ETS MAG FOR GLK 17/19 9MM 40RD CSMK – 9mm Caliber, Aftermarket Origin Review

First Thoughts on the ETS MAG FOR GLK 17/19 9MM 40RD CSMK – 9mm Caliber, Aftermarket Origin

The ETS MAG FOR GLK 17/19 9MM 40RD CSMK – 9mm Caliber, Aftermarket Origin promises increased capacity and enhanced reliability for Glock users, but does it deliver? As someone who’s spent years relying on Glock platforms in various tactical and competitive environments, I’m always searching for ways to improve performance. The promise of 40 rounds in a magazine compatible with both the Glock 17 and 19 immediately piqued my interest.

My agency requires regular range qualifications, and frankly, reloading drills during those scenarios can be a pain, slowing down overall performance. This magazine’s higher capacity seemed like a good solution, potentially reducing the number of reloads needed during timed drills and offering a tactical advantage. Unboxing the ETS MAG FOR GLK 17/19 9MM 40RD CSMK – 9mm Caliber, Aftermarket Origin, my initial impression was mixed.

The Carbon Smoke finish looked sleek, but the polymer felt slightly less robust than the factory Glock magazines I’m accustomed to. I have used Magpul Glock magazines in the past, and compared to those, the ETS magazine felt a bit lighter, which could be a plus or minus depending on how it affects durability. Initial thoughts: cautiously optimistic, but ready to put it through its paces.

Real-World Testing: Putting ETS MAG FOR GLK 17/19 9MM 40RD CSMK – 9mm Caliber, Aftermarket Origin to the Test

First Use Experience

My first range session with the ETS MAG FOR GLK 17/19 9MM 40RD CSMK – 9mm Caliber, Aftermarket Origin was at an outdoor range under typical sunny conditions. I ran it through my Glock 17 and Glock 19, alternating between various 9mm loads, including standard 115-grain FMJ, 124-grain +P hollow points, and even some heavier 147-grain subsonic rounds. The magazine loaded easily enough, although fully loading all 40 rounds required a bit of effort, especially towards the end.

Both the Glock 17 and 19 accepted the magazine without issue, and the initial few magazines fired flawlessly. However, after about 100 rounds, I started experiencing occasional failures to feed, particularly with the hollow point rounds. The magazine also seemed to have some issues in rapid firing strings from my Glock 19.

Extended Use & Reliability

After several weeks of use and approximately 500 rounds through the ETS MAG FOR GLK 17/19 9MM 40RD CSMK – 9mm Caliber, Aftermarket Origin, I’ve developed a more nuanced opinion. The failures to feed persisted, especially when the magazine was fully loaded or near capacity. Durability-wise, the magazine body seems reasonably robust, showing only minor scuff marks from insertion and removal.

Cleaning is straightforward, though disassembling the magazine requires a small punch or similar tool. Comparing it to my experiences with factory Glock magazines, the ETS magazine falls short in reliability. Glock magazines are famous for their dependability and the ETS mag clearly is not up to that level of quality.
