I've had a Mossberg 500 "Combo Gun" for some time now, and recently picked up a 590 A-1 Mil-Spec. I thought it would be helpful to do a comparision of the features / price / and value of both guns because while both may appear similar, there are a few differences worth pointing out.

First off I'd like to point out that isn't rust you're seeing in the pics. It is just very poor color saturation from my crappy Sony Cybershot camera. The "striped" appearance of the Parkerizing on the 590 are oil absorption marks that transferred from the case I had it in.

PRICE

The Mossberg 500 "Combo-Gun", as it is referred to by several of the big box stores that sell it today, runs right around the $249.00 to $299.00 range. The 590 A-1 Mil-Spec runs, (as you see it configured), around $460.00 to $480.00. About $160.00 to $180.00 more.

FEATURES

The 500 "Combo" comes with a standard anodized receiver and 2 gloss blued barrels. The barrel you see mounted to the weapon is the 18" cylinder bore with a standard brass bead front sight that is threaded into the barrel. The gun also comes with a 28" Vented Rib standard field barrel that has a fixed Modified Choke. It does not accept screw in choke tubes. Mossberg does sell aftermarket barrels for this gun that do have them. It has the standard synthetic field stock and forend. The gun has a standard 5 + 1 capacity. Both barrels have 3" chambers.

The 590 A-1 Mil-Spec has a parkerized finish on all exposed parts. Barrel, receiver, and bolt, as well as the magazine tube are all Parkerized. The barrel is a 20" cylinder bore with a single brass bead threaded front sight. The magazine tube hold 8 rounds for a 8 + 1 capacity. It also has a 3" chamber. Other features of the 590 A-1 Mil-Spec Model are a bayonet lug that is threaded to accept a front sling swivel that comes with the gun, a heavy walled barrel, a metal safety button and trigger group, (the safety switch and trigger group on the 500 are plastic).

The 590 A-1 Mil-Spec also comes in an all but limitless amount of stock configurations. Standard, collapsible, as well as Speed Feed and others are offered. There is also the 590 SPX Model that comes complete with the Ontario Knife M-9 Bayonet.

Another feature of the 590 A-1 Mil-Spec Models are the dual barrel / magazine tube attachment points. As the photographs show, the 500 Models are attached by a single ring at the end of the magazine tube. The 590 A-1 Mil-Spec has a dual attachment system with two rings that are heavily brazed to the barrel. The barrel also attaches a bit differently on the 590. The magazine cap is completely removed, then the barrel removed. This is much like a Remington 870 in that regard. On the 500 the magazine cap does not completely come off.

The actions on both guns, while not totally identical, are very similar. The manual states that barrels and internal parts will not interchange between the 500 / 535 / 590 Models. I haven't tested this, so I'll take Mossbergs word on it.

OVERALL VIEW

Both of these guns exhibit excellent value and quality for the price. Both are made in the USA. If a person is looking for the most for his money, the 500 "Combo" is pretty hard to beat. It offers very good value for the dollar. Especially considering you get 2 barrels with the package. I've had around 1,500 rounds through mine total so far, and have not had a single issue or problem. These loads were a combination of low brass target loads, heavy 3" Magnums, as well as Buckshot and rifled slugs. It ate them all with zero issues. The 590 Mil-Spec I just received this past Friday, so I have not been able to evaluate it's performance. Hopefully I'll get out to the range next week to run it through it's paces.

If a shooter is looking for a well built, solid home self defense weapon, the 590 A-1 Mil-Spec would be a pretty difficult gun to beat. It was the only pump action, combat shotgun tested by the military that met Mil-Spec requirement Mil S-3443 which consisted of 3,000 rounds of Magnum buckshot with the gun being fully operational afterward.

The other guns in it's class are more expensive when similarly configured. It appears to be a gun that can hold up to a lot of rugged use. I think it would be a hard gun to beat in the role of a home self defense shotgun. Which is better? At this point having not yet run the 590 A-1 Mil-Spec through it's paces as of yet, I would say based on features and price, the 500 "Combo" is the better buy, while the 590 A-1 Mil-Spec is the better gun. Either way I doubt you could go wrong with either.

Also note that the Mossberg 500 combo sports a foregrip/pump from a Maverick 88. This is why the combo is so cheap. If you ever want to upgrade the foregrip/surefire, you will need to buy the whole action tube assembly which runs ~40-60 bucks depending on the length you choose. Though not common, I have seen where the foregrip breaks right where the rails are pinned. Just an FYI for those that are considering the combo.

It was not an easy choice for me between the Mossberg 590a1 and the Benelli Supernova Tactical.

LOVE the 590a1 and I think if you want a durable finished gun, one where you can easily clean the magazine tube, have high capacity (can't increase M500) then get the 590a1. Spend the extra money if you intend to shoot it alot. I took my 500 out twice and I was regretting not saving one more month for the 590a1.

One other feature I forgot to mention on the 590 A-1 Mil-Spec, is that it is equipped with dual extractors. It is all but impossible to get a shell stuck in it.

Will do. I'm hoping to get out to the range this week.

The only downside with 590A1 is the weight due to heavy barrel, it is probably one of the heaviest pump action around.

Three point sling is recommended for long time carry.

I hear this a lot. According to Mossberg's own spec chart, the 590 A-1 weighs the same, or in some cases, even less than the various models of the 500.

i called about 70% of dealers around the bay area today to get the 590a1 i want and nobody has it. the worst part is that its a special order and their suppliers dont have a clue on availability. some told me it might take a couple weeks to a few months so they can get em and even then they aren't sure..... and i tried two months ago also.....wanted catalog #51663. can you change the mag tube from a 5+1 to the longer 8+1? if not im considering that combo

Nice write up; here's a couple things to add from experience with my 590 (mine's not a 590a1 though it is parked)

If considering the 590, my experience is that the ghost ring sight option is far better than a bead sight for slugs and buck. However, for some reason you cant get the ventilated handguard with the ghost ring sight optioned gun (I dont know why)it doesnt look like it would interfere, but I havent measured it yet.

The 590 (as opposed to 590A1) does not have the dual barrel clamp, nor the heavy barrel (I think) and it has a plastic trigger guard. Its a little cheaper too I think..

The speed feed stocks are nice (tacticool), but side saddles are more practical/usable (I have both!)

PRICE

The Mossberg 500 "Combo-Gun", as it is referred to by several of the big box stores that sell it today, runs right around the $249.00 to $299.00 range. The 590 A-1 Mil-Spec runs, (as you see it configured), around $460.00 to $480.00. About $160.00 to $180.00 more.



Does the price on this regularly go down to $249 or is that a rare occurrence? I'm in the market for this combo and want to know when I should pull the trigger.

Davidson's is currently showing 27 of them in stock in various configurations. 7 of them configured like mine, (51660). Just find a dealer near you who stocks from Davidson's, and you'll have your gun in 3 days or less, minus the waiting period from when you order it, if you're in California.

I'm not trying to start a Remington VS. Mossberg argument here. But with that said I like the Remington 870's, and have had one since the mid 70's, (Wingmaster). But I really prefer the Mossberg 500 or 590 Models for a home defense shotgun. I just think they are better suited for the task. I like the steel receiver of the 870, but I wish they would get away from that cheap, cheesy, stamped metal, double C-Clamp for attaching the barrel to the magazine tube. Especially on the Police Models. When you're paying that much for a self defense, Hi-Cap shotgun, it should have better manufacturing than that. If Mossberg can supply brazed, machined steel, double attachment points, a bayonet lug, and dual extractors for under $500.00, (590 A-1 Series), Remington should be able to for almost $200.00 more, (870 Police).

Here are a couple of videos of "Hickok 45" running a Mossberg 590 A-1 through it's paces. He does a good job on that gong at 200 yards with Foster Slugs, and only a bead sight. He also shows some of the guns features in detail.

Just picked up my 500 Persuader 8 shot from Big 5 last night. $299 deal ends this week! Going to order a light and a mesa tactical side saddle and that's it. Bought it for HD purpose mainly.

That's why I was asking about the $249 price. I was looking for any Big 5 coupons that work on firearms but there doesn't seem to be any floating around.

Any one have a line on any coupons that will work on firearms.....Google just turns up expired coupons

I bought the 590 spx with the heat shield and added the ghost ring sights. When I was shopping for it I found somewhere that Mossberg didn't offer ghost rings on the models with the heat shield because it's a little more difficult to get the heat shield off, over the front blade and testers were scratching up the finish on the barrel. They decided it would be a source of complaints and didn't produce that configuration. It's not a big deal. you just have to take 2 extra seconds and remove it with a little care.

Considering the $100 difference from the spx to the a1, if you're not taking it to war, the spx is great for 99% of the people .. the A1 just has the tacti-cool factor some people like.

Well I decided to head out to the desert today with the new Mossberg 590 A-1 and run it through itís paces. We got almost an inch of rain last night, so I knew it wouldnít be too dusty, thatís for sure. I brought along a hand trap and some clay targets, and a bunch of water filled jugs, cans, and some other stuff I had lying around to shoot at. I stopped at Cabelaís this morning and picked up another 100 rounds of the Rio, 00 Buckshot they had on sale for just $2.19 for a box of 5. I also had some Federal 3Ē 000 Magnum Buckshot loads, and about 50 slug loads. Some Winchester, Remington, and a few Federal.

Before we left I lubed the action up really good. I set up several water filled 2 liter bottles at about 30 feet, and filled the magazine with 3Ē rifled slugs. The gun ran through them flawlessly, vaporizing the bottles into nothing more than shredded plastic. The 3Ē Magnum 000 Buckshot loads did much the same. Recoil was stout, but it felt a bit less than the same loads run through my Mossberg 500 I brought along as well. I had a can of Miller Lite thatís been sitting in the fridge for months that I shook up real good, then smacked it with a 3Ē slug from about 25 feet away. It erupted like a can of shaving cream! It's amazing how accurate that single bead front sight is once you learn to settle into the same sight position every time.

My wife shot it with both the slugs and buckshot loads, but found the recoil to be a bit uncomfortable. I had a bunch of Trap loads I brought along, so I threw several clays for her, which she had no trouble breaking consistently. Tossing clay targets from a hand trap is like shooting fish in a barrel, when compared to shooting singles from the 16 yard line, but itís still enough of a challenge to do it with a cylinder bore riot gun.

I had some short pieces of 2 X 4ís I brought along, and sat them against a small hill. I shot them with 3Ē 000 buckshot, 2 ĺĒ 00 buckshot, as well as Trap loads, (1 1/8 ounce of #8ís loaded with 17.5 grains of Clays). From 6 to 8 feet away the buckshot had zero trouble chewing the 2 X 4ís in half. It didnít surprise me how much damage the Trap loads did from that distance either. They would have been extremely lethal at that close of a range. They chewed right through the wood like a spade drill. The 1-1/8th ounces of shot almost acting like a slug at that close of a distance.

Through all of this the gun performed flawlessly. It was amazing how slick the action became after about 200 rounds or so. It was very humid, so after cleaning up after ourselves we decided to call it a day. After we got home it was humid as hell out, so I set up a fan in the garage and gave both guns a good wet cleaning with clean Kerosene, cut with a little Hoppes #9. Both barrels got a good brushing until they were spotless. While shooting I tried not to heat them up too much. This greatly reduced the plastic fouling from the wads. Afterward I gave the actions a good blow dry with compressed air, and a good oiling. The 590 A-1ís action improved immensely after the cleaning and relubrication. Itís far smoother than I though it would get from just a bit of use. The Parkerizing can be quite ďgrittyĒ, and after you wear it off the high contact areas, it really smoothens thing up.

The only downside to the day was the high humidity from all the rain we got last night. But I canít complain. And the way itís shaping up, itís looking like weíre in for some more rain later today and tonight. We donít get much of it in these parts. All in all it was a good day, and I couldnít ask for a better performing gun than this new Mossberg 590 A-1 Mil-Spec!

Depends on you and the purpose of your shotgun. For me, yes.

I actually bought my combo with the intent to do BJs skeet/trap class but found out the 28in barrel does not have the optimal choke for that.

I now have to buy a replacement accuchoke barrel and hope someone buys my used 28" fixed choke.

Cabelas (http://www.cabelas.com/barrels-chokes-mossberg-replacement-shotgun-barrels-1.shtml) sells the 28in accuchoke barrel for $180.
