Benefits & Performance
Faster Reloads: The enlarged, textured surface gives your thumb a predictable purchase point — reducing time to magazine release and improving reload consistency.
Customizable Feel: Modular architecture allows future swaps or accessory paddles to dial in the exact size and shape you prefer.
Durable & Lightweight: Aircraft-grade aluminum keeps weight low while providing superior strength and resistance to deformation.
Low-Profile for Concealment: Designed to improve function without significantly increasing printing or snag risk during carry.
Aesthetic Upgrade: Vibrant red anodize adds a distinctive look to custom builds while protecting the metal surface.
Compatibility & Fitment Guidance
Intended for most Glock Gen4 and Gen5 frames. Because some frames are heavily modified (aggressive stippling, frame cuts, aftermarket mag catch changes), verify fitment on your specific pistol.
If you own aftermarket frames or have had gunsmithing performed, check one magazine/frame before purchasing a set.
Works best with magazines and mag-catch geometries that adhere to Glock dimensional standards.
Installation — Fast & Simple
Safety first: Clear the firearm and ensure it is unloaded. Work in a safe area.
Remove the factory magazine release by pushing out the retaining pin and sliding the catch assembly out (follow Glock manufacturer guidance).
Install the Strike Industries release in the reverse order; ensure the catch engages the magazine follower properly.
Perform an unloaded function check: insert magazines, confirm seating and lock-back, and press the release to verify positive drop.
If you’re not comfortable performing the swap, have a qualified gunsmith install it for you.
Maintenance & Care
Low maintenance: Wipe down with a dry or mildly damp cloth to remove dirt and oils.
Avoid harsh solvents: While anodize is robust, prolonged exposure to aggressive chemicals can shorten its life.
Inspect periodically: Check for looseness or wear after heavy use — aluminum is durable, but components endure stress over time.
Swapability: The modular platform makes upgrades or color changes quick and easy.
Who Should Upgrade?
Competition shooters aiming to shave fractions of a second off reloads.
Concealed carriers who want improved ergonomics without adding bulk.
Duty / security personnel seeking durable, reliable controls.
Custom Glock builders who value both function and aesthetic personalization.
Safety & Legal Notes
Modifying firearm controls may change how your pistol handles. Always follow safe firearm handling procedures and conduct comprehensive function testing in a safe environment before carrying or relying on the pistol for duty or defense.
Verify compliance with local, state, and federal laws before modifying or transporting firearms. If unsure about fitment, installation, or functionality, consult a certified gunsmith.
