ProMag FNHA3 50rd 5.7x28mm Fits FN PS90 Clear Polycarbonate Review

First Thoughts on the ProMag FNHA3 50rd 5.7x28mm Fits FN PS90 Clear Polycarbonate

The FN PS90 is a unique firearm, known for its compact bullpup design and high-capacity magazines. Finding reliable, affordable magazines for it can be a challenge. The ProMag FNHA3 50rd 5.7x28mm Fits FN PS90 Clear Polycarbonate magazine promises both high capacity and a clear body to easily monitor ammunition levels, all at a very attractive price point. This immediately piqued my interest, as factory FN magazines can be quite expensive, and I am always on the lookout for cost-effective training solutions.

I had been searching for a more economical way to feed my PS90 without sacrificing reliability. Factory FN magazines are excellent, but their cost adds up quickly when you’re stocking up. I needed something that could withstand regular range use without breaking the bank. The ProMag offering seemed like a good candidate, but the mixed reviews online gave me pause.

Upon receiving the ProMag FNHA3, my initial impression was mixed. The clear polycarbonate body felt sturdy enough, but not quite as robust as the polymer used in FN factory magazines. The weight was comparable, and the overall dimensions seemed correct. I immediately noticed the four screws holding the top portion of the magazine together, a design choice likely intended to enhance durability.

I considered other aftermarket options, including those from Magpul (though they don’t currently make PS90 mags) and some lesser-known brands. I picked the ProMag primarily due to its availability and relatively low cost. The lifetime warranty also played a role in my decision. The clear body was another selling point, allowing for quick visual confirmation of remaining rounds.

Initially, I was cautiously optimistic. The price was right, but I was also wary of potential reliability issues, given the mixed feedback I had encountered. I was eager to get it to the range and put it through its paces. I hoped it would perform as well as my factory mags, but I was prepared for the possibility of malfunctions.

Real-World Testing: Putting ProMag FNHA3 50rd 5.7x28mm Fits FN PS90 Clear Polycarbonate to the Test

First Use Experience

My first range session with the ProMag FNHA3 was held at my local outdoor shooting range. The weather was mild and dry, ideal for testing. I loaded the magazine with 50 rounds of Federal American Eagle 5.7x28mm ammunition. Loading was a bit stiff compared to my FN magazines, requiring a little extra effort.

The first few rounds cycled without issue, but around round 15, I experienced a failure to feed. The round nosedived into the feed ramp. I cleared the malfunction and continued shooting. The issue reappeared intermittently throughout the first magazine, occurring approximately every 10-15 rounds. This was disappointing.

The clear body, however, did prove useful. I could quickly see how many rounds I had left, even with the stoppages. I tried adjusting my grip and the way I was holding the PS90, but it didn’t seem to affect the malfunctions.

Extended Use & Reliability

Over the next few months, I continued to test the ProMag FNHA3 during regular range visits. I put approximately 500 rounds through it. The frequency of failures to feed decreased slightly with use, but they never completely disappeared. The magazine became slightly easier to load after repeated use.

Visually, the magazine held up well. There were no cracks or significant wear marks on the polycarbonate body. I noticed some minor scuffing, but nothing that affected its functionality. Cleaning was simple; I disassembled the magazine and wiped down the internal components.

Compared to my experience with factory FN magazines, the ProMag fell short. The FN magazines have been flawless, with zero malfunctions after thousands of rounds. The ProMag’s intermittent failures to feed make it unsuitable for defensive use, in my opinion. It’s fine for range practice, but not something I would trust my life to.

• Caliber: 5.7x28mm – This is the specific ammunition this magazine is designed to feed.

• Compatibility: FN PS90/P90 – Designed to fit and function in these specific firearms.

Performance & Functionality

The ProMag FNHA3 performs adequately for range use, but reliability is inconsistent.

While the high capacity is appealing, the intermittent failures to feed detract from its overall functionality. It is definitely not as reliable as the factory FN mags.

The clear body is a great feature for quickly assessing remaining rounds. The magazine loads relatively easily after some break-in, but initially, it can be stiff.

Design & Ergonomics

The ProMag FNHA3 features a clear polycarbonate body, allowing for easy visual confirmation of remaining rounds. The design closely resembles the factory FN magazine, ensuring a proper fit in the PS90.

The four screws at the top of the magazine suggest an attempt to improve durability. The magazine is relatively lightweight, similar to the factory mags. There isn’t a significant learning curve to using the magazine.

Durability & Maintenance

The polycarbonate body seems durable enough for regular range use, but it is unlikely as rugged as the polymer used in factory magazines.

Disassembly for cleaning is relatively simple, requiring only a punch or similar tool to depress the baseplate retainer. Regular cleaning is recommended to maintain optimal performance. The screws on top of the magazine are supposed to offer extra strength to a common failure point with glued magazines.

Accessories and Customization Options

The ProMag FNHA3 doesn’t offer significant customization options.

It is compatible with most standard PS90 magazine loaders. There are no aftermarket baseplates or other accessories specifically designed for this magazine that I am aware of.
