The Shield Arms S15 Magazine Black 9mm 15-Rounds for Glock 43X/48 – 9mm Caliber, 15 Rounds, Black Made a Bold First Impression
The Shield Arms S15 Magazine Black 9mm 15-Rounds for Glock 43X/48 – 9mm Caliber, 15 Rounds, Black promises to drastically improve the capacity of the popular Glock 43X and 48 pistols. With a bump from the factory standard of 10 rounds to a more substantial 15 rounds, this magazine from Shield Arms aimed to address a common complaint among owners of these slimline Glocks – limited firepower.
I often carry my Glock 43X, but the 10-round magazine capacity always felt like a compromise, especially when I’m out hiking in areas where encounters with wildlife or other threats are a real possibility. I needed a solution that wouldn’t significantly increase the gun’s profile, but would provide a greater sense of security.
Upon receiving the Shield Arms S15 Magazine Black 9mm 15-Rounds for Glock 43X/48 – 9mm Caliber, 15 Rounds, Black, I was immediately impressed with its solid construction. The magazine felt sturdy and well-made, with a smooth black finish and a reassuring weight that hinted at the quality of materials used.
I considered options from other aftermarket manufacturers, as well as carrying a spare factory magazine. However, the S15 offered a compelling combination of increased capacity within the same form factor as the original magazine.
My first impression was one of cautious optimism. I was excited about the potential for increased capacity, but also slightly apprehensive about reliability, as aftermarket magazines can sometimes be problematic.
Real-World Testing: Putting Shield Arms S15 Magazine Black 9mm 15-Rounds for Glock 43X/48 – 9mm Caliber, 15 Rounds, Black to the Test
First Use Experience
I first tested the Shield Arms S15 Magazine Black 9mm 15-Rounds for Glock 43X/48 – 9mm Caliber, 15 Rounds, Black at my local shooting range. I wanted a controlled environment to assess its performance before relying on it for everyday carry.
The S15 magazines were tested in both my Glock 43X and Glock 48 under typical range conditions: dry, moderate temperature, and using a variety of 9mm ammunition brands and grain weights. Installing the required Shield Arms steel magazine catch was straightforward, following the detailed instructions provided by Shield Arms and available online.
Initially, the magazine loaded smoothly, and the first few rounds chambered and fired without issue. However, I experienced a few failures to feed within the first 50 rounds, which required me to manually cycle the slide.
Extended Use & Reliability
After the initial range session, I dedicated myself to thoroughly testing the Shield Arms S15 Magazine Black 9mm 15-Rounds for Glock 43X/48 – 9mm Caliber, 15 Rounds, Black over several weeks. I put approximately 500 rounds through each of the three magazines I purchased, meticulously documenting any malfunctions.
Over time, the reliability improved significantly. After the initial “break-in” period, the magazines ran much more smoothly, with only an occasional failure to feed occurring every 100-200 rounds.
Durability seems to be a strong point; after several weeks of use and repeated loading/unloading, there are minimal signs of wear and tear. Cleaning the magazines is relatively easy, requiring only a simple disassembly and wipe-down with a cloth and solvent.
Compared to my previous experience with aftermarket Glock magazines, which were often plagued with persistent reliability issues, the S15 offered a noticeable improvement, especially after the break-in period. While not flawless, their performance was acceptable for range use and potentially for concealed carry after extended testing and confidence building.
