The ProMag FNH-A2 FN FiveseveN USG Magazine 30RD 5.7x28mm Black Polymer – 5.7mm x 28mm Caliber, 30 Rounds, Aftermarket Origin, Five-Seven Model Made a Bold First Impression
The FN FiveseveN is a unique pistol, known for its high-velocity, low-recoil 5.7x28mm cartridge. Standard magazines offer decent capacity, but sometimes you just want more rounds downrange without a reload. Enter the ProMag FNH-A2 FN FiveseveN USG Magazine 30RD 5.7x28mm Black Polymer – 5.7mm x 28mm Caliber, 30 Rounds, Aftermarket Origin, Five-Seven Model, promising to nearly double the standard magazine’s capacity.
My interest in this magazine stemmed from a desire for extended range sessions and a potential edge in dynamic shooting scenarios. Reloading drills are crucial, but having 30 rounds on tap offers a distinct advantage. This is especially true when practicing transitions between multiple targets or running complex drills.
Upon receiving the ProMag magazine, my initial impression was mixed. The polymer felt sturdy enough, though not quite as refined as the factory FN magazines. The extended length was noticeable, but the included grip sleeve was a welcome addition.
I considered other aftermarket magazines, but the ProMag seemed to strike a balance between capacity and price. Factory FN magazines are expensive, and some other extended magazines had questionable reviews. The ProMag offered a more affordable option with a decent reputation, making it worth a try.
My first impression was cautiously optimistic. The build quality seemed adequate, but the real test would be its performance at the range. I was eager to see if it lived up to its promise of reliable feeding and increased firepower.

First Use Experience
My first range session with the ProMag was on a sunny afternoon at my local outdoor range. I loaded it with 28 rounds, heeding the advice of other users who reported potential issues with a fully loaded 30-round capacity. I wanted to minimize any chances of a malfunction during this initial test.
The magazine seated firmly in my FiveseveN USG. I ran several drills, focusing on speed and accuracy. During rapid-fire sequences, the ProMag fed flawlessly, keeping up with my pace without any hiccups.
There was a slight stickiness when dropping the magazine, but nothing major. I chalked it up to the newness of the polymer and the tight fit of the included grip sleeve. Overall, the first session was surprisingly smooth.
Extended Use & Reliability
After several months of consistent use, the ProMag has proven to be a reliable addition to my range gear. I’ve put hundreds of rounds through it, experiencing only a couple of minor feeding issues, typically when the magazine was loaded to its full 30-round capacity. Sticking to 28 rounds seems to be the sweet spot.
The polymer has held up well, showing only minor signs of wear around the feed lips and the baseplate. Cleaning is simple: a quick wipe down with a cloth and a brush to remove any debris. It disassembles easily for more thorough cleaning if needed.
Compared to my experience with some other aftermarket magazines, the ProMag has been a clear winner. It offers a significant capacity increase without sacrificing reliability, making it a worthwhile investment. The few minor issues are easily managed with proper loading and maintenance.
