Mossberg Special Purpose Model 500 Mariner 50273 3-inch 12 Gauge, $571

Read Gun Tests Rating and Recommendation

GUN TESTS GRADE: B+
The action of the pump was a little rough. The extended magazine provided increased firepower, but with the counterbalance of added weight and nose-heaviness. Performance with slugs, buckshot, and birdshot were stellar. Our corrosion test was uneventful - exactly what we wanted to see.

One of the big advantages the Mossberg held was its inclusion of a pistol-grip accessory in case the shooter wants to shoot a shorter overall package. This grip cuts the overall length of the shotgun by almost 10 inches, to 28.75 in. We fired several different loads into our zombie "attackers." They were uniformly devastated at short distances, so we have confidence in the gun as a fight-stopper.
We preferred the location of the Mossberg's action-release switch because it didn't require a grip change to activate. The thicker, smoother profile was better, too.
The other major upside to the Mossberg, besides its cheaper price, was the drilled and tapped receiver. It was easy to add a rail and a red dot or low-powered scope to shoot slugs accurately.
We didn't like the rounded shape of the Mossberg's forend.
