ProMag Glock 17 19 26 18 Round 9MM Magazine Black GLK A9B UPC 708279013607
Product Description
The ProMag Glock 17/19/26 18-Round 9mm Polymer Magazine (GLK-A9B) is an economical, high-capacity replacement magazine designed for full-size, compact, and subcompact 9mm Glock handguns. Offering an extra round over standard flush-fit 17-round Glock 17 magazines, this 18-round body provides extended capacity for range training, tactical reloads, and high-volume target shooting.
Constructed from a proprietary Technapolymer housing, the GLK-A9B is lightweight, impact-resistant, and built to withstand aggressive mag drops on dirt and range benches. Inside, an injection-molded polymer follower is driven by a heat-treated chrome silicon wire spring to maintain positive, uniform follower pressure through all 18 rounds.
Engineered for cross-platform compatibility across double-stack 9mm Glock models, the GLK-A9B extends slightly beyond the grip frame on Glock 17s, providing a comfortable additional finger extension when inserted into compact Glock 19 or subcompact Glock 26 grip wells.
Armorer Bench Notes & Real-World Staging Guidance:
Fitment Matrix: Fits double-stack 9mm Glock models, including Glock 17, 19, 19X, 26, 34, and 45 (Generations 1 through 5), as well as 9mm Pistol Caliber Carbines accepting standard double-stack Glock magazines. (Not compatible with single-stack models such as Glock 43, 43X, or 48).
- Perform a complete firearm safety check: drop the magazine, lock the slide rearward, and visually inspect the chamber to verify zero live rounds are present.
- Inspect the feed lips, follower movement, and outer polymer body of the new ProMag assembly prior to initial loading.
- Load up to 18 rounds of standard 9mm Luger ammunition into the magazine, using a magazine loader to assist with spring resistance on final rounds.
- Insert the magazine into the firearm magwell until the factory magazine release catches securely with an audible click.
- Depress the magazine release button to confirm smooth, drop-free ejection during tactical training drills.
