mossberg 590a1

The Mossberg 590A1 Tactical features MilSpec construction- the only pump-action shotgun to pass MilSpec 3443E; Parkerized or Marinecote finishes on heavy-walled barrels; metal trigger guard, M-Lok forend, and safety buttons.

Mossberg’s 590A1 shotgun is built for hard use. Featuring mil-spec construction, according to Mossberg, the 590A1 is the only pump-action shotgun to pass Mil-Spec 3443E and has been selected for duty by the U.S. Armed Forces. Select models feature Parkerized and Marinecote finishes; fixed, full-length, six-position adjustable, +4 Shell Holder, and Magpul buttstocks; and XS rail-mounted sights. The model I selected for this review features the Parkerized finish, a Ghost Ring adjustable rear sight, and a special M-LOK forearm. I’ll get into the details of those features in a minute, but first, let’s review some of the reasons a pump shotgun is a good choice for defense.


Almost every review you read about tactical shotguns talks about their versatility. That’s certainly true when you’re talking about the different types of ammunition that can be used in a tactical shotgun. For example, there are buckshot loads, slug loads, and specialty loads that really do fit a wide range of applications.

Other reasons cited by shooters always include testimonials about the utter reliability of a pump shotgun. According to more than one forensic technician, pump-action law enforcement shotguns rarely, if ever, malfunction.

A pump-action shotgun with an 18.5- to the 20-inch barrel is easy to handle in confined spaces, and it stores pretty easily even in a vehicle. Many of them weigh enough that felt recoil is manageable, but they aren’t so heavy that a defender with a slight build cannot shoot them comfortably.

And I would be remiss if I didn’t mention the pop-culture phenom centered on the pump gun’s intimidating sound when the action is worked. More than one lawman has referred to that as being one of the most “ominous” sounds a criminal can hear.
