It's Mossberg's 590 designed specifically to function reliably with the shorty shells, thus allowing twice the magazine capacity. This mag can hold 9 on this 18.5" barrel model. That's as much as 10 rounds onboard.



My fud gun club doesn't allow buckshot, and you can only use bird shot on clays at the skeet and trap range. I shot at the rifle range, which meant I could only shoot slugs. The recoil with the shorty slugs felt about like a .30-30 out of a 94. Not bad at all.

This particular model only has a bead front sight and no rear sight. This off-hand, standing, five shot group was from 25 yards.



I imagine with practice, I can do better with a bead sight shotgun but, regarding group size, this seems good enough for government work, other than the fact that I was shooting way high.

I was just shouldering it, and putting the bead on the center, which I've read is the way shotgunning is done, vs rifle shooting. I guess I need to bring the bead down to just over the top of the receiver, though, if I want to bring the group to point of aim, or just position the bead lower than I want to hit.

Function was flawless.

It looks like that will do the job.

Just aim for the belt buckle, right?

Does it come with screw in chokes? What does the ammo cost?

Not this model. It's a cylinder bore.

Ammo cost is the same as 2 3/4" shot shells. Federal makes No. 8 target and small game, No. 4 buck, 00 buck, and slugs.

Always been an 870 fan for tactical shotguns but nothing at all wrong with the 590 for defense use. That will get the job done.

Maybe I'm missing it but it doesn't look like any come with choke tubes?

All I know is that mine doesn't.

I assume 2 3/4" work fine as well?

Yep, and 3".

I have one with 20” barrel and it has choke tubes( cylinder bore, improved, and full). I’ve been too busy to shoot it yet. Maybe Sunday

You have the S Model, too? You acquire any shorty shells for it?

Yes, 590s. I found some shells at the firearms depot. The model is 51604

XS makes a tall tritium front sight that will bring hose slugs down.

That's a definite thought. Thanks.

Would you put a reddot on it?
