Just curious as to what the boards general consensus is of the Mossberg Shockwave value as the "go to " choice for home defense.
I received a 20g version for Christmas. Thinking of adding the 12g version to the collection.
Either one seems to be a solid choice for the home defense application.

Those things are only popular because they are used in movies IMHO. Have you shoot it yet?

How do you plan on aiming it?

A full size shotgun is a much better option.

There was a pretty good review on the 12ga in the September edition of Shooting Illustrated.

Crazy that it has a 14" barrel. It's basically a legal sawed off shotgun. Nice present

Yes, both my 20 and a friends 12 gauge. Not nearly as bad as a conventional pistol grip.

its a shotgun with a 14 inch smooth bore barrel. Not a whole lot of aiming involved, more of point and shoot.

i like the freedom of movement this provides vs conventional shotgun.



My thoughts are, maybe not the best for someone new to guns, but for some one with adequate training, including hip shooting. This is a very viable alternative for a bedside, home defense weapon.

I generally don't like shotguns for home defense. They have low ammo capacity, hard to reload, huge recoil, and if it's a pump it's difficult to cycle (esp for women).

My go to is my AR with a backup g19. Take a look at this article written by Kyle Lamb. He brings up a lot of good points about using a AR for home defense versus a shotgun and pistol.

I bought one three months ago and I love it. I got it for home defense. Mainly because I have narrow halls and I don’t want to lift the barrel to turn if I need. Remington has an 870 model as well.

Don’t shoot it with one hand though. It kicks too hard. Two hands from the hip.

Using Aguila's 1&3/4" minishells increases the capacity to nine total, with eight in the magazine & one in the chamber.

To use the minishells, you'll need to buy a OPSol mini-clip and mount it in the shell carrier. They're about $20.

It sounds like you've pretty much already made up your mind in that you like the "Shockwave" so my comments really are aimed at readers who're undecided.

Surely the shotgun is one of the best self defense guns. Although 12 gauge is generally preferred, a good argument can be made for the 20 gauge. Opinion seems split on whether to use pump or semi-auto. OTOH, although I don't claim to have read everything available on self defense, I don't recall seeing very many, if any, reputable experts who recommend always shooting a shotgun from the hip instead of the shoulder. Personally, I wouldn't have any use for the "Shockwave" unless nothing else was available. If a typical shotgun barrel is too long, use a handgun. If one insists on using a shotgun from the hip, one can still do that w/ a regular stock shotgun. I don't see where the pistol grip stock of the "Shockwave" has any advantages.

It's good you're experienced and skillful enough that you can shoot a shotgun adequately from the hip. I don't know about others, but I admit that I can't do that well enough to bet my life on it. I like Massad Ayoob's comments on aiming a shotgun:

"Owners should be aware that shotguns do not shoot a spread across an entire room when firing them for self-defense. Shotguns need to be carefully aimed the same as any other type of firearm when using them for self-defense purposes. A riot gun with an 18-20 inch open-choked cylinder barrel has a spread of approximately 1 inch for every yard of firing range. The spread across an 18 foot room will be 6 inches and the spread across 50 feet will be 16 inches. Practice with shotgun at firing ranges to determine what type of spread your shotgun has when fired."

If I was going to use the "Shockwave" for self defense, I'd mount a laser sight to the upper receiver. I don't keep up w/ LEO literature or training, but I'm someone here does and can answer my question: do police (and similar agencies) routinely use pistol grip only shotguns like the "Shockwave"?

This is worth the quick read. Its from the NRAfamily.org site.
One mans opinion changed from pure gimmick to at least useful in some situations.

I have a Serbu and a 12.5" 870. The Serbu stays on my nightstand and the 870 stays in the safe.

Have you shot anything comparable?

You bring up some good points, especially adding a light/laser. I don't have one for what it's worth. The design of the Shockwave integral birds head stock (not a pistol grip) allows for it & it's 14" barrel to be 26" long (overall length) and has been deemed a non-NFA gun.

I'm pretty sure if you removed the standard stock, and installed a pistol grip on a 870 with a 14" barrel, you would have created a NFA firearm. I think a 18" barrel would be the minimum you could go with for it to br legal. It's been awhile since I went thru this on a shotgun conversion, so I may be off a couple of inches. At least that's what she said,

Interesting read. OTOH, the author only said "recently, however, my opinion has evolved slightly..." Still not a ringing endorsement. I still prefer the simplicity of the just as effective full size shotgun. Whoever goes the route of the "Shockwave" certainly needs to practice w/ it.

Don't worry, I'm not going to be doing that either.

TigerOnTheHill has had the best advice so far. The Shockwave does nothing that a standard 18" shotgun with a stock can't do. Well, it may be handier for breaching doors but I don't know of anyone on this board who is active on a SWAT team.

I'm also with Tiger about shooting from the hip versus using something as simple as a bead on the end of the barrel. Shotguns don't just spray like in the movies so it makes little sense to put that must trust in the chance that you'll connect with your target. Do you see police agencies using stockless shotguns for self defense purposes? It may not determine your decision but should be an important data point.

Have you seen any tests as to the effectiveness of these shells? And again, do you see any enforcement agencies using them? You should have all the information you need.

If you want it for the "cool" factor I can understand, but I don't see this in any legitimate self defense scenario.

Uh maybe you haven't heard, but you just have to rack the slide and it scares off the bad guys.

From the link the OP provided:

"Aguilar offers the mini shells in #7.5 shot, slug, #1 & #4 buck.

Driven 1250fps, a 5/8oz of #4 buckshot delivers seven .24 caliber pellets that combine for roughly 875 ft-lbs of energy at the muzzle. That's more than twice the energy of a .45 ACP. Yet, because of its reduced payload, the Shockwave fully loaded with these shells produces about 10 ft-lbs of recoil energy compared to the 30 ft-lbs of a 2.75" #4 buck (1250fps, 1.5oz payload)fired from the same gun."

I've never shot these & don't know anyone who has, this is just what the author stated in the review.

That’s surprisingly more energy than I thought so I stand corrected on that piece of data.

As far as a stockless shotgun versus one with a stock, my comments stand.

That is very much a pistol grip, but you are correct the OAL of 26" (barrel length does not matter, just OAL) keeps it from being an NFA firearm with the possible exception of if you conceal carry it.

The minishells are fine for home defense. Their slug version is 385 grains moving at 1150-1200 fps.

That's more energy than pretty much any common home defense pistol caliber (over 3x the energy of a standard 9mm).
