Cross Armory CRG+5MEG17BK Magazine Extension Fits Glock 17 Gen 1-5 5rd Black Aluminum
A Cross Armory magazine extension for Glock 17 gives your carry or duty pistol a practical capacity boost without the bulk of a full-size alternative. This 5-round aluminum extension fits Glock 17 Gen 1 through Gen 5 models, making it a solid choice whether you're running a vintage Gen 1 or the latest Gen 5 platform. The black aluminum construction keeps weight minimal while adding reliable rounds to your magazine, and the design integrates seamlessly with standard Glock 17 mags to maintain your gun's handling characteristics.
Magazine extensions appeal to shooters who want to squeeze extra capacity into a carry gun without sacrificing concealability or switching to a larger frame. The 5-round addition is a moderate step—enough to matter in a defensive scenario or at the range, without printing under a cover garment or dramatically changing how your pistol sits in a holster. If you're training hard or carrying regularly, those extra rounds provide a meaningful reserve without the trade-offs of going full-size.
Cross Armory's aluminum construction is built to handle repeated loading cycles and real-world carry. Compatibility across all Gen 1–5 Glock 17 variants means this extension will work with your current gun and any Glock 17 you might pick up in the future, making it a practical long-term investment for serious Glock users.
