First Impressions of ProMag Polymer Glock 17/19/26 9mm 20-Round Pistol Magazine
The ProMag Polymer Glock 17/19/26 9mm 20-Round Pistol Magazine promises increased capacity and compatibility with a range of popular Glock models. ProMag is a well-known name in the aftermarket magazine world, often offering more affordable alternatives to factory magazines. This particular magazine seeks to bridge the gap between standard capacity and high capacity without the unwieldiness of some extended magazines.
My interest in the ProMag magazine stemmed from reliability issues I was experiencing with other aftermarket Glock magazines in my 9mm Pistol Caliber Carbine (PCC). The factory Glock magazines were perfect, but the cost adds up quickly, especially when needing multiple magazines for competition. I needed reliable magazines that wouldn’t break the bank.
Upon receiving the magazine, I immediately noticed the lightweight feel of the DuPont Zytel based polymer construction. It didn’t feel cheap, but it definitely felt different than the steel-lined factory Glock magazines. The texture was smooth but provided enough grip to easily manipulate during magazine changes.
Compared to the Magpul PMAG GL9 and Amend2 Glock magazines, the ProMag initially felt more robust than the Amend2 but less refined than the Magpul. The Magpul offered a slightly better grip texture, while the Amend2 felt a bit flimsy. I was cautiously optimistic; the price was right, and the build seemed decent, but range testing would be the ultimate test.
My first impression was cautiously optimistic. If it could feed reliably in my PCC, it would be a winner.
Real-World Testing: Putting ProMag Polymer Glock 17/19/26 9mm 20-Round Pistol Magazine to the Test
First Use Experience
The initial range trip involved testing the ProMag Polymer Glock 17/19/26 9mm 20-Round Pistol Magazine in my 9mm PCC and my Glock 19. I ran about 200 rounds through the ProMag in each firearm, alternating between various bullet weights and brands of 9mm ammunition. The weather was clear and dry, with temperatures around 70 degrees Fahrenheit.
In both the PCC and the Glock 19, the ProMag performed flawlessly during that initial session. I experienced no failures to feed, failures to eject, or any other malfunctions. Magazine insertion and ejection were smooth, and the magazine locked the slide back reliably after the last round.
Extended Use & Reliability
After several months and over 1000 rounds through the ProMag, I can confidently say it has become one of my go-to magazines for my 9mm PCC. It has proven to be remarkably reliable, even with cheaper, bulk-packaged ammunition that sometimes causes issues with other magazines. There are no signs of cracking or deformation.
The polymer body has held up well, showing only minor scuff marks from repeated use. Cleaning is straightforward; I simply wipe it down with a cloth and occasionally use a brush to remove any stubborn carbon buildup. The magazine spring tension remains strong, ensuring consistent feeding.
Compared to my previous experiences with aftermarket Glock magazines, the ProMag has significantly outperformed the Amend2 magazines, which experienced frequent failures to feed in my PCC. While the Magpul magazines are generally reliable, the ProMag has been equally reliable in my specific PCC build and at a slightly lower price point. This makes the ProMag the most cost-effective, reliable option for me.
Breaking Down the Features of ProMag Polymer Glock 17/19/26 9mm 20-Round Pistol Magazine
Specifications
The ProMag Polymer Glock 17/19/26 9mm 20-Round Pistol Magazine is designed to be compatible with Glock models 17, 19, and 26, all chambered in 9mm Luger. Its most significant feature is its 20-round capacity, offering a substantial increase over the standard capacity magazines for the Glock 19 and 26. The magazine body is constructed from a DuPont Zytel based polymer, known for its strength and impact resistance.
The follower is injection molded, ensuring smooth and consistent feeding. The magazine spring is formed from heat-treated chrome silicon wire, which is designed to maintain its tension and prevent premature degradation over time. These specifications are crucial for reliable feeding and overall magazine longevity.
Performance & Functionality
The ProMag Polymer Glock 17/19/26 9mm 20-Round Pistol Magazine performs its primary job – feeding ammunition – very well. In my experience, it has been highly reliable in both my Glock 19 and my 9mm PCC. I have not experienced any significant issues with feeding, ejection, or slide lock.
Its main strength is its increased capacity without a significant increase in size or weight. The polymer construction makes it lightweight and resistant to corrosion. However, the polymer construction may not be as durable as a steel-lined magazine in extreme conditions.
The ProMag magazine meets and, in some cases, exceeds my expectations. Its reliability in my picky PCC has been a pleasant surprise.
Design & Ergonomics
The design of the ProMag Polymer Glock 17/19/26 9mm 20-Round Pistol Magazine is functional and straightforward. The polymer body is lightweight and provides a decent grip surface. The magazine is easy to load and insert into the magazine well.
The slightly extended length, due to the increased capacity, does not significantly impact concealability or handling. There is a slight learning curve involved in ensuring the magazine is fully seated, especially when fully loaded, but this is common with extended capacity magazines.
Durability & Maintenance
Based on my experience, the ProMag Polymer Glock 17/19/26 9mm 20-Round Pistol Magazine appears to be durable enough for regular range use and competition. The polymer construction is resistant to cracking and deformation under normal conditions. However, I would not expect it to withstand the same level of abuse as a steel-lined magazine.
Maintenance is simple; I regularly clean the magazine with a cloth and a brush. Disassembly for more thorough cleaning is possible but not usually necessary.
Accessories and Customization Options
The ProMag Polymer Glock 17/19/26 9mm 20-Round Pistol Magazine doesn’t come with any specific accessories. It is compatible with standard Glock magazine pouches and magazine loaders. There are no specific customization options for the magazine itself, although it can be used with aftermarket base plates designed for Glock magazines.
