Crimson Trace LG637G Lasergrips - Black, Green Laser 5mW, 633nM Wavelength, Compatible with Glock Gen3-5 Handgun Grip Mount

The Crimson Trace LG637G Lasergrips bring modern aiming precision to your Glock, mounting seamlessly as a grip replacement on Gen3, Gen4, and Gen5 full-size models. Green lasers cut through poor lighting and clutter better than red, and at 5mW output with a 633nM wavelength, this sight pairs solid performance with a form factor that doesn't add bulk or weight to your carry gun. Whether you're running a home defense Glock, training at the range, or carrying professionally, these grips integrate the laser into your grip purchase rather than bolting on another accessory.

Lasergrips work by feel—once you're familiar with how your trigger finger naturally aligns with the laser activation pad on the grip panel, target acquisition becomes intuitive. In low light or defensive scenarios where your sights might wash out or blur, a laser dot gives you a secondary aiming reference and potential deterrent value. The green laser is especially useful indoors or in mixed lighting where a red dot can be harder to spot.

These are true grip replacements: you remove your factory panels and install the Lasergrips as your new grip surface. No holster modifications needed (though you may want to verify fit with your carry gear). Battery life and maintenance are straightforward—this is proven Crimson Trace engineering without gimmicks.

Frequently Asked Questions

Will these Lasergrips work with my Glock Gen5 pistol?

Yes—the LG637G is designed to fit Glock Gen3, Gen4, and Gen5 full-size models. Verify your specific model before purchase, as these are not compatible with compact or subcompact variants.

Do I need to change my holster for the Lasergrips?

Since these replace your grip panels rather than mounting on a rail or sight cut, most standard Glock holsters will still fit. However, the slightly different grip profile may require a test fit with your carry holster before relying on it in the field.

Why green laser instead of red?

Green lasers are easier for most eyes to track and remain visible in bright or mixed lighting conditions where red lasers can wash out. The 633nM wavelength on the LG637G provides a crisp, bright dot for target acquisition in low light or indoors.

How do I activate the laser?

The activation pad is integrated into the grip itself, so a natural grip typically engages the laser without requiring a separate button press or external switch. Once you're familiar with the grip, aiming becomes intuitive.
