ProMag FN FNX .45 ACP 15 Round Pistol Magazine Review

First Impressions of ProMag FN FNX .45 ACP 15 Round Pistol Magazine

The ProMag FN FNX .45 ACP 15 Round Pistol Magazine promises to be a reliable and high-capacity alternative to factory magazines for the FNX-45 pistol. Boasting a heat-treated steel construction and a chrome silicone spring, it immediately catches the eye as a potential upgrade for those seeking extra firepower or simply a dependable spare. As someone who relies on my FNX-45 for both range practice and home defense, the allure of a 15-round magazine at a competitive price point is undeniable.

My FNX-45 is my go-to sidearm when hog hunting in dense brush, and the standard magazines sometimes feel lacking. I needed a magazine that could offer higher capacity without sacrificing reliability. I’ve used ProMag magazines in other firearms before, with mixed results, so I approached this purchase with cautious optimism, hoping this model would prove to be a winner.

Upon receiving the ProMag FN FNX .45 ACP 15 Round Pistol Magazine, my first impression was favorable. The blued steel finish looked clean and durable, and the magazine felt solid in hand. It was heavier than the factory magazine, which I attributed to the increased capacity and potentially thicker gauge steel. Compared to a similar magazine from a competitor, like Mec-Gar, the ProMag felt less refined in its finish but potentially more robust.

While I was initially excited about the increased capacity, I also had reservations about potential feeding issues, a common concern with aftermarket magazines. I was hoping to be pleasantly surprised, but prepared for some potential tweaking to ensure flawless function. Time at the range would tell the true story.

Real-World Testing: Putting ProMag FN FNX .45 ACP 15 Round Pistol Magazine to the Test

First Use Experience

I put the ProMag FN FNX .45 ACP 15 Round Pistol Magazine through its paces at my local outdoor shooting range. I primarily used it with standard 230-grain FMJ ammunition, but also ran a few magazines of hollow points for good measure. The weather was clear and dry, around 75 degrees Fahrenheit, ideal conditions for testing.

Initially, the magazine performed surprisingly well. Loading was smooth, though noticeably stiffer than with the factory magazines, especially when nearing full capacity. The magazine locked into the FNX-45 with a positive click, and the first few rounds cycled without issue. However, by the third magazine, I experienced a couple of failures to feed, with the slide failing to fully chamber the round.

Extended Use & Reliability

After several weeks of use, the reliability of the ProMag FN FNX .45 ACP 15 Round Pistol Magazine proved to be inconsistent. While it worked flawlessly for the first few magazines each range session, I consistently encountered feeding issues as the magazine got dirtier or after repeated use. The blued finish showed signs of wear rather quickly, particularly around the feed lips, but there was no significant corrosion.

Cleaning and maintenance were relatively straightforward. Disassembling the magazine for cleaning was simple enough. However, the spring tension was strong, requiring some effort to reassemble. Compared to my experiences with factory magazines, the ProMag required more frequent cleaning to maintain reliable function. The ProMag magazine, unfortunately, didn’t outperform the factory magazines in terms of reliability.

Breaking Down the Features of ProMag FN FNX .45 ACP 15 Round Pistol Magazine

Specifications

The ProMag FN FNX .45 ACP 15 Round Pistol Magazine is designed as a high-capacity replacement magazine for the FN Herstal FNX-45 pistol. It features a .45 ACP caliber and a 15-round capacity, offering a significant increase over the standard 10 or 15-round magazines. The magazine body is constructed from heat-treated steel with a blued finish.

The follower is made from injection-molded polymer, and the magazine spring is formed from chrome silicone wire. These specifications aim to provide durability and consistent feeding. The higher capacity is beneficial for those who want more rounds at their disposal.

Performance & Functionality

In terms of performance, the ProMag FN FNX .45 ACP 15 Round Pistol Magazine is a mixed bag. While it provides the promised 15-round capacity, its reliability is questionable. The feeding issues I experienced, particularly after extended use, are a significant concern.

Its strengths lie in its increased capacity and relatively low price point. Its weaknesses are its inconsistent reliability and the need for frequent cleaning. It partially meets expectations; the capacity is there, but the reliability falls short.

Design & Ergonomics

The ProMag FN FNX .45 ACP 15 Round Pistol Magazine has a straightforward design. The heat-treated steel construction gives it a solid feel, but the blued finish is prone to wear. The increased weight compared to factory magazines is noticeable but not excessive. It is fairly easy to load, although the spring tension becomes quite strong towards the end.

There’s no significant learning curve to using it. It functions like any other pistol magazine.

Durability & Maintenance

The magazine’s durability seems adequate, although the blued finish wears relatively quickly. It is likely to last for a decent amount of time with regular use and proper care. Maintaining the magazine is simple; it can be disassembled and cleaned with standard gun cleaning tools.

Accessories and Customization Options

The ProMag FN FNX .45 ACP 15 Round Pistol Magazine doesn’t come with any accessories. It’s designed to function as a drop-in replacement for the factory magazines. There are no specific customization options for the magazine itself. It should be compatible with standard FNX-45 magazine pouches.

Who Should Buy ProMag FN FNX .45 ACP 15 Round Pistol Magazine?

The ProMag FN FNX .45 ACP 15 Round Pistol Magazine might be suitable for recreational shooters looking for an affordable way to increase their magazine capacity for range use. It could also be a decent option for those who prioritize quantity over ultimate reliability and are willing to perform regular maintenance.

Those who rely on their FNX-45 for self-defense or duty use should probably skip this product. The inconsistent reliability makes it unsuitable for high-stakes situations. A must-have accessory would be a reliable magazine loader, due to the stiff spring.

Conclusion on ProMag FN FNX .45 ACP 15 Round Pistol Magazine

The ProMag FN FNX .45 ACP 15 Round Pistol Magazine offers a tantalizing proposition: increased capacity at an affordable price. However, its inconsistent reliability is a significant drawback. While the magazine might be acceptable for casual range use with diligent maintenance, I cannot recommend it for serious applications where reliability is paramount.

At $33.89, the price is tempting, but ultimately, reliability is more important than saving a few dollars. I would not personally recommend this magazine for anyone who depends on their FNX-45 for self-defense or professional use. Invest in quality factory magazines or other proven aftermarket options for peace of mind.
