Significant Capacity Increase
Adding six rounds to standard G17 17-round magazines brings total capacity to 23 rounds, while adding five rounds to G22 15-round magazines reaches 20 rounds—substantial capacity increases that reduce reload frequency during competition stages, training drills, or defensive scenarios. This additional ammunition capacity provides tactical advantages without requiring backup magazines or reducing the reliability expected from OEM Glock magazines. The extension maintains compatibility with existing magazines rather than requiring investment in new higher-capacity alternatives.
Steel Locking Plate Security
The included steel locking plate features a hook design that provides superior locking security compared to standard magazine base plate retention systems. This enhanced security proves critical when magazines are fully loaded with the additional rounds—ensuring the base plate remains securely attached even during hard magazine insertions, drops, or rough handling. The steel construction resists deformation and wear better than polymer alternatives, maintaining secure lockup through thousands of loading cycles and magazine changes.
Low Drag Reload Optimization
The low drag, no snag design facilitates smooth magazine insertion and withdrawal from magazine pouches, pockets, or carriers. The streamlined profile eliminates catch points that can slow reloads or cause magazines to hang up during extraction from carriers—critical considerations for competition where fractions of a second matter or defensive scenarios where rapid reloads under stress are essential. The smooth contours also reduce wear on magazine pouches and carriers compared to extensions with aggressive or protruding features.
Enhanced Grip and Control
The extended magazine plate increases the gripping surface available during magazine manipulation, improving control during reloads and magazine handling. This additional surface area proves particularly valuable when wearing gloves, in wet conditions, or during rapid reloads under stress where positive magazine control matters. The enhanced grip also facilitates magazine stripping from pistols during emergency or tactical reloads, allowing more confident manipulation without fumbling.
Competition-Legal Dimensions
Designed to fit USPSA 140mm Race Division limits, this extension allows competitors to maximize capacity while remaining within competition rules. This dimension compliance eliminates concerns about disqualification due to oversized magazine extensions, allowing shooters to focus on performance rather than equipment legality. The design demonstrates Strike Industries' understanding of competition requirements and shooter needs within organized shooting sports.
Broad Magazine Compatibility
Works with Glock G17 and G22 OEM double stack magazines as well as aftermarket ETS magazines, providing flexibility for shooters who mix OEM and aftermarket magazine inventories. Compatibility with Magpul and JP Enterprise magwells ensures the extension doesn't create fitment issues with popular magazine well accessories. This broad compatibility reduces the risk of discovering fitment problems after purchase and allows the extension to work across your existing magazine collection.
Impact-Resistant Durability
The impact-resistant polymer construction withstands the drops, impacts, and rough handling that magazines experience during competition, training, and field use. This material durability ensures the extension maintains its structural integrity and continues protecting the extended spring and locking plate even after being dropped on concrete, struck against hard surfaces, or subjected to the mechanical stresses of thousands of magazine changes. The polymer also resists chemicals from cleaning solvents and environmental exposure.
Complete Installation Kit
Including the extended spring, steel locking plate, and installation hardware eliminates the need to source additional components. The extended spring maintains proper tension with the increased capacity, ensuring reliable feeding of all rounds. The complete kit approach allows immediate installation and use without hunting for compatible springs or retention hardware—a convenience that saves time and ensures proper component matching.
Follow safe handling practices and manufacturer instructions for installation and use. Do not overtighten the steel locking plate set screw—when flush with the EMP body, no additional tightening is required to prevent product damage. The steel locking plate may appear loose when properly installed. Compatible only with Glock G17 and G22 double stack magazines—verify compatibility before purchase. Check local laws regarding magazine capacity restrictions before use. Ensure compliance with all applicable federal, state, and local laws.
