New Mossberg 590a1

So I did a thing and bought this today from buds gunshop. It's model number is 50774 it has the 18.5" barrel 7+1 and is a 590a1. Unfortunately it was not under their qualified professionals list of discounted guns but they did price match me on another website.

I ditched my 870's once I tried a 590A1. I have exactly the same model and I think you'll be very pleased.

I like mine stripped to the bone...don't even have the rail on the slide. I put on a very simple tube-mounted light holder from GG&G, a light, and a sling. I like #1 buck.

Anybody wanna buy some Remy's?

The only things I'm probably going to go with are as follows.

1. GGG follower
2. Stock magazine spring. This should give +2.
3. Magpul moe forend
4. Magpul sga stock
5. Tacstar metal side saddle plate with industrial velcro cut to fit
6. Esstac 7 shot velcro side saddle
7. Limbsaver air tech pad
8. Inforce 500 lumen wmlx
9. Soe gear two point bungee sling.
10. Magpul sga front sling attachment

I like to mount the light on the magpul moe forend as with the wml and wmlx there is still plenty of room for the hand and you can naturally activate the flash light with your thumb if needed while pumping the action.

I found that the Black water 590A1 I purchased needed nothing more than a wooden stock and a Tritium blade for the front sight. I already had the M-9 Bayonet.

Now that's the most technical instruction on tactical shotguns I've ever read. It definitely leaves no room for misinterpretation. Might I ask what it is that makes an inch and a half so undesirable?

For me they are harder to manipulate when getting in and out of vehicles and clearing rooms. Plus they feel front heavy as hell.

If you are in and out of a vehicle alot like I am and you have to clear a room or building it's a real pain in the ass with a 20" weapon. It's precisely why I don't own a rifle over 16.5".

I'm surprised that you don't have an LEO length shotgun?
Wouldn't the 11 inched barrel of an AR be preferred?

We use 18.5" mossberg 500 tactical persuaders at work. What length does everyone else use? We also use 18.5" remington 870s.

No we use 16" rifles at work. I don't know of any departments around here locally that use 11" ar unless they are like swat teams with supressor .300 blk.

We have no weapons with over 18.5" barrels. Some of the tactical team members may but front line folks don't.

Many of US have gone beyond using shotguns at work. But here is a quick list of Government issued shotguns: https://en.wikipedia.org/wiki/List_of_combat_shotguns

Perhaps it's only the largest of Departments that issue Class III LEO Firearms. Cost is always a consideration.

Ordered my ggg follower yesterday for my 590a1. I also ordered a red delrin type 3 follower from S&J for my mossberg 500

Every way you slice it, the Mossberg is a better gun than the 870...speaking of combat shotguns. As sporting shotguns, I think most anyone would rather have the Remington, and I wouldn't blame them. As wonderful as the 870 is, it is inflicted with a critical flaw for a combat shotgun, the short stroke that will lock the action and take the gun out of action. The Mossberg WILL NOT do that, because it's basically a simplified/somewhat improved copy of the High Standard Flight King...which is itself, a copy of the old Remington M31; a shotgun Remington should have never discontinued. And the HSFK/Rem31's action is BY FAR the smoothest functioning pump shotgun I've ever seen, and they are absolutely, utterly reliable. So Mossberg was very wise when they chose their starting point for the 500 series.

The 500 series took the M31/HSFK action and modified the locking mechanism in a way that would accommodate a removable barrel. In doing so, they completely killed the smoothness of the action, but gained the removable barrel feature; and of course, kept all the wonderful reliability.

Funny, but Remington made the model 31 when they abandoned another amazing design, the M17 which Ithaca then took and made the model 37.

Now from a sales standpoint, one can never fault Remington for dumping two of the greatest pump shotguns ever made, because the 870 went on to be the best selling shotgun in the history of firearms; and it's hard to fault that. And as a bird gun, the 870 is just outstanding.

But from a technical standpoint, both the M17 and M31 are just leaps and bounds better than the 870.

Me personally, for a combat shotgun I'm a Winchester '97 kind of guy...who is currently Winchester '97-less. So filling in is a 20 bore Remington Model 11; another wonderful classic.

GunGeek, in the world of combat shotguns there are certainties that must be acknowledged. First, (the 590a1 pump in particular) the outstanding Benelli semi-automatic shotgun is inherently better suited than any manually cycled pump while in the prone position. Second, any manually cycled pump is better able to digest a larger difference in rounds than a gas dependent cycling semi-auto. Third, neither system can compare to a Full-Automatic system when attached to a remotely operated vehicle.

Now none of this really applies to a game hunting field shotgun, as there still hasn't been an advancement that allows faster selection between chokes while hunting/wing shooting game afield than a double triggered double barreled shotgun of either over/under or side by side design. So when it comes to classic Wing shooting field shotguns, the double triggered double barrel is still the epitome of the artisans craft, while the pump is classic in field versatility, and the semiautomatic is reaching new heights on the battlefield. Perhaps more than just my humble opinion?

Cost IS an issue, but there are other factors, too. I'm sure you (and about everyone else on this board probably) have heard the stories about agencies that have "lost" or had "stolen" Class III firearms. Usually this is the full-auto type that gets everyone's attention, but even having an SBR or 14" barreled shotgun come up missing can be more than a little embarrassing.

I know, any firearm, even the street legal ones, that comes up missing from a cop shop is bad news. But the full auto or shorter-than-allowed-most- of-us-barreled ones really bring some real heat.

Welp,

She came in to the ffl today. I went and checked her out. Sights straight, action smooth, fed and ejected reliably with snap caps, the safety worked. However the whole thing was covered in what looked like bearing grease. I thought cosmolined sks's were bad but damn mossberg. It came with the choke tube wrench for my accu choke. I promptly packed it all back up and drove 30 miles to the FedEx hub and dropped her off to go to aimpro tactical in conifer colorado for some custom work.

Accu choke on a thick walled 590A1?

AIMPRO Tactical 185? http://aimprotactical.com/aimpro_tac...p_packages.htm

Probably better that you sent it packing. JMHO.
