The ProMag Polymer Black Magazine for Glock 22, 23, 27 in .40 S&W fills a real gap in the aftermarket mag world. While most magazine manufacturers chase 9mm volume, .40 shooters often get left with factory options alone — until now. If you run a Glock 22, 23, or 27 and want reliable, high-capacity alternatives for duty, sport shooting, or personal defense, these polymer mags deliver the expanded flexibility serious .40 users need.
Built from DuPont Zytel polymer, the same material trusted in demanding applications across the industry, these magazines are engineered to handle repeated loading, shooting, and storage without degradation. The feed lips and body geometry are spec'd for the .40 S&W cartridge and designed to work seamlessly with your Glock platform. A heat-treated chrome-silicon wire spring provides consistent feeding pressure across the full capacity range — critical for reliability when you need it most. All construction is domestic; these mags are made in the USA with an all-black finish that matches your pistol's aesthetics.
Whether you're building a backup mag supply, want to run higher capacity during training or competition, or simply prefer to have options beyond factory mags, ProMag's offering gives .40 shooters a proven alternative backed by a durable polymer design and American manufacturing.
