Strike Industries Modular Magazine Release Glock Gen4-5 Black Aluminum

The Strike Industries SI-G4 Modular Magazine Release is an aftermarket drop-in upgrade designed for most Glock Gen4 and Gen5 pistols. The release uses a hybrid construction, pairing two interchangeable CNC-milled 6061 aluminum push buttons with a lightweight high-density polymer body bar that resists wear on the magazine well's polymer retention cut-outs while keeping ejection smooth under repeated use.

The modular design lets the shooter swap between two aggressively textured button faces to match personal preference or shooting style, while the polymer internal mechanism is built for reliable magazine drop under pressure. The aluminum buttons are finished in black to coordinate with factory slide and frame finishes on most Gen4 and Gen5 Glock handguns.

Installs in place of the factory magazine release with no permanent modifications required. Each kit ships with two CNC-milled aluminum push buttons and the polymer body bar, ready to drop into most Glock Gen4 or Gen5 pistols.
