MOSS 590M MAG 10 ROUND – 12 Gauge Caliber, 10 Rounds, Black, OEM Origin Review

The MOSS 590M MAG 10 ROUND – 12 Gauge Caliber, 10 Rounds, Black, OEM Origin Made a Bold First Impression

The MOSS 590M MAG 10 ROUND – 12 Gauge Caliber, 10 Rounds, Black, OEM Origin represents a significant step forward in shotgun magazine design, offering a double-stack, higher-capacity alternative to traditional single-stack options. This magazine, designed specifically for the Mossberg 590M platform, promises improved balance, faster reloads, and increased firepower in a compact package. It’s a departure from the norm, and as someone who’s spent over a decade handling shotguns in various tactical and sporting scenarios, I was eager to see if it lived up to the hype.

My interest in the MOSS 590M MAG 10 ROUND stemmed from a desire to enhance the capabilities of my Mossberg 590. I’ve always appreciated the reliability of the 590 platform but felt limited by the standard capacity. The promise of a 10-round magazine that wouldn’t significantly extend beyond the receiver was incredibly appealing.

Upon receiving the MOSS 590M MAG 10 ROUND, my first impression was that this thing is built like a tank. The OEM origin assures quality, and the weight reflects the robust materials used. The hardened steel feed lips and over-molded steel shell ramps inspire confidence in its ability to reliably cycle rounds.

Compared to standard capacity Mossberg 500/590 magazines, the MOSS 590M MAG 10 ROUND is noticeably wider but not significantly longer. I also considered aftermarket extended magazine tubes, but they alter the balance of the shotgun and can be cumbersome. This magazine offered a more integrated and balanced solution.

My initial reaction was excitement tempered with a bit of skepticism. Could a double-stack 12-gauge magazine truly function reliably in a shotgun known for its rugged simplicity? The MOSS 590M MAG 10 ROUND looked and felt the part, but the real test would be on the range.

Real-World Testing: Putting MOSS 590M MAG 10 ROUND – 12 Gauge Caliber, 10 Rounds, Black, OEM Origin to the Test

First Use Experience

My first range trip with the MOSS 590M MAG 10 ROUND was at my local outdoor shooting range. I wanted to push it through its paces under controlled conditions. The weather was clear and dry, providing optimal testing conditions.

The initial loading process was smooth, although the double-stack design requires slightly more effort to load than a single-stack. Once inserted into the 590M receiver, the magazine locked in place securely with an audible click. Cycling the action felt smooth, and the first few rounds ejected without issue.

After about 20 rounds, I experienced a single failure to feed, which I attributed to not seating the magazine firmly enough on one reload. Correcting my technique, the magazine performed flawlessly for the next 80 rounds.

Extended Use & Reliability

After several weeks and hundreds of rounds, the MOSS 590M MAG 10 ROUND has proven to be remarkably reliable. I’ve used it in various training scenarios, including rapid-fire drills and tactical exercises. The magazine has consistently performed well, with only occasional user-induced errors.

Durability has also been impressive. Despite repeated loading, unloading, and dropping the magazine onto hard surfaces, there are no visible signs of damage or wear. The black oxide finish on the steel components has held up well.

Cleaning and maintenance are straightforward. The removable floor plate allows for easy disassembly and cleaning of the internal components. A quick wipe-down with a CLP after each range session keeps the magazine in top condition.

Compared to my previous experiences with standard-capacity shotgun magazines, the MOSS 590M MAG 10 ROUND offers a significant advantage in firepower and reload speed. It gives me a greater sense of confidence in a defensive situation and has proven to be a valuable addition to my 590 platform.
