From this article about newcomers to the shotgun market:
Mossberg | 590M Standoff

Specifications
Gauge: 12; 2¾-inch chamber
Magazine Capacity: 10 rounds
Barrel Length: 14.375 inches
Overall Length: 27 inches
Weight: 6 pounds, 5 ounces
MSRP: $1,050
Apart from my distaste for the sawn-off buttstock, I have to say I think this might be a leeeeetle too much — because 10 rounds of 12ga ammo is going to ad more than a few ounces to the 6.5lbs of the gun.
Speaking for myself, if I had to pick one of the guns in the above article, I’d rather go with the
Heritage | Coachwhip

Specifications
Gauge: 12; 3-inch chambers
Capacity: 2 rounds
Barrel Length: 18.5 inches
Overall Length: 35.43 inches
Weight: 6 pounds, 12 ounces
MSRP: $984.99
Yeah, it’s actually heavier than the Mossberg above — but that extra weight comes from the longer barrels — which is where it should be, to help with recoil and accuracy. And it looks lovely, where as the mag-fed Mossberg… ’nuff said.

And the rest of the guns listed… meh.
That said, if I were in the market for a self-defense pump shottie, it is and always will be the peerless Mossberg 590 Mariner:

Full stock, 20″ barrel, 8 rounds in the mag (same number as in my 1911, FYI), indestructible finish… pretty much all one might need, methinks. One day I might sell one of my spare guns to buy this one. If I had a spare gun to sell, that is.

Feel free to argue in Comments, as always.
For a lifetime, multi-generational piece, you are spot on. You cannot beat the Mariner. And no ghost rings, gewgaws and gimcracks. Just a SIMPLE sling and a Big Dot front sight, that’s it.
The Big Dot epoxies right on top of the existing bead. All you need.

And don’t forget the Rob Haught push/pull technique. No pussified whining about recoil. My son gleefully shot 00-buck in it when he was about 10 years old and all of 110 pounds once he learned it. It works.

Didn’t pick up the para breaks, sorry. The comment software here is wonky.
Screw all that tac/gizmo stuff. Gimme that coach gun at a $500 price point and take my cash. Wanna!
I want that coach gun too, just because.
I’m presently “shopping” for a 12 ga autoloader, any “name” brand.
Must have a box mag, lightly used or new.
I will strip it down to the gutz and build it back to my own specifications using the best parts available. I’ve done this with 3 other guns in the past 5 years, including a Remington 870 Marine Magnum.
I have a police turn in Mossberg 500 with a side saddle for more ammo, ghost ring sights and some sort of rail up front if I want to mount a flashlight. I like the Mossberg design and ambidextrous safety. The detachable magazine on a shotgun does look appealing but the balance and weight just might be too much of a disadvantage for me.
MSRP for that Mossberg is nearly $900. I bought my Mossberg Maverick with both an 18″ and 28″ barrel for only $200. Seems like only yesterday though that was back in 1992.
Mariner that is..
You can do a similar gun on the cheap. I found a used Mossberg 500 used at a shop for like $190. The short barrel was $80. It has a wood stock, of course, and is blued rather than stainless.
But it’ll get the job done.
That 590M Standoff looks like it was designed for one primary purpose: trigger the hoplophobes into such a pearl-clutching frenzy that they all succumb to massive brain aneurysms.
That would be my guess too.
A friend has a roadside stand, and is looking for an “other weapon” for when he closes at the end-of-day:
When I showed him that Heritage Coachwhip, he just said that would really be handy if the bbl’s were cut back to about 8-9″ and it had a pistol-like stock and could be carried in a leg-holster as he needed both hands while closing down his stand.
Is his name Johnny Yuma? lol
No, but he has his autograph – framed, on the back wall.
Have owned my Mossberg 500 since around 1980. Like the tang safety, however it does not play well pistol grip stocks. No, I have no desire for a pistol grip stock on any shotgun. Nice to see that Mossberg finally came up with a rotary safety.
My front line shotgun is a Benelli M1 Super 90 that I have also owned for decades. Reload rides in a bandoleer/belt that hangs next to it. I just grab the bandoleer and sling it over my head and shoulder. It will hold 25 rounds, but that is waaay too heavy. I load it with 10.
S&W 1200 police/riot gun. Folding full-length stock with pistol grip. And loaded with buck and ball. Ouch.
But I’m not really a shotgun guy. No, the “if I have to shoot you in my house” gun is an AR chambered in .300 Blackout, subsonic and suppressed. And amazingly quiet.
I have a Wingmaster 870 18.5″ barrel and extended ammo tube with a birdshead grip that is the bedroom gun. I use a 65mm length shell and I can get 7 shells in the tube. I have a well used Stevens 311 double as a hunting shotgun.
I had a Mossberg 500 and did not like the safety location. I also had a Browning semi-auto. I found that having another shot on hand tended to cause me to not take enough time aiming.
