LaserMax LMSG517G Guide Rod Green Laser 5mW 520nM for Glock 17/17 MOS/34 MOS Gen5 Aluminum

The LaserMax LMSG517G Guide Rod Green Laser is a proven training and defensive aid for Glock 17, 17 MOS, 34 MOS, and Gen5 models. By integrating a 5mW green laser directly into your pistol's guide rod assembly, this system gives you an aiming reference that works under the stress and speed of real shooting—without permanent modifications to your gun. The green laser (520nM wavelength) is bright enough to use in low-light conditions and offers faster target acquisition than relying on sights alone.

Installation is straightforward: the LaserMax replaces your factory spring and guide rod assembly with no gunsmithing required. That means you can return your pistol to stock configuration anytime. The ambidextrous on/off switch works equally well for right- and left-handed shooters, and the aluminum construction keeps weight minimal while maintaining durability through regular carry and training.

Whether you're working through dry-fire drills at home, training at the range, or building a defensive carry setup, a guide rod laser teaches trigger control, sight alignment, and follow-up shots in a way that's hard to replicate. The green wavelength is easier on the eyes than red and typically visible in more ambient light conditions.
