Description
The LaserMax LMS-1131G is an internal guide rod laser engineered specifically for Glock 19, 23, 32, and 38 pistols in Gen 1-3 configurations. It installs in minutes by replacing the pistol’s factory recoil spring guide assembly – no gunsmithing required – and delivers a high-intensity green aiming point for fast target acquisition in any lighting.
The unit emits at a 520nm wavelength with a 5mW output for a bright, highly visible dot that performs well in varied conditions. Practical effective range is 20 yards in daylight and up to 300 yards at night, with a tight .31″ dot at 7 yards for precision work. The on/off switch is integrated into the takedown lever, providing ambidextrous activation that follows the natural manipulation of the slide. A user-programmable control lets the shooter switch between a pulse or steady beam to match the environment and personal preference.
Because the laser lives inside the slide as the guide rod, it preserves the factory profile of the pistol – there are no external mounts, no holster modifications, and no snag points. The LMS-1131G is designed and assembled by LaserMax as a drop-in enhancement for compact and subcompact service pistols in the Glock lineup.
