Shield Arms Glock 17 9MM 22 Round Extended Magazine - Black - SKU: G17-ME-5INS-BLK - UPC: 810159260923
Product Description
The Shield Arms Glock 17 9mm 22-Round Extended Magazine (G17-ME-5INS-BLK) is a factory-assembled, pre-installed high-capacity feeding system engineered for dynamic USPSA/IDPA competition, tactical duty, and home defense staging. Combining a brand-new factory OEM Glock 17 17-round magazine body with a Shield Arms +5 billet aluminum magazine extension, this unit increases total capacity to 22 rounds of 9x19mm Luger without requiring end-user installation.
The extension body is precision CNC-machined from 6061-T6 aircraft-grade aluminum and finished in a matte black Type III hardcoat anodizing for maximum scratch, corrosion, and drop resistance. Designed with Shield Arms' fast access indexing grooves, the base pad allows shooters to strip stuck magazines efficiently during clearing drills. Its index-pin retention system ensures the extension remains locked onto the magazine rails under harsh recoil and drop impacts onto concrete.
Equipped with a pre-installed, high-tensile extended power spring, the G17-ME-5INS-BLK delivers continuous upward pressure against the factory follower to guarantee 100% feed reliability and positive slide lock-back on the final round.
*Armorer Bench Notes & Real-World Staging Guidance:
Fitment Matrix: Fits Glock 17, 34, 45, 19X, and 9mm Glock-pattern Pistol Caliber Carbines (AR-9, Ruger PC Carbine, etc.). Compatible with standard factory magwells and wide competition magwell funnels. (Check state and local capacity limits regarding 22-round magazines prior to purchase).
- Verify host firearm is completely clear, magazine removed, and chamber visually and physically confirmed empty.
- Load 9x19mm Luger cartridges smoothly into the magazine using a standard speed loader to manage spring tension up to the 22nd round.
- Insert loaded magazine firmly into the host firearm's magwell until the magazine catch engages with a distinct tactile click.
- Pull down on the baseplate extension to verify complete catch retention before racking the slide or dropping the bolt.
- To clean, loosen the baseplate locking pin using an Allen key and slide the base pad off the steel-lined mag housing.
