The LaserMax LMS1141G Green Guide Rod Laser is a compact aiming solution built directly into your Glock's guide rod—no external attachments, no holster conflicts, no gunsmithing required. Designed for Glock 17, 22, 31, and 37 pistols in generations 1–3, this green laser gives you rapid target acquisition and aim confirmation in low-light and dark conditions, from indoor defensive scenarios to outdoor range time after sunset.
Unlike mounted or gripped lasers, the LaserMax guide rod design keeps your pistol's profile unchanged. Field-strip your Glock, swap in the laser-equipped guide rod, and you're done—no special tools or gunsmith visits needed. The laser is factory pre-aligned at 20 yards and requires no re-zeroing after battery changes, so your point of aim stays consistent across all shooting distances. Ambidextrous activation is integrated into a custom take-down lever that feels and functions like your factory controls, so the learning curve is flat.
Built to military and Homeland Security durability standards, this laser has survived drop tests, abrasive conditions, temperature swings, saltwater exposure, and deep-water submersion—plus 20,000+ rounds of live fire testing. The 5mW green beam at 520 nanometers is visible from 20 yards in daylight and effective out to 300 yards at night, delivering the situational awareness you need when seconds count. The pulsing beam mode enhances visibility and provides unmistakable muzzle awareness in any environment.
If you carry a Glock 17, 22, 31, or 37 for duty, sport, or self-defense and want to add laser aiming without changing your holster or handling, the LaserMax green guide rod laser is a no-fuss upgrade that stays where it belongs—inside the gun.

Frequently Asked Questions
Will the LaserMax guide rod laser work with my current holster?
Yes. Because the laser is completely internal to the guide rod, it doesn't change your pistol's external dimensions or profile. Your existing holster will fit without modification.
Can I install this myself, or do I need a gunsmith?
No gunsmith required. If you can field-strip your Glock, you can install the LaserMax guide rod laser. Simply replace the factory guide rod with the laser-equipped version during your normal disassembly.
Do I have to re-zero the laser after changing the battery?
No. The laser is factory pre-aligned at 20 yards and maintains that alignment even after battery changes, so your point of aim remains consistent.
What does the pulsing beam do?
The pulsing beam mode makes the laser more visible and provides a clear muzzle awareness cue, especially useful in low-light conditions. The beam also transcends language barriers, making muzzle direction obvious to anyone nearby.
