Mossberg 590M Mag-Fed Pump-Action 50205 12 Gauge

Read Gun Tests Rating and Recommendation

GUN TESTS GRADE: D
We liked the Mossberg when examining the piece in dry fire and based on the magazine design. The magazine does protrude more than the Remington, but it holds ten shells. The shotgun did not function as well as the Remington DM or the tube-feds. We would not buy this shotgun at this time.

Here's the shotgun loaded with a 10-round magazine. The piece was supplied with a single ten-rounder shown detached below.
Mossberg magazines come in a variety of lengths and specifications. The magazine heads are 3.5 inches long and 2.5 inches wide. The five-round magazine is 5.3 inches tall. The 10 round is 8.0 inches tall; the 15 round is 10.7 inches tall, and the 20 round is 12.6 inches tall.
We liked the Mossberg magazine jamming in the 590M. attachment itself, but we do not like the sharp-shouldered feed ramp inside the gun. The receiver of the Mossberg 590M has undergone considerable modification to accept magazines.
Of course, the higher-capacity Mossberg 590M magazine is taller than the Remington 870 DM magazine.
While it appeared durable, we experienced feed issues with the Mossberg magazine. The 590M suffered several malfunctions, perhaps 35%.
We experienced tie ups even while working it in dry-fire drills. Above are two instances of 2.75-inch shells jamming in the 590M.
