First Impressions of ProMag Steel FN 509 9mm 20-Round Pistol Magazine
The ProMag Steel FN 509 9mm 20-Round Pistol Magazine promises to be a high-capacity, durable alternative to the factory magazines for the FN 509. With its heat-treated steel construction and chrome silicon spring, it aims to provide reliable feeding and long-lasting performance, addressing a common desire for increased capacity in a popular pistol platform. As someone who’s relied on firearms in demanding environments for over a decade, I’m always on the lookout for magazines that can withstand rigorous use and offer a competitive edge.
I’ve often found myself wanting more rounds in my FN 509, especially during training drills. Factory magazines can be expensive and sometimes difficult to find in stock. This is what led me to seek out reliable aftermarket options that would increase my capacity.
Upon receiving the ProMag, my initial impression was positive, noting the robust feel of the steel body. The weight felt reassuring, suggesting a solid build, unlike some flimsy aftermarket magazines I’ve encountered. The black oxide finish appeared evenly applied, providing a decent level of corrosion resistance.
Compared to the factory FN 509 17-round magazine and a couple of other aftermarket options I’ve tried (a KCI magazine and a Strike Industries EMP), the ProMag seemed to have a sturdier build than the KCI, though not quite as refined as the factory mag. I picked the ProMag over others because of the promised high capacity and the reputation of ProMag for producing affordable, if sometimes inconsistent, magazines. I was cautiously optimistic.
Initially, I was cautiously optimistic, hoping it would live up to its claims and provide a reliable boost in firepower. However, I also knew that ProMag had a mixed reputation, so I was prepared to thoroughly test its performance before trusting it completely.
Real-World Testing: Putting ProMag Steel FN 509 9mm 20-Round Pistol Magazine to the Test
First Use Experience
I first tested the ProMag Steel FN 509 9mm 20-Round Pistol Magazine at my local shooting range, focusing on various drills involving rapid fire and magazine changes. The range provided a controlled environment to assess its feeding and reliability. I tested with various ammo brands to see if there were any issues with specific types.
The magazine performed reasonably well in dry conditions, but I did notice a couple of failures to feed with cheaper, bulk-packed ammunition. I was able to resolve those malfunctions quickly. It did require a bit of extra force to seat when fully loaded, especially with the slide forward.
The initial use was generally positive, but the few hiccups raised a slight concern that would need to be addressed with further testing. I wasn’t immediately impressed.
Extended Use & Reliability
After several weeks of consistent use, I observed the ProMag showing some minor cosmetic wear on the finish, particularly around the feed lips. This was a bit disappointing, but didn’t seem to affect functionality yet. The springs seem to be holding up and continue to give positive pressure.
There were no significant signs of damage beyond surface-level wear. Cleaning was straightforward. I disassembled it after each range session, wiped down the internals, and applied a light coat of lubricant.
Compared to my experiences with the factory FN magazines, the ProMag doesn’t quite reach the same level of reliability or smoothness. However, considering the price point and increased capacity, it offers an acceptable trade-off for range use and training.
Breaking Down the Features of ProMag Steel FN 509 9mm 20-Round Pistol Magazine
Specifications
The ProMag Steel FN 509 9mm 20-Round Pistol Magazine is designed specifically for the FN 509 pistol, chambered in 9mm Luger. It boasts a 20-round capacity, providing a significant increase over the standard 17-round magazines. The magazine body is constructed from heat-treated steel, finished with a black oxide coating for corrosion resistance.
The high carbon, heat-treated steel body is TIG-welded, a plus for strength and durability. The heat treatment helps to maintain its shape and integrity under the stresses of repeated loading and firing.
The magazine spring is formed from heat-treated chrome silicone wire. This material is known for its resistance to fatigue, ensuring consistent feeding pressure over time.
The follower is injection molded from a durable polymer. This helps ensure smooth feeding and reduces friction within the magazine body.
These specifications are critical because they directly impact the magazine’s ability to consistently feed ammunition, withstand wear and tear, and resist corrosion. A well-built magazine is essential for reliable firearm performance.
Performance & Functionality
The ProMag Steel FN 509 9mm 20-Round Pistol Magazine generally performs adequately, offering a higher capacity while maintaining acceptable reliability. While it doesn’t match the flawless performance of the factory magazines, it’s usable. The increased capacity is valuable for scenarios where additional rounds could be an advantage.
The magazine’s primary weakness is its occasional failure to feed, particularly with lower-quality ammunition. However, its strengths include its high capacity and robust steel construction.
It generally meets expectations for an aftermarket magazine in this price range, but falls short of the gold standard set by FN factory magazines.
Design & Ergonomics
The ProMag Steel FN 509 9mm 20-Round Pistol Magazine features a simple, functional design with a matte black finish. The steel body gives it a substantial feel, inspiring confidence in its durability.
The magazine is relatively user-friendly, but as mentioned earlier, it can be a bit difficult to seat fully when loaded to capacity. The learning curve is minimal.
Durability & Maintenance
The heat-treated steel construction suggests that the ProMag should have a reasonable lifespan, although the finish may show wear over time. With proper care and maintenance, it should provide years of service.
Disassembly for cleaning is easy, and no special tools are required. Regular cleaning and lubrication will help to maintain its performance and prolong its life.
Accessories and Customization Options
The ProMag Steel FN 509 9mm 20-Round Pistol Magazine doesn’t come with any additional accessories. It’s a standalone product designed to directly replace or supplement existing FN 509 magazines.
There are no specific customization options for the ProMag itself. However, because it is designed to work with the FN 509 pistol, it is compatible with any accessories designed for that firearm, such as aftermarket baseplates or magazine pouches.
