Mossberg 590 Shockwave 20 Ga
OK not sure if this is any more than a range toy or something I’ve wanted since Terminator, but found one and decided before the ATF lose their mind I’d get one in. 20 Ga is a bonus as the ammo can be found for somewhat reasonable and it is lighter. I’m not going to brace - just going to put a Pachmeyr slip on grip and a sling plus side saddle for shells. Hickock seemed to like his, and many others like - so no real purpose but also have 250 rounds of #4 lead shot shells inbound from SGAMMO and some #3 buck - the buckshot is too expensive but picked up a few shells. Everything else is somewhat close to pre-COVID prices. Will post pics once in - arrives at FFL tomorrow.

It’s s a “firearm” neither long gun nor pistol...so figured closest match was pistol forum. So confused Wink

I have the 12 gauge version, purchased from Palmetto when the price was too good to pass up.

It would be better with a shoulder stock, even a reduced length of pull body armor version, but that would require SBR'ing what's really a loophole AOW shotgun.

Be sure to spend some time patterning it to see what it will actually do; accurate fire isn't as easy as one might think. It's very controllable. It can be aimed if held at eye level, but is best done against sling tension.

The forend strap is there for a reason; don't slip off or let your grip go past the forend.

Otherwise, it's a mossberg; it will last forever and it's about as reliable as they come.

Put a buffer tube adapter on it with an SBA4 brace. I use the MESA Tactical adapter, but Tacstar is OK and less expensive. The SB kit is the cheapest but it has a funny angle to it. The SBA4 is more solid than the SBA3 so it is preferred, especially for a 12 gauge.

With the buffer tube, total length is still over 26", and it doesn't have a stock so it's still a "firearm". But if you put a side folder on it (buffer tube folder or a 1913 back end, then it will be less than 26" and turn into an AOW (I think).

Next up is a Streamlight Racker forend which has it's own safety strap.

I picked up two last fall when they were dirt cheap, a 12 ga marine coat and a 20 ga black. I auctioned off the 12 last month. I like it as is, perfect in the event I need to clear my hallway.

Another case of would of - could of - should of. PSA price for the 20g was $279 + S/H at one point, IIRC. Frown

I've had the 12ga for a while now; as long as I'm not having another insanity-driven episode and loading 3" magnum slugs it's been an ideal defensive weapon for me. I mounted a pressure-pad activated laser on it and only sight with that method, or without using the laser, just shoot instinctively at hip level. It's not that hard to find the target with the Shockwave with either method; the only difference is that I can reach out farther with the laser. Besides I've zero desire to go against the conditions in ATF's determination/"approval" letter that Mossberg provided a copy of with the gun. No brace for me.

Regardless...shot shells out of a relatively short smoothbore barrel; no precision sighting needed.

FWIW, I have the Rem TAC14 analog, and without a brace was able to pass our state's LE qual course, with the exception of the optional 25 yard slug stage which I did not attempt. The platform has much more potential for accuracy than given credit for.

I have a 20 gauge Shockwave, no mods or anything, just plain stock. Spent time shooting slugs at my local indoor club to get the hang of it, then spent some time at my friends ranch shooting #4 Buckshot. Once one figures out a holding position and aiming, it is a hoot to shoot.

Mine fits perfectly in a special hiding place at my house for close encounters.

I too have the 12 gauge version with the "mini-shell" adapter. Gives me 8+1 rounds of Buck or slugs (I have mini-shells of both). I put the SB Brace on mine.

I was intrigued by the Shockwaves when they came out. LGS price of $399 quelled my interest. About two years ago, another LGS had the 20 gauge NIB for $199 so I took one home. Definitely a learning curve but I like it.

I’m not a shotgun guy so please forgive the perhaps stupid question. I’ve seen this before, what is the purpose of the first round (maybe last?) in side-saddle being reversed from other shells?

I think the reason that they did it in the picture is for hand clearance with the loading/ejection port and the forend.

In my side carriers, all the founds point down.

Christmas 2019 a local shop was selling them for $225 NIB. They had about 50 in stock. I regret not getting one Frown

Remember seeing article in one of the old annuals from the 70s-80s of plainclothes cops with something similar used for witness protection details. As I recall intended use was well within 20 feet of intended targets and probably more like reach out and touch you.
