ProMag Polymer Smith & Wesson M&P9 9mm 50-Round Pistol Magazine Review

First Impressions of ProMag Polymer Smith & Wesson M&P9 9mm 50-Round Pistol Magazine

The ProMag Polymer Smith & Wesson M&P9 9mm 50-Round Pistol Magazine promises to be a game-changer for anyone seeking increased firepower and reduced reload times with their M&P9. Boasting a 50-round capacity in a polymer body, this magazine aims to deliver reliability and durability without sacrificing weight. As someone who’s spent countless hours at the range and in tactical training scenarios, I was eager to see if this high-capacity magazine could live up to the hype and address some common frustrations with standard-capacity magazines.

I’ve always felt limited by the standard 17-round magazines in my M&P9, especially during drills that require high round counts. The constant need to reload disrupts the flow and can be a disadvantage in dynamic shooting situations. Other high-capacity magazines exist, but many are plagued by reliability issues or excessive weight, so the ProMag piqued my interest because of its polymer construction and the promise of a lighter, more durable solution.

Upon receiving the ProMag Polymer Smith & Wesson M&P9 9mm 50-Round Pistol Magazine, my initial impression was positive. The polymer body felt robust and well-made, and the overall weight seemed manageable despite the significant capacity increase. Compared to some metal high-capacity magazines I’ve used in the past, this one felt noticeably lighter and less bulky. I picked this magazine hoping it would provide a significant advantage in terms of firepower and reload speed, while maintaining the reliability I expect from my M&P9. I was excited and optimistic, hoping this would be a solid addition to my gear.

Real-World Testing: Putting ProMag Polymer Smith & Wesson M&P9 9mm 50-Round Pistol Magazine to the Test

First Use Experience

I first tested the ProMag Polymer Smith & Wesson M&P9 9mm 50-Round Pistol Magazine at my local shooting range, focusing on rapid-fire drills and target transitions. The conditions were relatively mild, with a temperature around 70 degrees Fahrenheit and minimal wind. The initial loading of the magazine was straightforward, although it definitely took more time than loading a standard-capacity magazine due to the sheer number of rounds.

The first few magazines experienced several failures to feed within the first 100 rounds. After some examination, I could see the rounds were not consistently aligning correctly. This was unexpected and concerning.

Extended Use & Reliability

After several weeks of consistent use and about 500 rounds through the ProMag Polymer Smith & Wesson M&P9 9mm 50-Round Pistol Magazine, the reliability issues persisted. Failures to feed were less frequent after the first few loading, but still noticeable. A few rounds of various types helped slightly smooth the initial loading issues.

There are no obvious signs of wear and tear on the polymer body, but the constant loading and unloading began to stress the feeding lips of the magazine. Cleaning the magazine was relatively easy, but disassembling it for a more thorough cleaning proved to be challenging. Comparing my experiences with standard M&P9 magazines, the ProMag‘s reliability falls short, though the increased capacity is a tempting trade off.

Breaking Down the Features of ProMag Polymer Smith & Wesson M&P9 9mm 50-Round Pistol Magazine

Specifications

The ProMag Polymer Smith & Wesson M&P9 9mm 50-Round Pistol Magazine is designed for Smith & Wesson M&P9 pistols chambered in 9mm Luger. The magazine boasts a 50-round capacity, providing significantly more firepower than standard magazines. The magazine body is constructed from a proprietary DuPont Zytel based polymer, aiming for durability and reduced weight.

The follower is injection molded, and the magazine spring is formed from heat treated chrome silicon wire. These specifications are important because they directly influence the magazine’s reliability, durability, and overall performance. A higher capacity allows for fewer reloads, while the polymer construction reduces weight and enhances resistance to impact and environmental factors.

Performance & Functionality

In terms of performance, the ProMag Polymer Smith & Wesson M&P9 9mm 50-Round Pistol Magazine delivers on its promise of increased capacity, but falls short in overall reliability. The magazine allows for extended shooting sessions without the need for frequent reloads, which is a significant advantage in certain scenarios. However, the recurring failures to feed detract from its usability and can be frustrating.

The main strength of this magazine is its high capacity, allowing users to shoot for extended periods without reloading. However, the reliability issues are a significant weakness that needs to be addressed. While the magazine meets the basic expectation of holding and feeding ammunition, it does not consistently perform at a level that inspires confidence.

Design & Ergonomics

The ProMag Polymer Smith & Wesson M&P9 9mm 50-Round Pistol Magazine features a lightweight polymer construction that makes it comfortable to handle, despite its size. The magazine’s design is relatively simple, with a standard profile that fits securely into the M&P9’s magazine well.

The build quality seems solid, with the polymer body feeling durable and well-assembled. However, the learning curve is minimal, as it functions similarly to standard magazines, though the loading process takes longer due to the higher capacity.

Durability & Maintenance

The polymer body of the ProMag Polymer Smith & Wesson M&P9 9mm 50-Round Pistol Magazine suggests it will last a good amount of time with care, but the feeding lip issues are concerning. Cleaning the magazine is relatively straightforward, but disassembling it for a more thorough cleaning can be challenging and requires some patience.

Regular cleaning and proper storage are essential to prolonging the magazine’s lifespan and maintaining its functionality. The magazine’s durability is adequate for recreational use, but its long-term reliability remains a concern based on my experiences.

Accessories and Customization Options

The ProMag Polymer Smith & Wesson M&P9 9mm 50-Round Pistol Magazine does not come with any additional accessories. There are no customization options available directly for the magazine itself. However, it is compatible with any standard M&P9 pistol and does not require any modifications to the firearm. The compatibility with standard M&P9 accessories is a notable advantage, as it allows users to integrate the magazine seamlessly into their existing setups.
