About This Firearm
The Mossberg 590 is a synthetic-stocked pump-action 12 gauge built for home defense. It has an MSRP of $592. It holds seven rounds, three more than a Remington 870 Express, in a magazine tube that ends in a screw-off cap at the muzzle.
The gun arrives with a bead front sight, a cylinder bore with no choke threads, matte blue metal and a black synthetic stock. The receiver is drilled and tapped, so a ghost ring set, a rail or a side saddle goes on with a screwdriver and no gunsmith. Nothing on the stock adjusts and the length of pull is fixed. The safety is the sliding button on the top tang that runs across Mossberg's pump line, reachable by either thumb with no parts changed.
If you're cross-shopping, the Mossberg 590A1 has an MSRP of $910 and holds nine rounds behind a 20-inch heavy-walled barrel, with ghost rings, a metal trigger guard and a metal safety button, at 41.75 inches. A Remington 870 Express has an MSRP of $540 and a steel receiver that brings it to 120.0 oz, 19.2 oz over this gun, and it holds four rounds with a cross-bolt safety behind the trigger guard.

Strengths & Limitations
- Mossberg has the 500, 590 and 590A1 passing U.S. Armed Services Mil Spec 3443E requirements.
- Non-binding twin action bars, positive steel-to-steel lockup, an anti-jam elevator and dual extractors are shared with the rest of the 500 family, so parts and gunsmithing knowledge are everywhere.
- The anodized aluminum receiver is where the weight saving over a steel-framed pump comes from, and the lockup is still steel on steel.
- The cylinder bore has no threads, so the pattern cannot be tightened without a second barrel.
- Nothing on the stock adjusts, so a smaller shooter or a winter coat means buying furniture.
- There is less mass here to soak up a three-inch magnum, and the 590A1 weighs 15.2 oz more.

12 Gauge Ballistics →Frequently Asked Questions
What shells does it hold seven of?
Standard-length shells. The chamber takes three-inch loads as well, and running those drops the tube by one.
What does the screw-off cap on the magazine do?
It opens the front of the tube so the spring and follower come out for cleaning, with the rest of the gun left together.
Is the barrel heavy-walled like the 590A1's?
No. The heavy wall, the metal trigger guard and the metal safety button are the 590A1's Mil Spec features, and this gun uses the standard barrel and polymer parts.
