The LaserMax Green Glock Guide Rod Laser For Glock 20/21/41 Gen4 replaces the factory recoil spring guide with a compact, high-intensity green laser sighting system. Fully contained inside the pistol, it preserves the original profile of Glock Gen4 models 20, 21, and 41 while delivering a bright, pulsing beam for confident target acquisition in a wide range of lighting conditions.

This guide rod laser is ideal for shooters who want an unobtrusive aiming aid for training, range use, or home protection without changing holsters or adding bulk to the handgun. Installation is straightforward and requires no gunsmithing, making it a practical upgrade for both new and experienced Glock owners. Precision construction with aircraft-grade aluminum and genuine Wolff springs reflects LaserMax’s focus on reliability and thoughtful engineering.
