I picked up my Mossberg 930SPX from an individual back in August of '09. It had 12 rounds fired through it when I got it. I know this to be fact.
I probably paid a little more than new retail for it,however it came with the following extras.
1. A wide quick detach sling with 15 shell loops. I do not like this sling as a sling per se,but keep it on the shotgun with the loops full of 00 buck. I have the sling adjusted to snap around my waist with the shells in front for easy withdrawal.

2. Two 55 round bandoliers
3. 750 rounds of assorted 00B,#4B,and rifled slugs.
4. Barrel-tube clamp with the swivel to attach the sling.
5. Additional rounds of #5 shot and #4&6 Duplex loads.

Here are some of the things I like about this shotgun.
For an autoloader it is very lightweight,fast handling and easy to swing and get on target fast. I have not measured the LOP on this gun,but for me it is perfect. The 930 comes packaged with spacers that can be used to lengthen the LOP for those inclined, who need a little longer stock.

The SPX comes with the Italian made adjustable rear sight,with protective wings on each side. I understand that this sight alone is about a $200 unit if ordered separately. I have not confirmed this. The high M16 type front sight has a fiber optic red insert which is wonderful and very fast in daytime,especially with slug loads,and using the rear sight which is a peep,zeroing with slugs is very precise. I would have preferred some kind of tritium vial on the front,however I will not change it. The rear LPA sight is mounted on a picatinny rail,secured to the receiver with four hex screws.
I've had no problem with loosening,and the sight can be easily removed with it's mounting knob/bolt for replacement with a red dot if desired,or the red dot can be mounted and the rear sight used as a co witness if desired.
I currently have no plans to do either.

The shotgun has a 7 round mag capacity plus one chambered. A popular thing about this shotgun seems to be it's ability to be ghost loaded with an additonal round free floating on the elevator,increasing the total capacity to 9 rounds. I have done this and can say emphatically that the shotgun functions in this way with no problem at all. I personally find it to be just a little more aggravation than it's worth to me to gain one additional round,however,if I knew a fight was coming and this gun was what I had I wouild probably prep it in this manner.

I find the recoil of this shotgun to be actually bordering on pleasant when compared to other shotguns with 00 buckshot. I can feel the slugs a little more,but it is not punishing at all and I'm a little bitty feller. Three inch 15 pellet 00B is a little nastier but I only shot these up because they were included in the ammo that came with the gun. The reduction in recoil can be attributed to the dual port gas piston and also the recoil spring mechanism in the buttstock.

Here are some faults or dislikes that I have discovered with this gun.

This shotgun comes with a very short metal cupped follower. This short follower has the potential to bind up on any grit or debris that gets inside the mag tube. This will cause the rounds not to feed from the tube,and this is not what you want in a defensive gun.:eek:
If this follower is not replaced it is imperitive that the mag tube be kept swabbed out and free of debris. When you are running and gunning and reloading on the move with dirty hands,grit and small debris WILL get inside the tube.
S&J hardware out of Canada makes an excellant mag follower of hi visibilty orange polymer with an extension on the front for magazine spring to slip over. Using this follower magazine capacity will be reduced by one round with 2 3/4" rounds to 6 rounds and down to 5 if you use the 3" shells,which I personally see no need for in a defense gun. The three inchers are for ducks and geese IMO. I don't see a one round reduction as a big deal when it increases reliability. I will be replacing mine with the S&J follower.
This binding HAS NOT occured in firing the gun but has occured when hand cycling rounds through the action,which tells me that the potential is there for it to happen at the worst possible moment.

The other dislike that I have is the 2 round Choate mag extension that come standard with the gun. This extension was built with an open end and a black plastic disk,for lack of a better term that fits inside the extension to cover the opening. I have intentionally pushed this disk out of alignment and thereby creating the same binding that occurs with the follower,preventing additional rounds from feeding. This is totally unacceptable to me. I am replacing this extension with an aftermarket one of better design with a solid end.
I have used Choate extensions in the past and have never been disappointed,but this design just plain sucks canal water,and I can't for the life of me figure out why it was designed in this way,except to cut costs,which is also unacceptable for fighting guns. I have a Coate extension on the 28" Rem 1100 that brings the capacity to 10+1 and have never had an issue with it in over 20 years. I will continue reviewing my personal experience with this gun in the following post.

Nice write up Doc,

Thanks for your thoughts on the 930 sir !!

I determined at the outset to test this gun in the way that one would normally run a Glock. Hard and fast shooting,no cleaning and no lubrication just to see how long it would go. I do not have an actual round count,that's just too much trouble for me to keep up with.
I have been shooting this shotgun at every range session whether the session was prmarily pistol or rifle or shotgun. I started the day after I aquired the gun in August '09 and have continued to run it with no cleaning or lube. I have disassembled and inspected it,and did swab out the magazine tube but that was extent of the care it has received. I plan to give it a thorough clean and lube on the July 4th weekend.:)

I have experienced no failures to feed or eject or any other problem in actually shooting the gun. It has been recommended that a new SPX be broken in at first with heavy loads and the gradually working down to the low recoil loads,birdshot,etc. Just to be my stubborn self I did just the opposite.
I started with low recoil buck,worked my way up to full power,then magnums,then slugs,and then shot up the three inch rounds which I have no use for. Never a problem.
The operating handle could be a little larger for better maneuvering and there are a few good aftermarket replacements available. I don't like the design of the Choate,but there are others available or coming available and I will probably get one or the other of these. Simply pull out the original and push in the new one. So simple,even I can do it.
I strongly recommend replacing the standard follower and the Choate extension. The reasons have been previously addressed. Other than these three things I believe that the Mossberg 930SPX has the potential to be one of the best,if not THE best fighting autoloading shotguns available today.
It would be nice if Mossberg listened to end users and made the necessary changes at the production level,however I don't expect to see this happen. I can recommend the 930SPX,and with just a few minor and not too expensive tweaks,can be made into a formidable and ultra reliable weapon.

I have settled on Federal Low Recoil 00B with the flite control wad as my load of choice in buckshot. Extremely tight patterning. These are the LE132's
Accept no substitutes.
The other load I will use in this gun is the Brenneke Tactical Low recoil Home Defense slug. Penetration in big animals,folks,and car bodies is unquestionable with these slugs.
I think anyone who chooses this shotgun will be extremely happy with it.
We now return the control of your computer to you. Keep your eyes on the skies.

Sounds like a great gun with the two mods you mention, Doc. Thanks for the excellent review. I want one!!

Michael,if you buy an SPX be sure to check the front sight before you put your money down. There were some complaints early on about the front sight being canted. I believe this problem has been fixed now but check it well just the same.I got lucky,as mine did not have the cant.

The trigger housing assembly may have some slight side to side movement but this is characteristic of the breed and not a problem
Incidentally,the trigger on these guns has a very short and smooth break.Use that safety.

Doc, will do, thanks. It will be a while though, I am dirt poor at the moment.:( I fondled one a few weeks ago at the gun shop, and I REALLY liked the way it felt, and the ergonomics of it.

Excellent review!

I have been wanting to get a semi-auto shotgun so I'll check it out. I hunt with Mossburg 500 and being a lefty I like the position of the safety over the Remington, Benelli or Beretta.

I like the fact that it will cycle with reduced recoil buck shot and slugs.

7677.thanks. I have been using 870's since I was 11 and have been accustomed to the crossbolt safety. This is my 2nd Mossberg,the other being a Maverick and I do like the tang safety for speed.
With a few minor modifications,I think the SPX is an excellent gun for it's intended purpose.

Doc,
I have come to the decision on what combat shotgun I'm going to get. I compared the Mossburg to the Benelli M1 with rifled sights and the Benelli M1 won out. I will post a review next month after I get back from Europe.

Doc,
...and the Benelli M1 won out.

That's because the Benelli is drop-dead sexy. I love that gun.

The Benelli is a most excellant choice,and I don't think anyone who knows anything would argue that point. I'll look forward to your review. The Mossberg was the more economical choice with the deal I got,but having owned a Benelli myself I can see the lust for one. Great gun!

I picked up my Benelli M1 last weekend and I can't wait to shoot it. I decided on a used one with rifled sights that appears to be like new condition and had not been shot much. Plus, the price was too good to pass up.

Last night, I went through my 12GA ammo selection and picked out several different loads to test this weekend.
