ProMag GLK15 StandardBlack DuPont Zytel Polymer Detachable 10rd for 40 S&W Glock 23/22/27

The ProMag GLK15 is a 10-round magazine purpose-built for Glock .40 S&W platforms—specifically the Glock 23, 22, and 27. If you shoot one of these popular duty or defensive pistols and need reliable, domestically-made backup magazines or spares for the range, this is a straightforward, no-frills option. ProMag has been supplying shooters with made-in-the-USA magazines for years, and the GLK15 carries that same manufacturing discipline: precision assembly, tested springs, and consistent performance without the price tag of premium alternatives.

Built from durable DuPont Zytel polymer, this magazine is lightweight and corrosion-resistant—a practical choice if you're rotating between the range, duty carry, or storage. The black polymer body integrates with the aesthetic of most Glock setups. The real backbone of any magazine is its spring, and ProMag uses heat-treated chrome silicon wire—the kind you'll find in quality factory magazines—wound and seated to exacting standards. Every step of assembly is checked twice before it ships, a discipline that matters when reliability is non-negotiable.

ProMag backs every GLK15 with a lifetime warranty against manufacturer defects, so if something is wrong out of the box, you're covered. Whether you're stocking spares for a 9mm duty pistol and need a dedicated .40 mag, rounding out a rotation, or simply looking to keep a few quality backups on hand without the premium cost, the GLK15 delivers the essentials: proper fitment, proven materials, and domestic manufacturing. Load it up and train with it—it's built to work.
