Crimson Trace LG-637 Lasergrips Red Laser Sight for Glock Gen 3/4/5 Full Size - Black Polymer

The Crimson Trace LG-637 Lasergrips is a grip-replacement laser sighting system purpose-built for Glock Gen 3, Gen 4, and Gen 5 full-size pistols. Designed as a direct-fit replacement for the factory side panels, the LG-637 features a black rubber-overmold polymer housing that contains an integrated red laser module, giving the shooter an intuitive aiming reference without adding bulk to the slide or changing holster fit.

Because the LG-637 replaces the existing grip panels rather than clamping to a rail or trigger guard, installation requires no permanent modification to the host pistol. The overmolded panels swap in for the factory grips and are secured using the original hardware, leaving the firearm's controls, iron sights, and magazine release fully functional.

The integrated laser runs at a 633nM wavelength with a 5mW output, producing a clearly visible red dot with a measured size of 0.50" at 50 feet and an effective range of approximately 50 feet. Both windage and elevation are user-adjustable, allowing the beam to be precisely zeroed to the host pistol's point of impact at a chosen distance.

Activation is handled by a pressure pad integrated into the front strap of the grip, so the laser comes on naturally when the shooter achieves a proper firing grip. A master on/off switch on the unit allows the laser to be disabled for storage or transport. Power is supplied by a single CR2032 battery housed inside the grip panel.
