Hey all, I'm looking to upgrade my Mossberg 930SPX spring and follower to ensure it doesn't bind when fully loaded.

Have any of you done any upgrading in the spring/follower department?

I don't have a 930 so i'm not sure of the exact details of how the follower is built, but on my 500 the follower was just a little steel cap in a similar shape to the older 870s. I decided to try a Scattergun Technologies high vis follower designed for 870,1100,11-87. It's shaped completely different and has a little post coming off the back of it that rides in the middle of the spring. It works fantastic in my gun but on some of the reviews for the part people were complaing about losing capacity with it. Before, under stress of trying to haul ass, I could accidentally get an 8th shell in my 7 round magazine tube, and it would bind the cartridge stop, and interrupter and be frustrating to dig back out. Now it'll load about 1/4 of a cartridge past the 7th shell plus one in the tube, giving me a good confirmation it's full without having a cartridge almost stuck when I lose count of how many I have fired. Ive never had a spring binding issue so I dont know if this would help but I can say it worked well for my application. OH... Btw How do ya like that 930? I've been eyeing them (My brother in law has a SPX) but I've never had alot of trust for autoloaders besides a friends old Browning auto 5. Does it load everything well? I'm looking for something to swap barrels back and forth to shoot clays and to have for hd going back and forth from low brass field loads all the way up to slugs and 00 buck like I do with my 500.

I have a 930 SPX and found that when I loaded the magazine up with Federal's LE132-00 buck that I lost capacity by one shell. Searching in the internet, I found a post on AK47.net (give credit where it's due), that suggested using the spring from a regular M500.I tried it and sure enough, I gained the 7th shell capacity.
The difference in length between the LE-132 isn't much, about >.< this much. But when you add it up >......<, that was enough to prevent the last shell from going in. I don't know what effect a follower with a tail would have, but you may lose capacity unless you are willing to trim the tail.

On a related note, did you know that you can 'ghost load' a shell on the carrier of the 930 to give a 7+1+1 all up capacity? :)

well honestly if its not broke dont fix it.

unless you are having problems i dont see the point of it and personally i would trust the factory one that is made for that gun over an after market one made for a different gun.

About 3 out of 10 times I fully load it the spring binds and I have to get out an allen wrench and remove the light mount and unscrew the mag tube extention to fix it which is a huge problem during a competition or home defense situation.

I went with the Choate follower in my Mav 88, plus a new factory spring after 14 years and thousands of rounds. The Choate follower has a tail like the Scattergun Tech one does. Yo uwill probably lose a round of capacity (since you said it just barely fits now) but you at least won't be binding up your gun at a critical time.

Sounds like you're cramming in an extra shell though. Most shotguns have a little extra room built in - if your shotgun's capacity is listed for 3" shells, you could definitely be cramming in an extra if you're using 2-3/4" shells.

The 930SPX is listed as 7+1, I put 7 in, racked it and then added one more so I shouldn't have been putting in more than the stated capacity.

I went ahead and ordered the S&J follower.



I heard it works great to prevent binding and I like the hi vis look and nipple to be able to quickly determine there are no more rounds left.

I'll lose one round capacity (Nordic stopped making the extention for the 930 that fixed this) so I ordered this Mesa side saddle:



I know they make 6 and higher side saddles but for the purposes of competitions I'm in this is plenty to make it through a round.

I've heard mixed reviews about the Mesa but I figured I test it for myself.

I think you made the right call with the 4-round sidesaddle. I looked at the 4 and 6 but ended up with the 4. It seemed to throw the gun less off balance than the 6 rounder.

Lots of folks add the 6 if they're adding a holder the the right side of the stock as well, which balances it out a bit (but 12 extra rounds is a lot of extra weight!)
