First Impressions of ProMag Polymer Browning Hi-Power 9mm 50-Round Pistol Magazine
The ProMag Polymer Browning Hi-Power 9mm 50-Round Pistol Magazine is a bold statement. It promises to dramatically increase the capacity of a classic pistol. I was immediately intrigued by the prospect of a 50-round drum magazine for my Hi-Power.
Years ago, I faced a situation during a training exercise where rapid reloads were crucial, and my standard magazines felt inadequate. This experience sparked my interest in high-capacity options. I hoped this ProMag magazine would offer a solution, providing a significant increase in firepower for range days and potential tactical scenarios.
My first impression upon unboxing was mixed. The polymer felt sturdy but definitely lighter than the steel of the original magazines, and the drum shape seemed a little unwieldy at first glance. Compared to standard capacity magazines, this ProMag product stood out due to its larger size and unique design. I chose it over stick-type extended magazines because I was curious about the potential reliability and higher capacity of a drum.
I was initially cautiously optimistic. The build quality seemed decent for the price, but I reserved full judgment until I could test its performance at the range. The potential for increased firepower excited me, but I also wondered if it would feed reliably.
Real-World Testing: Putting ProMag Polymer Browning Hi-Power 9mm 50-Round Pistol Magazine to the Test
First Use Experience
I tested the ProMag Polymer Browning Hi-Power 9mm 50-Round Pistol Magazine at my local shooting range. The weather was clear and dry, ideal conditions for testing. Loading the magazine was a bit tedious, requiring more time than standard magazines.
During my first use, I experienced several failures to feed within the first 20 rounds. It seemed the magazine spring struggled to keep up with the Hi-Power’s cycling rate. I was disappointed by these initial malfunctions.
Extended Use & Reliability
After several range sessions, I’ve logged hundreds of rounds through this ProMag magazine. While the initial feeding issues lessened after the magazine was “broken in,” they never entirely disappeared. Minor wear marks appeared on the polymer body after repeated use and cleaning.
Cleaning requires a little more effort than standard magazines due to the drum design and larger size. It doesn’t outperform my factory magazines in terms of reliability. My original Browning Hi-Power magazines still provided better, more consistent performance.
Breaking Down the Features of ProMag Polymer Browning Hi-Power 9mm 50-Round Pistol Magazine
Specifications
The ProMag Polymer Browning Hi-Power 9mm 50-Round Pistol Magazine boasts a 50-round capacity. It is chambered in 9mm Luger and designed specifically for the Browning Hi-Power pistol. The magazine body is constructed from a proprietary DuPont Zytel based polymer.
The follower is injection molded, and the magazine spring is formed from heat-treated chrome silicon wire. These materials aim to balance durability with weight savings. The high capacity offered by the magazine theoretically allows for fewer reloads during extended shooting sessions.
Performance & Functionality
When functioning correctly, the ProMag Polymer Browning Hi-Power 9mm 50-Round Pistol Magazine delivers a high volume of fire. However, reliability is its primary weakness. The magazine struggles to consistently feed rounds, leading to stoppages.
It does not fully meet my expectations for reliability. Improvements are needed in spring tension and follower design. Its functionality is significantly hampered by the feeding issues.
Design & Ergonomics
The ProMag Polymer Browning Hi-Power 9mm 50-Round Pistol Magazine’s polymer construction keeps weight relatively low for its capacity. However, the drum shape makes the pistol unwieldy and difficult to holster. The ergonomics are poor compared to standard magazines.
There is a definite learning curve associated with loading and using this magazine. Its bulkiness makes it less comfortable to carry and manipulate.
Durability & Maintenance
The polymer body seems reasonably durable and resistant to impacts. The magazine spring, however, might be a long-term concern, as it seems prone to weakening. Regular cleaning is essential to prevent malfunctions, but the disassembly process is not overly complex.
It is likely to last a decent amount of time with proper care, but I don’t expect it to match the lifespan of steel magazines. Replacement springs may be necessary over time.
Accessories and Customization Options
The ProMag Polymer Browning Hi-Power 9mm 50-Round Pistol Magazine doesn’t offer many customization options beyond its basic design. There are no available grip extensions or base pads. It is primarily designed to function as a standalone high-capacity magazine.
It is not directly compatible with many accessories, as it significantly alters the pistol’s form factor. Holsters designed for standard Hi-Power magazines will not accommodate this drum magazine.
Pros and Cons of ProMag Polymer Browning Hi-Power 9mm 50-Round Pistol Magazine

Who Should Buy ProMag Polymer Browning Hi-Power 9mm 50-Round Pistol Magazine?
This magazine might appeal to range enthusiasts who prioritize high capacity and are willing to tolerate some reliability issues. It is also an option for collectors who want to add a unique accessory to their Browning Hi-Power. Competitive shooters might find it useful in specific scenarios, provided they thoroughly test and address the reliability issues.
This product is not suitable for individuals who rely on their firearm for self-defense or tactical applications. The unreliability makes it a poor choice where consistent performance is critical. Those who prioritize concealed carry should also avoid it due to its bulkiness.
A speed loader designed for pistol magazines would be a must-have accessory to make loading more efficient. Upgrading the magazine spring might improve reliability, but this would require further research and experimentation.
Conclusion on ProMag Polymer Browning Hi-Power 9mm 50-Round Pistol Magazine
The ProMag Polymer Browning Hi-Power 9mm 50-Round Pistol Magazine is a mixed bag. While it delivers on its promise of high capacity, it falls short in terms of reliability. The price is relatively low, but the feeding issues detract from its overall value.
I cannot wholeheartedly recommend it for serious use due to the inconsistent performance. It might be an interesting novelty for range days, but I would advise against relying on it for anything critical. Approach with caution and be prepared to troubleshoot potential feeding problems.
