The Mossberg 95137 is a 5-round double-stack magazine for the 590M mag-fed pump shotgun, designed to work with 2.75" shells. If you run a 590M, this magazine represents a real shift in how modern shotgun magazines work. Mossberg engineered a double-stack design that keeps capacity high while actually shortening overall magazine length compared to traditional single-stack boxes—that means better gun balance, faster target transitions, and less fatigue when you're working through a course or hunting all day. The engineering here isn't flashy; it's just solid thinking about what makes a shotgun handle better in the field or on the range.
Build quality speaks to why this magazine belongs in a serious shooter's kit. The feed lips are hardened steel over-molded onto steel shell ramps, so they'll stand up to thousands of rounds without deforming. The magazine body is a proprietary self-lubricating polymer that resists corrosion and doesn't require babying. The spring is heavy-duty ASTM-A-228 music wire—the same spec you find in precision industrial applications—and the steel components wear a tough black oxide finish. A removable floor plate makes cleaning and maintenance straightforward, so you can keep the magazine running smoothly without taking it to a gunsmith.
If you're investing in the 590M platform, recognize that Mossberg built the magazine ecosystem to match. The 95137 works alongside 10, 15, and 20-round variants, so you can load your kit based on the mission. 5-round magazines excel for hunting, training with frequent reloads, or any scenario where capacity takes a back seat to portability and control. This is one of those parts that doesn't grab headlines but earns respect from people who actually shoot.

This magazine is designed for 2.75" shotshells only. Do not attempt to use 3" shells or other lengths; the magazine is engineered specifically for the shorter round.
Yes. Mossberg makes the 590M magazine system in 5, 10, 15, and 20-round versions, and they're all compatible with the same 590M shotgun platform. You can rotate between sizes depending on your shooting purpose—5-rounder for hunting or training, larger capacities for competitive or tactical work.
Double-stack geometry allows the magazine to hold the same or greater capacity in a shorter, slimmer package. This keeps your shotgun balanced and pointable, especially during transitions or when you're working through multiple targets. Shorter magazines also sit lower on the gun, improving overall handling and control compared to long single-stack boxes.
The removable floor plate makes field stripping simple—just unscrew the base and you can access the interior for inspection and cleaning. The self-lubricating polymer body resists corrosion, and the hardened steel feed lips don't require special treatment beyond wiping them clean. Avoid submerging in solvents for extended periods, and replace the spring if it loses tension after years of heavy use.
