Anyone have this in stock or had the chance to shoot one?
Kinda tough to find, some assistance would be appreciated.
Reviews, common faults, comparable options from other brands are helpful points/topics.
Intended use: Forestry wildlife defence, personal sport shooting. Must be 12-gauge, short barrel/overall length. A stock is preferred, as an shockwave style raptor grip may prove risky/unwieldy for follow up shots during a charging wildlife encounter? Any relevant discussion is welcome!

Hey,

Thanks for letting me know. Will look into it.
Did some more research about shorter overall lengths.
Found some great alternatives:
Mossberg 590 SPX #50696
https://www.mossberg.com/590-spx-50696.html
Shorter overall length, pistol grip. No parkerized or heavy walled barrel though.

Mossberg 590 – THUNDER RANCH #52145
https://www.mossberg.com/590-thunder-ranch.html
Breached barrel is cool but unnecessary. Shorter LOP, slightly longer barrel/overall length. Much cheaper, yet keeps 590 quality, also Thunder Ranch is boss.

Hopefully, these 2 models are more readily available.

Thanks again!
 
The 14" (actually 14-3/8") 590 Mossberg Shockwave series of shotguns have the same heavy wall barrel that the 590A1 have, just only in Cylinder bore, with bead sight configuration, no Ghost ring sights available.

The only other real difference is the 590A1 has a metal Trigger housing vs the 590 plastic one. There have been literally millions of mossberg 500/590s sold with a plastic trigger housing and it really isn't a weak link, Obviously metal one is ultimately stronger / better but IMHO probably for 95% of users unnecessary.

I have one of those "class 3 NFA" 590A1 and it is awesome with a modified choke barrel and factory soldered on crooked front sight post:rolleyes:
If you can find one for a reasonable price you cant go wrong with that choice.

Or you can get a 14" Shockwave, available in many configurations, SPX with the cool barrel shroud but crappy shell holder picrail thing, FDE ones, Silver ones, wooden grip, or regular style. Then $150 Magpul Butt stock and maybe a red dot mount from Tacord or S&J Hardware and you have an excellent manueverable, reliable shotgun for almost any scenario.

Currently Reliable Gun, among other Site sponsors have various options in stock:

I have a shockwave with the magpul stock (I also have the stock in the photo on OP's link). My biggest complaint about the shockwave is that it shoots about 1.5' high at 20m. Really tough to aim. One of these days I'm going to put my Burris fast fire on it and be done with it. Otherwise, love the gun.
 
Wow thanks for all the info!
Will adding a magpul stock on a shockwave adversely affect the buffer spring/recoil mechanism? Possibly causing a misfeed during recocking? I know this makes the shotgun more modular, but more parts = more chance for fault/break, less reliability?
The KG Armoury right outside Prince George has the exact set up you describe in coyote brown cerakote. I refrained from buying it in the spur of the moment. It’s only about an inch or so longer than the class 3.
Also..I found something very unique/strange. A supposed 590A1 with an M-Lock Forend, FLEX stock/grip, ghost sights like the class 3, 18.5 barrel. I will ask the overall length to confirm the claim by the seller that this particular one is “an American law enforcement overrun. Less than 100 units were imported into Canada”. They are asking close to $1200! Who knows how many rounds and bumps it has seen in service?! However it would be the only 590A1 with a short adjustable stock! It’s definitely possible some were made custom for law enforcement…

It’s only about an inch or so longer than the class 3. The Magpul stock adjusts length of pull (LOP) and therefore overall length; an overall length with an LOP that doesn't fit is meaningless.

There will be plenty of factory new 18.5" 590A1 with ghost ring sights for sale in stores if you have patience.

Hey, I looked into that overrun 590A1, and it’s not the short FLEX system.
Yeah, I’ll definitely wait out and keep looking around for something more reasonable.
Update!!: I have found a reliable US based supplier who has the class 3! :)
Their stock is quite extensive, my two options now moving forward are the 590a1 class iii vs 590 spx. Both are similarly well priced, maybe ~$100 difference between.
Thoughts? The milspec reliability could be worth it, but the flex system is shorter and provides more tactical handling…thoughts on the effectiveness of the extra shells on the stock during a wildlife encounter?

You won't find any reliability in one 590 versus another, the core gun is the same. You're looking at the features, and just have to pick what you like/get a deal on.

Once you've got the gun with the sights you want, you can change all that other ####. And I'd suggest velcro shell carrier.
 
I find the extra shell holder built in to the stock not easy to use especially if a bear was charging at me. Any type of saddle mount mount on the stock or receiver would be better. My point is I would not buy this specifically for the stock. The A1 is nice because you can use it as a pry bar and it might still shoot if you run your tank over it but otherwise the regular 590s are more nimble and handy.
 
There have been 3 in the EE in the last week. Not too hard to find. At one point they were, not anymore. Pretty common to find new or like new ones on the EE regularly. I have one and a beater version to toss around quadding and such. Both 14". I love mossy 590s and 590A1s.
 
There's no reliability difference between any stock I've used. The gun functions the same.

The only thing I like about the "speed feed" stock is that I can keep a couple varieties of shells on the gun, ready to go in the safe. Don't need to worry about finding the box in a hurry.
 
Thanks for the tips everyone. I see you have a nice pistol grip there. Do you have to adjust your grip/move ur eyes to the trigger mechanism in order to engage the slide lock/safety this way? It may cause a loss in precious time compared to no pistol grip, where the slide lock and safety are already in a natural nearby position. Thanks in advance!
