Mossberg 590A1 Retrograde Review: Is It Worth The Money?

by Travis Pike

August 17, 2021



In the annals of combat shotguns, very few stand out. We have the Benelli M4, the Winchester 1897, the classic Coach gun, and of course, the Mossberg 590A1 series.

The Mossberg shotguns are the only pump shotguns who’ve passed the Army’s 3443 SG torture test, and today we are reviewing the Mossberg 590A1, but not just the standard 590A1 we got out hands on the 590A1 Retrograde.

This pump-action powerhouse was created through hot demand by the US military.

Mossberg 590A1 Specs

  • Cartridge 12 Gauge (2.75 to 3 inches)
  • Capacity 8 + 1
  • Barrel Length 20 inches
  • Overall Length 41 inches
  • Weight 7 pounds
  • Length of Pull 13.87 inches

I have a two-part answer to this question. First, let’s address the point of the 590A1 as a shotgun, then we’ll talk about the Retrograde series. The 590A1 is the combination of features demanded by the United States military for their pump-action shotgun.

The 590A1 spares no expense and features a heavy-walled barrel, a metal trigger group, a bayonet lug, and most models wear ghost ring sights. As a pump-action shotgun, these are as tough and as reliable as it gets. For the average civilian, this is a home defense shotgun through and through.

The Retrograde series came to be because Retro is currently the ‘In’ thing in the firearms industry. From Retro AR15s to Colt bringing back the snake guns. Retro is cool, and Mossberg released four Retrograde shotguns that wear wood furniture and a variety of finishes and features.

The 590A1 variant features a heat shield, ghost ring sights, and a parkerized finish. The Retrograde design mixed old-school looks with modern capability. The Retrograde series delivers a unique look that I can’t help but appreciate. As cool as Picatinny rails and optics can be, there is just something cool about wood and steel.

There are two capacity variants of note when it comes to this pump-action.

Mossberg 590A1 Retrograde – Our Take

This big heavy beast of a gun certainly feels hefty when loaded down with eight rounds of 12 gauge buckshot. Mossberg’s heavy-walled barrel, long magazine tube, and heat shield make the gun feel a little off-balance with a front-heavy feeling.

This hefty feeling turns out to be a double-edged sword. Sure it makes the gun feel unbalanced, but it also helps add weight and fight muzzle rise and recoil.

You can certainly feel the difference between the Mossberg 590A1 guns and standard shotguns in the muzzle rise department. You’ll also feel a difference as you start unloading and the tube magazine gets light.

Twelve gauge shotguns are always beasts in the recoil department, but proper mitigation techniques make it a good bit easier to handle. Push forward with your support hand and pull rearward with your firing hand, and you’ll mitigate recoil a good bit.

The corn cob style forend makes the gun easy to hold onto when pushing forward and controlling the gun. The rear wood stock is checkered as well for an easy grip. On the ergonomics side, Mossberg’s tang safety is mounted for easy access for both righties and lefties, and pump release is mounted for easy use with either hand as well.

The length of pull is 13.87 inches. This means two things. First, it’s perfect for me, which sounds great, but I’m six foot, five inches tall with ape length arms. What works for me doesn’t work for most people, and a length of pull of 13.87 inches is somewhat long for a lot of shooters, which sucks because you don’t want to replace the nice wood stock on the Retrograde series.

Getting on target is easy. The big rear ghost sight and high visibility orange sight provide an excellent mixture of speed and precision. Modern buckshot like Federal Flitecontrol very effectively extends the range of the classic scattergun, as do slugs. Sights like these allow you to take full advantage of slugs and modern buckshot.

As you’d imagine, this pump-action shotgun has zero issues in the reliability department. You can cycle all the 2.75 inch and 3-inch shells you could ever desire. High brass, low brass, cheap foreign stuff, and even cheaper Walmart birdshot. The Mossberg 590A1 even cycles Noble sport 2.5-inch shells, and with the right adapter, you can even shoot 1.75-inch shells.

Besides recoil from 3-inch magnum loads, the only pain this gun will cause is in your wallet. The Retrograde series demands a premium with an MSRP of $987 dollars. These things sell for well beyond MSRP as well, making them tough to obtain for fans of wood-equipped tactical shotguns.

Mossberg 590A1 Pros and Cons

  • Tight patterning
  • Excellent sights
  • Extremely Reliable
  • Endlessly customizable (But you won’t want to)
  • Sling ready
  • Expensive
  • Long LOP

Report Card


It’s a pump-action shotgun made by the kings of pump-action shotguns. It’s going to work for thousands of rounds, and won’t even think of failing.


It’s a shotgun with Ghost ring sights. It easily takes advantage of modern buckshot loads and slugs out to their utmost range.


The Mossberg 590A1 utilizes very ergonomic controls with the placement of the safety and pump release. The heavy-walled barrel adorned with a heat shield makes it a bit unbalanced, and the long for most LOP takes a point off.

The Mossberg 590A1 is typically an affordable shotgun for the features you get. The Retrograde series packs a premium, though. You won’t find a 590A1 for below MSRP, and the MSRPs between the Retrograde and a standard 590A1 is a difference of over 200 differences.


A 12 gauge shotgun isn’t for everyone. These often have rough recoil, and the pump-action requires training to ensure reliable feeding. However, once mastered, they are tough to beat.

  1. My Mossberg 590A1 doesn’t have a heat shield. I don’t believe my sights are Ghost Rings sights. In my Owners Manual it states that heat shields can’t be put on a shotguns with Ghost Rings.
    I like the weight and feel of this gun, the bayonet lug and that it meets military/ US Marine spec.
    It was purchased solely for home defense.
