Genuine Glock Factory Magazines: The Standard for Gen 3 & 4 Reliability
When your life or your performance at the range depends on it, there is no substitute for a Glock Factory Magazine. While aftermarket options exist, only Genuine OEM Glock Magazines are engineered to the exact tolerances of your firearm.
Designed specifically for Gen 3 and Gen 4 Glock models, these magazines feature the legendary “over-engineered” construction that has made Glock the world’s most trusted sidearm.
Why Choose OEM Glock Factory Magazines?
Glock magazines are famous for being “indestructible,” but their true value lies in their internal architecture.
-
Hardened Steel Inserts: Every factory magazine is built with a stiff steel frame encased in high-tech polymer. This prevents the magazine from deforming, even when dropped on concrete or used in extreme temperatures.
-
Gen 4 Compatibility: These magazines feature the dual-cut notch, making them fully compatible with the reversible magazine catch found on Gen 4 frames, while remaining backwards compatible with Gen 3 models.
-
Low-Friction Followers: Precision-molded followers ensure smooth, consistent feeding of every round, from the first to the last.
-
Extreme Durability: The polymer coating protects the steel core from corrosion and provides a slick surface for lightning-fast reloads.

Engineered for Perfection
Glock Factory Magazines are designed to be “drop-free,” meaning they eject cleanly from the magwell every time the release is pressed. The high-quality leaf springs are factory-set to maintain their tension over years of use, ensuring that whether your magazine is full or near-empty, the upward pressure remains constant.
Don’t Compromise on Your Carry Gear
For everyday carry (EDC) or professional duty, aftermarket magazines are for practice—Glock Factory Magazines are for performance. Ensure your Gen 3 or Gen 4 Glock runs exactly as the engineers intended by using only genuine factory parts.
