I'm just wondering the pro/con of picking A1 over the regular 590. I heard weight and material might be different. Also how much cost difference should I expect?

Thanks for any tips!

Some will try to tell you the receiver is steel, it is not. The barrel has thicker walls giving it a little more weight. I would personally stick with the 590 if it is available to you.

The 590A1 has a heavier barrel, metal safety, and metal FCG housing. That's it. If those are important to you, then go that way. If not, you would be paying extra for stuff that you don't need. That call is up to you.
I like my 590A1, and it's stood up to quite a bit of abuse. I don't care for the plastic safeties on any weapon, and I liked the idea of the barrel and FCG being able to handle the occasional knock against a car door or whatever.

I have both...and paid $380 OTD for a brand new 590A1. If I had it to do all over again I would have just gotten the A1. It is built like a tank. The extra bit of weight from the heavy barrel tames full power buck and slug VERY nicely compared to the plain 590. I also prefer the parkerized finish and ghost ring sights for a HD/SD shotgun, which the A1 has. Metal safety and guard are better as well.

M24,

I did not think you could mount a heat shield on a 590 with ghost rings, how did you get yours to fit?

I also prefer the parkerized finish and ghost ring sights for a HD/SD shotgun, which the A1 has.

The standard 590 can be purchased with them too. 590s have been very difficult to come by in my area. I consider myself lucky to have a 590A (50663). Hefty enough that 2 3/4" 00 shells are easy for me to control. The plastic parts don't bother me; I've never heard of a trigger gaurd breaking under normal use. And I don't use the safety anyway (stored cruiser ready - loaded mag, empty chamber, hammer down, safety off).

JAD:
The plastic safety has been known to shift after a lot of use just from the recoil of firing. Granted, this usually occurs during classes, on departmental weapons, and after prolonged heavy use. So that may not be a concern for you. I keep all my shotguns in cruiser ready, so I'm not generally using a safety except when commanded to do so in a class or qual. I wanted the metal parts because it is a working shotgun and I wanted to minimize as much worry as possible.

About the shield, this is from one of my posts from a thread a little way down:
This is for the 590A1 with the heavy barrel. If you have the standard 590, it will be a lot easier and you probably won't have to do any fitting.
The handguard is the Mossberg stock handguard in park finish.
To start with I had to get two slightly smaller diameter and longer machine screws and nuts. Sorry, I don't remember exactly what size. I would have written it down if I had realized how many times I was going to have give out this info. Luckily they did have some already in tactical black. Make sure that that you don't get them too narrow, you want them to stay secure and not go TU on you. You also want them to be at least two and half to three inches long so you will have enough room to work with them and to make it easier to secure the nuts without having to try to apply a lot of leverage on the forward barrel ring.
To fit the guard on the barrel, you will need to rotate it slightly to the side (9 o'clock or 3 o'clock) and hold it parallel to the barrel. Slip the rear barrel ring over the barrel (you want to do this at a point where the rear barrel ring can slip over the narrower barrel diameter as it tapers towards the muzzle) and start sliding the guard to the rear toward it's final position. You might have to rotate the barrel back towards its normal orientation and position (top dead center) on the barrel as you slide it to the rear. The forward barrel band should be slipped over the barrel as it clears the front sight assembly. You may want to put some masking tape on the barrel to prevent scratches for this step as it might be a tight fit depending on your guard and barrel.
You will have to relieve some of the metal on the underside of the forward barrel band. This is the part with the two "ears" that come down and that the cross screws secure. This piece is spot-welded to the actual body of the shield, so be careful that you don't remove too much metal. You will have to test fit the guard as you go to see how much you need to take off.
You will also have to slightly extend/enlarge the cross-screw holes in the ears to give the cross-screws enough clearance below the barrel. I'm not talking about much, just a little.
You will have to do several trial fits to make sure that you don't take to much metal off of the guard. As you are fitting it, check the clearance of the cross-screw holes when the barrel is mounted to the receiver and with the handguard in its proper position. You will need to fit the screws through the forward barrel band to make sure that you can get the nuts on them. Do not trim the length of your cross screws yet.
Once you have the guard modified so that you can get the cross screws through the forward barrel ring, take it off. Apply some cold blue, Casey's touch up, Duracoat, or whatever. You just want to apply some protection to the exposed raw metal so that you don't get any corrosion under the guard.
Trim the plastic spacer that comes with the guard as directed in the instructions. As always, trim slightly oversized so that you can make a final fit to test for proper length and fitment of the spacer. It may be necessary to remove some material from the top or bottom surface of the spacer again depending on your barrel and guard.
Once you have the guard like you want it, install the guard and secure it with the cross screws. Now you can trim the length of the screws, and touch up the raw metal ends.
You now have the rare honor of what Mossy says you can't do and I've been doing for about seven years.

Awesome m24, thanks for the info. I've filed it under "possible future Mossie projects" for the time being.

As for the plastic safety, I hear I can always replace it with a metal one for dirt cheap, so I may do that in a few years. Doubt it'll be a problem, but I may do it for peace of mind.

If you go that way, I would highly recommend the Vang model. I did it on my SPX, and it is great. It is more of a teardrop shape, and sits a little higher than the stock version. It is even easier to disengage the safety with it.
