Mossberg Model 590M 12ga 10 Round Shotgun Magazine Review

Meet the Mossberg Model 590M 12ga 10 Round Shotgun Magazine: First Thoughts

As an equipment specialist with over a decade immersed in diverse environments, from dusty workshops to sterile labs and demanding field operations, my standards for gear are high and my scrutiny is unwavering. When it came time to outfit my Mossberg 590M shotgun with additional feeding capacity, the Mossberg Model 590M 12ga 10 Round Shotgun Magazine was the logical, though not unchallenged, choice. My initial hunt for extended magazines for the 590M stemmed from a desire to increase its utility for specific defensive scenarios, where rapid deployment and sustained firing capability are paramount. While I considered aftermarket options, the allure of a factory-designed unit for optimal compatibility and reliability won out, despite some early user chatter about inconsistent quality. My first impression upon unboxing these units was one of solid, purposeful design. The high-impact polymer construction felt robust, and the hardened steel components promised durability. There was an immediate sense of satisfaction in holding what appeared to be a well-engineered component designed specifically for its intended firearm.

Real-World Testing: Putting Mossberg Model 590M 12ga 10 Round Shotgun Magazine to the Test

First Use Experience

My initial testing of the Mossberg Model 590M 12ga 10 Round Shotgun Magazine took place at my local indoor shooting range, a controlled environment ideal for evaluating new feeding mechanisms. I loaded several of these 10-round units, first in the quiet of my garage and then under the audible buzz of the range. The magazines inserted smoothly into the 590M receiver, with a satisfyingly solid click that indicated proper seating. Cycling the action with dummy rounds confirmed they presented rounds reliably to the chamber.

Under live fire conditions, with various 12-gauge loads, these magazines performed exceptionally well. I experienced no failures to feed, no jams, and no issues with the rounds seating or extracting. The double-stack design allowed for a comfortable grip while loading, and the polymer body, while initially a point of concern for some users, proved resilient against minor bumps and scrapes on the range bench.

Extended Use & Reliability

Weeks of range time and simulated drills have only solidified my positive assessment of these magazines. I’ve run them through multiple loading and unloading cycles, simulating the demands of a defensive situation. After filling and emptying each of these Mossberg Model 590M 12ga 10 Round Shotgun Magazine units well over fifty times, they continue to perform without any noticeable degradation in function.

The high-impact polymer body has shown no signs of cracking or significant wear, even after a few accidental drops onto the concrete floor of my workshop. The hardened steel feed lips, a critical component, remain pristine and have consistently guided shells into the action without issue. Cleaning is straightforward; a quick wipe down of the exterior and a brief compressed air blast through the action are usually sufficient. They compare favorably to the single-stack magazines that came with the shotgun, offering a significant capacity advantage without any perceivable compromise in reliability or ease of use.

Breaking Down the Features of Mossberg Model 590M 12ga 10 Round Shotgun Magazine

Specifications

The Mossberg Model 590M 12ga 10 Round Shotgun Magazine is meticulously engineered for its role as a high-capacity feeding device for the Mossberg 590M platform. It boasts a 10-round capacity, a substantial upgrade over standard capacity magazines, which significantly enhances the shotgun’s tactical and defensive potential. The construction features a double-stack high-impact polymer body, a material chosen for its durability, light weight, and resistance to impact.

Integrated within this polymer body is a proprietary self-lubricating polymer tower, designed to ensure smooth and consistent feeding of shells under all conditions. For enhanced durability and feeding reliability, the magazine also incorporates hardened steel components, particularly at crucial points like the feed lips and internal mechanisms. Weighing in at approximately 1.26 lbs, this unit provides a noticeable but manageable increase in the shotgun’s overall weight, a trade-off most users will find acceptable for the increased capacity.

Performance & Functionality

The primary function of any magazine is to reliably feed ammunition into the firearm, and this Mossberg magazine excels in this regard. Its 10-round capacity means fewer reloads during prolonged engagements, a critical factor in defensive scenarios. The double-stack configuration is elegantly designed to present each 12-gauge shell perfectly to the shotgun’s action.

The integration of a self-lubricating polymer tower is a standout feature, contributing to the smooth operation even after repeated cycles. This ensures that shells transition seamlessly from the magazine to the chamber without snagging or binding. Compared to some aftermarket magazines that can be finicky, the factory design minimizes potential points of failure, making it a highly dependable component.

Design & Ergonomics

The design of the Mossberg Model 590M 12ga 10 Round Shotgun Magazine is both functional and robust. The high-impact polymer body is sculpted for a secure grip during magazine changes, even with gloves on or in wet conditions. Its matte black finish is understated and blends well with the firearm’s aesthetics.

Ergonomically, loading the 10 rounds is surprisingly straightforward. The polymer tower allows for easy manipulation of each shell as it’s seated. The hardened steel components, while internal, inspire confidence in the magazine’s structural integrity. There is no real learning curve associated with this unit; it functions as intuitively as any other factory magazine, but with a significantly higher payload.

Durability & Maintenance

In terms of durability, the Mossberg Model 590M 10 Round Magazine is built to last. The high-impact polymer resists cracking and deformation, and the hardened steel elements are resistant to wear. I have personally witnessed the resilience of these materials when subjected to accidental drops on hard surfaces.

Maintenance is refreshingly simple. A quick wipe-down with a cloth is usually all that is needed to keep the exterior clean. For internal cleaning, a blast of compressed air can remove any debris that might accumulate. Unlike some firearms accessories, this magazine doesn’t require specialized tools or intricate disassembly for routine care, making it user-friendly for a wide range of owners.

Accessories and Customization Options

The Mossberg Model 590M 12ga 10 Round Shotgun Magazine does not typically come with additional accessories, as it is a direct replacement or upgrade part. However, its design is proprietary to the Mossberg 590M shotgun, meaning it is not intended for customization with parts from other manufacturers. The primary “accessory” this magazine offers is its 10-round capacity, significantly increasing the shotgun’s operational readiness.

Pros and Cons of Mossberg Model 590M 12ga 10 Round Shotgun Magazine
