Crimson Trace LG-307 Lassergrips

• Instinctive Activation: The front pressure pad turns the laser on as the revolver is gripped normally, so the sight is ready without changing hand position or adding extra steps under stress.
• Grip Replacement Design: The LG-307 replaces the factory grip panels, keeping the laser integrated into the handgun rather than adding bulk to the frame or rail area.
• Rubber Overmold Construction: The rubber grip surface improves purchase and comfort, which is especially useful on heavier-recoiling revolvers where control matters as much as aiming speed.
• Windage and Elevation Adjustment: User-adjustable alignment allows the laser to be tuned to the revolver and chosen load, helping maintain a practical point of aim at typical defensive distances.
• 0.50 MOA Dot Size: A fine aiming point supports more precise shot placement than a large splashy dot, making the laser useful for both close defensive work and careful sight confirmation.

About the Lasergrips Series

Crimson Trace Lasergrips are built as grip-integrated laser sights for handguns, combining aiming assistance with a form factor that stays close to the original handling of the firearm. Within the company’s laser-sight lineup, the series sits alongside Laserguard and Rail Master models, but it is distinct in the way it replaces the grip itself rather than attaching externally to the trigger guard or accessory rail. That approach appeals to shooters who want a cleaner profile, secure fit and controls that feel natural from the first presentation.

A defining feature of the series is Instinctive Activation, which places the pressure pad where it can be engaged by a normal firing grip. In practical use, that means the laser comes on without a separate conscious action, helping the shooter stay focused on target acquisition. Depending on the handgun pattern, Lasergrips models are offered for defensive carry, duty use and revolver applications, with configurations shaped around the host firearm. The series is known for its grip-integrated construction, practical ergonomics and emphasis on fast sighting in low light or unconventional shooting positions where iron sights may be slower to align.

About the Crimson Trace LG-307 Lassergrips

The Crimson Trace LG-307 Lassergrips are designed for Smith & Wesson K and L-Frame square butt revolvers, giving these full-size revolvers an integrated red laser sight without changing their basic balance or manual of arms. Because the unit is built into a replacement grip, it avoids the added width and mounting complexity that can come with external handgun lasers. That makes it a practical fit for shooters who want a revolver to remain streamlined while gaining a faster visual aiming reference.

This model uses a 633 nm Class 3R red laser with front Instinctive Activation, so the beam engages as the revolver is gripped in a normal firing hold. That matters in defensive or field use, where speed and consistency are more important than operating extra switches. The rubber overmold grip adds another practical advantage by improving comfort and purchase, particularly on large-caliber revolvers where recoil control affects follow-up shots. Windage and elevation adjustment let the laser be matched to the revolver’s point of impact, while the fine 0.50 MOA dot supports deliberate aiming rather than covering too much of the target. In use, the LG-307 works well for low-light shooting, target indexing from awkward positions and faster sight confirmation when the shooter cannot bring the revolver fully up to eye level.

About Crimson Trace

Crimson Trace was established in 1994 and focuses on aiming and illumination products for firearms. The company is best known for firearm laser sights and firearm-mounted lights, with product families that include Lasergrips, Laserguard and Rail Master, while the Lightguard line covers dedicated weapon lights. One of its most recognizable design ideas is Instinctive Activation, which uses pressure pads positioned so the laser engages with a normal firing grip rather than a separate control sequence. In addition to handgun laser systems, Crimson Trace also offers riflescopes and rangefinders, showing a broader presence across shooting optics and accessories. The company operates a facility in Columbia, Missouri, United States.
