ProMag AR-15 9mm Colt/SMG 25-Round Magazine Review

Is the ProMag Steel AR-15 9mm Colt/SMG Type 25-Round Rifle Magazine Worth It? Let’s Find Out

In the AR-15 platform, reliable magazines are the lifeblood of the system. And when you start venturing into different calibers like 9mm, that reliability becomes even more crucial. The ProMag Steel AR-15 9mm Colt/SMG Type 25-Round Rifle Magazine promises to deliver that reliability with its steel construction and high capacity. It aims to bridge the gap between affordability and performance in a market flooded with polymer options.

I’ve been searching for a more robust magazine option for my 9mm AR build. The polymer magazines I’ve been using have shown signs of wear, especially around the feed lips. The promise of a steel magazine that can withstand more abuse definitely piqued my interest.

Upon receiving the ProMag Steel AR-15 9mm Colt/SMG Type 25-Round Rifle Magazine, the first thing I noticed was the weight. It’s definitely heavier than the polymer magazines I’m used to. The steel body felt solid, and the black oxide finish gave it a tactical appearance.

Compared to a Glock magazine adapter with standard Glock magazines, or even a dedicated polymer 9mm AR magazine from another brand, the ProMag felt like a different beast altogether. I chose this magazine hoping for increased durability and consistent feeding in my AR-9. The Glock magazines worked, but always felt “makeshift”.

My first impression was cautiously optimistic. The magazine felt well-built, but I knew the real test would be at the range. I was excited to see if the steel construction translated to improved reliability.

Real-World Testing: Putting ProMag Steel AR-15 9mm Colt/SMG Type 25-Round Rifle Magazine to the Test

First Use Experience

I tested the ProMag Steel AR-15 9mm Colt/SMG Type 25-Round Rifle Magazine at my local outdoor range. I ran it through several drills with various types of 9mm ammunition. This included 115gr FMJ, 124gr FMJ, and some 147gr JHP rounds.

The weather was dry and sunny, around 75 degrees Fahrenheit. Loading the magazine was straightforward, although the steel construction made it a little stiffer than polymer magazines. I experienced one failure to feed within the first 50 rounds.

After the initial hiccup, the magazine ran smoothly. I did not have to make any adjustments to get used to it. The failure to feed was the only issue.

Extended Use & Reliability

After several range trips spanning a couple of months, the ProMag Steel AR-15 9mm Colt/SMG Type 25-Round Rifle Magazine has held up surprisingly well. There are some minor scratches on the finish from inserting and removing it from the magazine well. It’s to be expected with a steel magazine.

Durability-wise, the feed lips have remained intact, and the magazine body shows no signs of bending or warping. The magazine has remained durable through extensive use and drills. The durability is what sets this magazine apart from polymer ones.

Cleaning the magazine is simple. I disassemble it, wipe down the components, and lightly lubricate the spring. It’s a bit more involved than cleaning a Glock magazine. Compared to the polymer magazines I was using previously, the ProMag has definitely outperformed them in terms of durability and overall reliability.

Accuracy is not directly affected by the magazine, but consistent feeding contributes to maintaining a steady shooting rhythm.
