The MOSS 590M MAG 15 ROUND – 12 Gauge Caliber, 15 Rounds, Black, OEM Origin Made a Bold First Impression
The MOSS 590M MAG 15 ROUND – 12 Gauge Caliber, 15 Rounds, Black, OEM Origin promises a significant leap in shotgun capacity, offering a potential game-changer for both tactical and recreational shooters. This magazine, designed specifically for the Mossberg 590M, boasts a double-stack configuration capable of holding 15 rounds of 12-gauge ammunition. As a gear specialist with over a decade in the field, I’ve seen countless accessories come and go, but the allure of a shotgun that could potentially fire fifteen 2.75″ shells without reloading was impossible to ignore.
My primary interest in this magazine stemmed from a desire for increased capacity during practical shotgun competitions and potential home defense scenarios. Reloading can be a costly time sink in competition and a deadly one in a defensive situation. The moment I first held the magazine, the robust construction and aggressive styling immediately spoke volumes.
Unboxing the MOSS 590M MAG 15 ROUND, I immediately noted the weight and the textured grip. It felt substantial, reassuringly solid, and the black oxide finish on the steel components appeared durable. Compared to the standard 5-round magazine that came with my 590M, this behemoth was obviously targeting a different niche.
I considered other high-capacity shotgun options, including drum magazines and modified feeding systems. Ultimately, I opted for the MOSS 590M MAG 15 ROUND due to its promise of maintained balance and superior control compared to single-stack alternatives. My initial impression was one of cautious optimism – excited by the potential, but also aware that high capacity doesn’t always equate to high reliability.
Real-World Testing: Putting MOSS 590M MAG 15 ROUND – 12 Gauge Caliber, 15 Rounds, Black, OEM Origin to the Test
First Use Experience
My first testing ground for the MOSS 590M MAG 15 ROUND was at my local outdoor shooting range. The weather was dry, with a slight breeze – ideal conditions for evaluating any new piece of equipment. Loading the magazine for the first time was surprisingly challenging, especially after about 10 rounds.
It took considerable effort to compress the spring enough to seat the shells, requiring me to brace the magazine against a solid surface as suggested in some user reviews. Once loaded, however, the magazine locked securely into my Mossberg 590M, and the increased weight was noticeable but not unmanageable. The first few shots were smooth and reliable, but I quickly noticed a change in the shotgun’s handling due to the shifted center of gravity.
Extended Use & Reliability
After several range sessions and hundreds of rounds, the MOSS 590M MAG 15 ROUND has proven to be a mixed bag. The magazine body has held up well, with no signs of cracking or deformation, even after being dropped on hard surfaces. Cleaning the magazine is straightforward, thanks to the removable floor plate.
However, I’ve experienced occasional feeding issues, particularly with lighter target loads. Heavier buckshot and slug loads seemed to cycle more reliably, suggesting the spring tension might be optimized for higher-powered ammunition. While the increased capacity is undoubtedly a plus, the inconsistent feeding and difficulty in loading detract from the overall experience, falling short of my initial expectations.

Performance & Functionality
When it functions correctly, the MOSS 590M MAG 15 ROUND delivers a substantial increase in firepower and reduces the frequency of reloads.

The primary strengths are its high capacity and relatively compact size compared to drum magazines.
The magazine’s main weaknesses are the difficulty in loading it to full capacity and its sensitivity to different types of ammunition. It partially meets my expectations, offering increased firepower but falling short in terms of consistent reliability.
Design & Ergonomics
The design of the MOSS 590M MAG 15 ROUND prioritizes capacity and durability. The polymer body is robust and features an easy-grip external molded design.
