Strike Industries SI-G4 Modular Magazine Release Glock Gen 4/5 Red

The Strike Industries Modular Magazine Release (SI-G4) is a drop-in upgrade for the magazine catch on most Glock Gen 4 and Gen 5 pistols. CNC-milled from 6061 aluminum with a bright red anodized finish, the release ships with two interchangeable push-button faces so the user can swap profiles without removing the assembly from the frame.

Both button faces carry aggressive texturing to keep magazine drops positive and consistent, even with wet or gloved hands. The internal release bar is molded from high-density polymer for smooth ejection, and installation is a direct swap using standard armorer tools.

Engineered to fit most Glock Gen 4 and Gen 5 handguns, including the G17, G19, G19X, G45, G22, G23, G26, G27, G31, G35, G37, and G39.

Package includes: one assembled magazine release with two interchangeable 6061 aluminum push buttons.
