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

The Crimson Trace LG-637 Lasergrips transform Glock pistol accuracy with instinctive activation laser sighting. This red laser sight system integrates directly into the pistol grip, eliminating the need for rail-mounted accessories while maintaining the firearm's original profile and holster compatibility.

What Makes This Different

Unlike rail-mounted laser systems, the LG-637 replaces the factory grip panels with laser-equipped grips that activate through natural grip pressure. The instinctive activation technology engages the laser automatically when the shooter establishes a firing grip, requiring no conscious thought or button manipulation. This design maintains the pistol's balance and eliminates snag points common with external laser attachments.

• Red laser dot visible to 50 yards in daylight conditions
• Compatible with Glock Gen 3, 4, and 5 full-size models (17, 22, 31, 37)
• Maintains original holster compatibility with factory grip dimensions

• Polymer construction matches Glock frame durability standards

The LG-637 performs consistently across temperature ranges from -10°F to 120°F, making it suitable for duty carry, competitive shooting, and home defense applications. The laser dot remains visible in indoor lighting conditions and provides rapid target acquisition in low-light scenarios where iron sights become difficult to align. Battery life extends beyond 4 hours of continuous operation with standard lithium batteries.
