LaserMax LMSG417 Guide Rod Laser 5mW Red 635nM Aluminum for Glock 17/34 Gen4

The LaserMax LMSG417 Guide Rod Laser is a red laser sight engineered for the Glock 17 and Glock 34 Gen4, designed for shooters who want rapid target acquisition without adding bulk or changing their familiar carry setup. Built inside the guide rod—the spring assembly that lives beneath the barrel—this 5mW red laser (635nM wavelength) stays completely hidden when your gun is holstered, leaving your grip, tactical light mounting, and holster compatibility untouched. That means no trade-offs: you keep the setup you trust and gain a proven aiming tool in one installation.

Installation is genuinely fast. If you can field-strip your Glock, you can swap in the LaserMax guide rod laser in minutes—no gunsmith, no permanent modification. The laser arrives pre-aligned at 20 yards and maintains that zero indefinitely; there's no need to recalibrate after a battery swap. Activation is handled through an ambidextrous lever built into the takedown mechanism, so both right- and left-handed shooters can operate the laser intuitively without repositioning their grip.

LaserMax built this laser to military and homeland security durability standards: it survives drop tests, sand, temperature swings, humidity, saltwater fog, deep water immersion, and 20,000+ rounds of live fire. The red pulsing beam cuts through low-light conditions—dusk to dawn outdoors, anytime indoors—and the visible pulse makes your point-of-aim instantly obvious to yourself and others. Positioning the laser as close as physically possible to the bore gives you the tightest bore-to-laser relationship available, which means the most consistent POA/POI spread across all shooting distances.

Frequently Asked Questions

Will the laser affect my holster fit or light mounting?

No. The LaserMax Guide Rod Laser sits completely inside the gun—you keep your existing holster, tactical lights, and grip panels without any compatibility issues.

Does this laser work outdoors and indoors?

Yes. The 5mW red pulsing beam is effective in low-light conditions—dusk through dawn outdoors—and works reliably indoors around the clock.

How do I install it, and will I need a gunsmith?

No gunsmith required. If you can field-strip your Glock 17 or 34 Gen4, you can install the guide rod laser yourself in minutes.

Does the laser stay zeroed after I change the battery?

Yes. The laser arrives pre-aligned from the factory and will never fall out of alignment, so there is no need to re-zero after battery changes.
