just took it back and sent it to Tacord who sorted it out by replacing the spring and rebuilding it. It now seems to run pretty good though. I learned I should leave gunsmithing to others and send back lemons.

On the plus side they both shoot quite well now. Buckshot, target loads, slugs. I think they are pretty close in terms of recoil. I like both sights.

Wow, thanks for the comparison! Food for thought for sure.

According to Casey at Tactical Ordnance, the VMT does in fact have a 3.5" chamber, it's just not marked as such due to feeding issues with 3.5" rounds in the extended magazine.

You are absolutely right. I think legally though it only matters what is marked on the gun.

On the Mossberg 930JM;
You should also replace the follower with a S&J Hardware follower.
The sharp corners on the metal factory follower tend to get caught where the extension joins the tube.

Any other replacment follower options out there that you know of?

Yeah, there's tons.

Nordic components makes one that's very popular with 3-gunners.

Thanks. If I experience problems with the OEM one I look for those. Cheers.

I've had good results with the nordic follower in my versamax.

Contact Casey at Tactical Ordnance; he lengthens, welds and polishes VMT carriers regularly, a JM Pro carrier shouldn't be much different.

There's a place called "Southern Kentucky Tactical" that sells aftermarket lifters for the Mossberg 930.

They work great.
