Mossberg 590A1 Tactical Shotgun
In the world of law enforcement, military applications, and personal defense, the name Mossberg takes on a special meaning. Proponents of handguns, both pistols, and revolvers, acknowledge that no hand-held weapon has the intimidation factor, the firepower, and the situation-solving power of a shotgun.
Mossberg offers sporting models of many of its shotguns as well and remains a strong competitor on the waterfowl and upland game bird markets, but in tactical situations, they are a leader, and the 590A1 is a premier self-defense shotgun.
Available in a dozen different models, with magazine capacities of six to nine rounds of 12-gauge shells, this is a formidable pump shotgun with a reputation that many other models can only dream of obtaining.
The 590A1 is only available in 12-gauge, but in a situation where firepower is of the utmost importance, and recoil, gun weight, barrel length, and all the other parameters surrounding a shotgun take the back seat, this gun will deliver heavy rounds of buckshot or any other style of shot you prefer in three-inch shells.
While not quite as fast as a semi-automatic shotgun, many prefer the safety and control of a pump-action shotgun in desperate, self-defense situations.

Mossberg 590A1 9-Shot Traditional
The only appreciable difference between the 9-Shot Tactical and the 9-Shot Traditional versions of the Mossberg 590A1 is the stock. With a fixed stock, the length of pull is also a standard metric, not variable as it is with the six-position stock of the Tactical version.
The same Mossberg quality permeates this shotgun, identical three-inch chamber, eight-round magazine, and 20-inch barrel length all deliver the same specifications as the Tactical version, only in a traditional style. Many self-defense shotgun enthusiasts prefer the classic lines of a traditional stock and this one delivers on their passion.

Mossberg 590A1 7-Shot
If firepower and magazine capacity were the only metrics to worry about, you’d probably never see anyone even look at a 7-shot, pump-action shotgun, when a 9-shot variety was right next to it on the dealer’s shelf. The truth is that sometimes all those shells can be too much for some shooters.
A 3-inch, 12-gauge shell weighs almost two ounces. Multiply that by nine and you’re packing a little over an extra pound of weight above the listed weight of your shotgun when it’s empty. That seemingly small amount of added heft can make a big difference in performance. The 7-shot variety of the 590A1 arrives in an attractive Marinecote finish. It’s not stainless steel, but it performs in similar fashion at a reduced price, or a traditional Parkerized finish. It comes in three different sight varieties with other features identical.

Mossberg 590A1 Mariner 7-Shot

The Mariner features a six-round magazine, with one in the chamber for seven total shots. It is a preferred shotgun for military and law enforcement use in saltwater settings.
