LaserMax LMSG517 Guide Rod Laser - 5mW Red Laser (635nM) for Glock 17, 17 MOS, 34 MOS Gen5 - Durable Aluminum Construction

The LaserMax LMSG517 Guide Rod Laser is a 5mW red laser (635nM) built into a durable aluminum guide rod assembly for Glock 17, 17 MOS, and 34 MOS Gen5 models. Unlike rail-mounted or slide-mounted lasers, this guide rod laser installs invisibly inside your pistol—replacing the factory spring and guide rod assembly without any permanent modifications to your gun. It's a clean, permanent upgrade that gives you laser aiming capability while keeping your slide profile unchanged. Whether you're training to improve hits under pressure or building a defensive carry setup, the LaserMax gives you a visual reference point that builds confidence and accuracy when it counts.

The on/off switch is ambidextrous, meaning you can activate the laser from either side of the gun—critical for both right and left-handed shooters and for tactical scenarios where your support hand might be occupied. The compact aluminum construction is built to handle carry and training use without adding bulk or weight to your pistol. Installation is straightforward: you're simply swapping your factory spring and guide rod for the LaserMax version, so there's no gunsmithing, permanent alteration, or return-to-factory headaches if you ever want to remove it.

This is a purpose-built tool for shooters who want the benefits of laser aiming without the external footprint of a mounted light-laser combo or a separate laser sight. If you run a stock Glock 17, 17 MOS, or 34 MOS Gen5 and want to add laser capability without changing how the gun looks or handles, the LaserMax guide rod laser is a straightforward, durable solution.
