The Crimson Trace LG-499 Green LaserGuard delivers instant target acquisition for Heckler & Koch VP9, VP9SK, and VP40 pistols. This trigger guard-mounted laser sight provides precise aiming capability in all lighting conditions while maintaining the pistol's original profile and handling characteristics.
What Makes This Different
Unlike traditional rail-mounted lasers, the LG-499 integrates seamlessly into the trigger guard without adding bulk or interfering with holster compatibility. The green laser technology offers 5x greater visibility than red lasers in daylight conditions. Instinctive activation occurs naturally during the shooting grip, eliminating fumbling for separate switches under stress.

- Compatible with most existing holsters designed for VP9/VP9SK/VP40
