Crimson Trace LG-660 Lasergrips

• Instinctive rear activation: the laser engages as the pistol is gripped in a normal firing hold, so the sight is available immediately without adding a separate step to the draw or presentation.
• Grip-integrated Lasergrips design: this unit mirrors the shape and feel of the factory grip, preserving familiar handling while adding a visible aiming reference for defensive or duty use.
• User-adjustable windage and elevation: point of impact can be tuned to the pistol and ammunition, helping the laser track the handgun’s real-world zero rather than forcing a one-size-fits-all setup.
• 5 mW Class 3R red laser: the red aiming point gives fast visual confirmation at typical handgun distances, supporting quicker sight indexing in low light and from unconventional shooting positions.
• Interchangeable across supported M&P full-size calibers: the same grip unit fits multiple compatible full-size variants, making it practical for shooters running more than one pistol in the same platform.

About the Lasergrips Series

Crimson Trace Lasergrips are built around a simple idea: add a laser sight to a handgun without changing the way the pistol is held, drawn or indexed. In the Crimson Trace lineup, the series sits as a dedicated grip-integrated solution for shooters who want a cleaner installation than rail-mounted units and who prefer the laser to become part of the handgun’s normal handling. The defining feature of the range is Instinctive Activation, which places the activation control where it can be engaged by a natural firing grip rather than by a separate button press.

Across the series, Lasergrips are intended for defensive handguns, duty pistols and everyday carry applications where fast target indexing matters. Their design philosophy focuses on maintaining the pistol’s original feel while adding an aiming aid that remains useful in low light, from retention positions, or when the shooter cannot obtain a full sight picture. Depending on the model, the line covers revolvers and semi-automatic pistols with different activation layouts, grip materials and fit patterns, but the common thread is a grip-mounted laser system that keeps the handgun compact and familiar in the hand.

About the Crimson Trace LG-660 Lasergrips

The Crimson Trace LG-660 Lasergrips are designed for the Smith & Wesson M&P Full-Size platform, giving that pistol a laser sighting system without adding bulk to the dust cover or changing the manual of arms. Because the unit directly replaces the grip and closely follows the original profile, it keeps the handgun’s handling familiar for shooters who already know the M&P layout. That matters on a defensive pistol, where consistency in grip shape and activation can be more important than adding extra controls.

The key feature is rear Instinctive Activation. As the pistol is gripped in a normal firing hold, the laser comes on without the shooter needing to search for a side switch or alter hand placement. In practice, this supports faster target indexing during rapid presentation, especially in low light or when shooting from compromised positions where the iron sights are harder to align. The red 633 nm laser operates in laser-only mode and projects a fine aiming point, with the listed 0.50 MOA dot size helping keep the reference precise at typical handgun distances.

The LG-660 also includes windage and elevation adjustment, allowing the laser to be matched to the pistol and chosen load. That makes it more useful than a fixed unit when the goal is practical point-of-impact alignment. Its retractable polymer construction keeps weight and bulk under control, while the integrated on/off switch allows the user to disable the laser when required for training, storage or administrative handling.

About Crimson Trace

Crimson Trace was established in 1994 and built its reputation around aiming and illumination products for firearms. The company’s core expertise includes firearm laser sights and firearm-mounted lights, with product families such as Lasergrips, Laserguard and Rail Master covering different handgun and long-gun mounting styles. Crimson Trace also produces riflescopes and rangefinders, giving it a broader presence across shooting optics as well as accessory aiming systems.

A defining part of the brand’s identity is Instinctive Activation, which uses pressure pads positioned to work with a normal shooting grip rather than requiring a separate deliberate press. That approach is especially relevant to handgun laser products, where speed and consistency matter. Crimson Trace operates a facility in Columbia, Missouri, United States, and its catalog remains closely focused on practical sighting and lighting tools for defensive, sporting and field firearms use.
