Glock Factory Magazines with Pre-Installed Factory Extensions
Maximize your capacity without compromising on “Glock Perfection.” Our Glock Factory Magazines with Factory Extensions provide the perfect balance of increased round count and 100% OEM reliability. Unlike aftermarket “plus-baseplates” that can cause spring tension issues, these magazines are factory-engineered to ensure consistent feeding and flawless slide lock-back.
Whether you are looking for a +2 extension for your Glock 17/19 or an extended grip for your subcompact Glock 26, these genuine magazines are the professional’s choice for duty and defense.
The Advantage of Glock OEM Extensions
When you choose a factory-extended magazine, you are getting a system designed by the same engineers who built your pistol.
-
Enhanced Grip Surface: For subcompact models like the Glock 26 or 27, the factory extension provides a crucial “pinky rest,” significantly improving recoil control and accuracy.
-
Hardened Steel Inserts: Just like standard mags, these feature a steel internal tube encased in Glock’s high-tech polymer to prevent bulging and ensure drop-free performance.
-
Optimized Spring Tension: Factory-extended magazines utilize the correct spring weight to accommodate the extra rounds, preventing the “last round” feeding failures common in DIY extensions.
-
Increased Firepower: Most 9mm and .40 S&W factory extensions add +2 rounds to your standard capacity, giving you the edge in high-stress situations.
