LaserMax LMSG43 Guide Rod Laser 5mW Red, 650nM Wavelength, Stainless Steel for Glock 43/48/43X

The LaserMax LMSG43 Guide Rod Laser is a 5mW red laser sighting system built into a stainless steel guide rod that replaces your Glock 43, 48, or 43X factory spring guide assembly. If you shoot a compact Glock and want to add an aiming reference without modifying the gun's externals or worrying about holster compatibility, this laser sits where the stock guide rod goes—no gunsmithing, no special tools needed. The 650nM red beam gives you a bright aiming point that tracks with your bore, and you get the option to run it steady or pulsing depending on your lighting conditions and preference.

Installation is straightforward enough for most shooters to handle at home. The laser is factory-aligned to standard Glock ballistics, so your point of aim and point of impact should track together out of the box. That matters when you're training or hunting—you need to trust your sighting system. The ambidextrous on/off switch is positioned for safe, intuitive handling from either hand, and the guide rod's internal design won't interfere with any holster or grip you're already using.

This is the kind of accessory that earns its carry weight for defensive shooters, range learners, and hunters who want a repeatable aiming reference without the bulk of a mounted optic. It's reliable, discreet, and purpose-built for the guns you already have.
