Difference between 590SP and 590A1

[jpatterson]

I have been looking at a Mossy 590A1 lately and noticed that I can get a 590SP for about 80$ cheaper. I have seen on other sites that they are basically the same thing, but I figured I would extend this question to you shotgun nuts that would probably know for sure.
So, is the 590A1 any different than an SP?
Thanks!

590A1 Has a heavy wall bbl and metal trigger guard and safety. It has 590A1 engraved in large letter on the left side of the receiver. It is a heavy shotgun for military use.

590SP standard bbl, plastic guard & safety. Lighter weight

That is the basics.

Keep in mind that the "original" 590SP isn't a light duty shotgun, it's just that the 590A1 is "even heavier".

The 590A1 with 20" barrel is really heavy. There is no real advantage to the heavier barrel. If you get a 590A1, you should consider the 18.5" version.

What’s really funny is that some of our boys overseas are using Mossberg 500A 6 shot (Persuader) that was bought at Wal-Mart. When and if the polymer parts break, the armory replaces it with the aluminum parts.

We have the M500. It's a parkerized 18 inch barrel, 5+1 capacity, and says Mossberg Model 500 on the receiver. Bead sight.
MY unit has six of them.

we got 7 of them on my ship stamped M-500MILS. 5+1 and an 18" barrel.

The 500 MilsGun is like the 590A1 with 18.5" bbl. They both have the same mag tube setup.
