PROMAG Fits GLOCK 17/19/26 9MM (25) RD BLACK POLYMER MAGAZINE

The PROMAG Fits Glock 17/19/26 9mm 25-round Black Polymer Magazine delivers reliable, cost-effective ammunition capacity for operators who demand dependable feeding without premium pricing. This aftermarket Glock magazine is purpose-built for high-round-count training, duty use, and range applications where standard-capacity magazines require frequent reloads.

Construction centers on a proprietary DuPont Zytel-based polymer body engineered for impact resistance and dimensional stability across temperature extremes. The magazine features a full-length steel internal insert—stamped and welded using factory-grade methodology—that prevents flex and binding under sustained fire. The injection-molded follower ensures consistent round stacking, while the heat-treated chrome silicon wire spring maintains tension throughout the magazine's service life. Made in the USA, this magazine delivers proven reliability in patrol carbines, competition, and defensive handgun training where extended magazines reduce transition time between magazines.

This magazine is compatible with Glock 17, 19, and 26 9mm pistols, making it a practical choice for agencies and shooters operating multiple Glock platforms. The 25-round capacity bridges the gap between standard 15-17 round factory magazines and larger extended-capacity alternatives, offering a balance between concealment and firepower for duty, training, and sport shooting. Operators running high-volume range sessions or service rifle carbines benefit from the reduced reload frequency and uniform magazine performance across identical units.
