Compatibility & Fitment Guidance
This mag release is intended for most Glock Gen4 and Gen5 frames. Because Glock platforms have various frame generations and aftermarket modifications, we recommend:
Confirm your frame generation (Gen4 or Gen5) before ordering.
Check for prior frame modifications (e.g., stippling, frame cuts, or third-party mag catch changes) — heavily altered frames may require gunsmith installation.
Test function after installation to ensure positive engagement and reliable magazine ejection.
Installation Overview
Installing the Strike Industries Modular Mag Release is straightforward for those familiar with basic pistol maintenance. Typical steps include:
Safely unload the firearm and clear all ammunition from the work area.
Remove the slide and take down the pistol per manufacturer instructions.
Replace the factory mag release with the Strike Industries unit (installation may require a small punch and screwdriver).
Reassemble and perform live-fire function checks to confirm reliable release and fit.
If you’re not comfortable installing firearm parts, have a qualified gunsmith perform the swap. Never attempt installation on a loaded firearm.
Maintenance & Care
Clean with a soft cloth and mild solvent if necessary; avoid abrasive cleaners that can damage the anodize.
Periodically inspect for wear and ensure screws or retaining pins (if used) are secure.
Keep mag release area free of excessive carbon buildup and debris for reliable function.
