So I needed to add a 12ga back into the collection after trading out the last couple I had, after much internal debate between the Mossberg 930 & Benelli offerings, I decided to go with the 930 SPX.

After trying to source locally with no success, I came across this particular one on Vance Outdoors (I believe it shipped out of their Hebron Oh store). I wasn't familiar with Vance, but after a quick check with my brother who is a LEO in Oh, he stated that his department gets a lot of stuff from them and they are 100% legit. So, pulled the trigger & had it transferred to QRF and that was that.

I had originally intended to keep it stock, but then I thought, Meh, What the hell - I can always take stuff off I didn't like or caused it to be too heavy.

1st up was to throw on a sling I had sitting around (5.11 2-point adjustable vtac) - and it was the right color to boot .... and you just aren't a true operator if you don't color coordinate, right?

With an empty weight of 7.75 lbs, the addition of the sling was negligible

Next up was the addition of some GG&G accessories, specific to the 930 line. I chose GG&G due to the number of available reviews and for the simple fact that I've used several of their products in the past with no issues.

1. 6 shell side saddle (part # GGG-1516)
2. Sling mount with small pic rail; GG&G calls it a Sling & flashlight combo mount (part # GGG-1622)
3. Enhanced follower (part # GGG-1440)
4. Flashlight mounting ring with .900 insert (part # GGG-1249

Obviously, none of the above parts are really necessary, but none were too expensive (other than the side saddle), however, they all add weight as quality made accessories tend to do. Fully loaded with side saddle also loaded, toss in a Sparc red dot, and she now tips the scales at nearly 11 Lbs. Yep, that extra ammo adds a lot of weight..... and it doesn't help that 4 of the shells on the saddle are 3" 00 buck :p

So on to the details:

The side saddle was easy to install, and as stated in several reviews I read, you must be careful to not over-tighten and compress the receiver. They do not include the blue Locktite that the instructions recommend, but already had several tubes laying around. I found that over-tightening even the slightest bit would cause the bolt to bind. This is my biggest concern currently and I won't rely on this for HD until I have time to go to the range and put enough rounds through it to verify I have the tightness dialed in to prevent cycling issues.

The "enhanced follower" is in the tube, not much to show there, just a replacement that is supposed to help prevent cycling issues; Several reviews of the 930 claim that the juncture where the Choate extension meets the tube can cause some feeding snags, so I went ahead and dropped $22 to be on the safe side.

Stock Photo:


The sling mount with the small picatinny rail and flashlight mounting ring - I had a spare Surefire sitting around (I think its 230 lumens), while it does add to the weight, I have a couple different TLRs that I could mount on the rail to reduce weight and gain the added laser, but for now, the flashlight does the job.

930 - 1.jpg

I didn't really need the sling connection points, but it offers two connections; I decided on this over a barrel clamp that also had a pic rail for a couple of reasons.

1. There are limited offerings when it comes to barrel clamps with attached rails & the manufacturer for the most popular version does not make one specifically for the Choate extension (they make it for a Nordic extension which is a bit larger in diameter).

2. I had planned on using a standard flashlight and it didn't make much sense to me to have a flashlight mounted so far down the barrel/tube where it would be a pain to actuate unless I added a pressure switch. With the sling/pic mount, it puts the flashlight right in front of my hand where I can easily use my thumb to depress the 2-brightness stage end-cap button; the only downside with this light is that if I want the light to stay on, I would have to twist the end cap to keep it on hands-free, but for my use, I prefer to use my thumb to actuate the momentary button and choose the brightness based upon pressure. The next option, should I seek a light that stays on with one press, would be my Fenix, but don't really see the need at the moment.

While I'm fine with the current sling connection at the front, at least I have two other options should I decide to go a different route.


Lastly, I tossed on a Sparc red dot just for kicks & giggles - it doesn't co-witness as well as I would like, but it's not likely to stick around. I will run it just to see how well the Sparc holds up to the recoil, but the stock sights are more than enough, especially with a light onboard.

The SPX comes with a "stock spacer system" that may be used to adjust the vertical position of the stock up or down, from 1/4" down to 3/8" up; I've decided I'll shoot it a good bit first and then decide if I need to change it.


So there it is, the first part of my working review of the 930 SPX; I'll update this once I get a chance to take it to the range and break it in. I'm not set on what accessories will stick around, but I do like to have options, and well, I just like playing leggos with my guns ;)

More to follow!

Great review. The main question I have is about the side saddle shell holder. I was wondering why you chose that option rather than a stock shell holder? I understand that based on the type of stock you have mounted may be a challenge. Just curious.

Honestly, I didn't even research stock-type shell holders due to experiences I had in the past with the elastic type losing retention capabilities; after about a year of use & recoil, they seemed to droop/hang a bit. Maybe I had a bad one :noidea:

I had a receiver-mounted saddle similar to this one on a Mossy 500 that I liked, so I just instinctively went that route - but again, these are accessories that I'm not married to, it could go either way after some trial/use.

I think they have models with velcro or straps now instead of elastic. The side saddle looks like it is made out of plastic. Just curious how it would stand up to heat cycling and recoil shock?

Certainly a potential option; Not too worried about heat as this will likely reside bed-side for HD once fully tested - I do wonder about fitment though .... the 930 SPX has an odd stock curvature.

In any event, it's not like I really need to carry around another 6 shells on top of the 7 + 1 (+ another 1 if I ghost load) for HD ....... but it may not be a bad thing if the Zombie apocalypse strikes and I'm out in the fray :)

The 930 SPX has an odder curve than my... oh, wait that is another forum. There may be a model for yours out there somewhere. Anyway, the HD option is the one I would be concerned about with the side saddle if it can potentially cause cycling issues. I think you should have xtra ammo handy apocalypse or not, it is more how you carry it. Definately glad you did not go with the bandolier on a sling option!

Naw, not going the mall-ninja-bandolier route :nono:

From the reviews I've read on cycling issues, it seems to come down to not over-tightening and letting the Locktite do it's job; but there is no specific ft/lbs torque value listed in the instructions (I have also emailed GG&G to see if they have any specific insight on this).

So at this point, it will be trial & error to see precisely how tight/loose the bolts need to be. Another option, if I really want to stick to this particular side saddle and avoid any cycling issues, would be to forego the mounting bolts and just use some adhesive Velcro / hook & loop, but I'm hopeful that I won't get to that point.

I installed a rail mount system on my father's 870 and the unit replaced the trigger pins. The screws were shoulder type where the threads were just enough to engage the threaded holes on the mount so that bottoming out the shoulders provided proper tension. Not sure of the screws supplied with your kit are threaded longer or engage the mount differently, but I would think if not you could find some that did. If they do go through the trigger assembly then you can probably go pretty snug with them and not affect the action. If there is not any kind of buffer between the saddle and the side of the SG then I would find some thin rubber sheet and cut a piece and install between saddle and SG. This will keep the saddle from moving around as much. If you are get to the point where you are considering Velcro, I would either keep it as semi-permanent and attach with a plastic type epoxy or abandon all together.

Finally had a chance to get to the range today, ran about 20 rounds of 2 3/4 00 buck, 40 rounds of the cheap Winchester universal 2 3/4 low brass and a few 3" 00 buck. About midway through the box of low brass, I had 1 FTE, It ran the high brass and 3" shells without issue.

Recoil was not as bad as I thought it would be with 3" 00 buck, but not as soft as a Saiga 12ga. Did a quick inspection of the accessories after I got home and none had loosened up, the Sparc held zero without issue as well.

Will update again when I have a chance to run some more low brass through it and see if the reports of a "break-in cycle" hold true.

ETA: Just finished a full strip and clean, I might be inclined to believe the stories of the break-in period now that I have seen the numerous points of wear on the bolt and slide.

Is 625$ a good price for the Blackwater 930SPX?
New, yes, that's a good price, used, no.

The only downside (for me) is the Blackwater has open ghost ring sight on the rear and unprotected blade sight on the front where the other SPXs have the LPA rear ghost and winged fiber-optic front sight. The only other difference is the Blackwater logo on the side. (Not to be confused with the Walmart 930 with standard stock, breacher barrel and bead sight)

Another range trip & another 60 rounds of cheap Winchester universal 2 3/4 low brass through it with nary an issue at all. So that brings the total now to:
100 total rounds of low brass
20 rounds of 00 buck
Probably 8 rounds of 3" 00 buck.

1 or 2 more trips and a few more boxes of low brass and I might be satisfied that it is "broken in"

No, that is $625 new on GunJoker. I could have gotten the standard 930 SPX for the same price>

If that's the buy now price on Gunbroker, then yeah, I'd say its a good deal

Cool. I am keeping my eye out. I am torn between that and a this little baby right here:
