Crimson Trace LG-420G Green Laserguard for Sig Sauer P320/M17/M18

The Crimson Trace LG-420G Green Laserguard transforms target acquisition speed for Sig Sauer P320, M17, and M18 pistols. This precision laser sight delivers instant target illumination in daylight conditions where red lasers struggle to maintain visibility.

What Makes This Different

Green laser technology operates at 532nm wavelength, providing up to 5x greater visibility than traditional red lasers in bright conditions. The integrated trigger guard design eliminates the need for rail space while maintaining the pistol's original profile. Instinctive activation responds to natural firing grip pressure, engaging the laser automatically without conscious thought or grip modification.

Key Features

• Green laser visibility effective to 100 yards in daylight conditions
• Instinctive activation triggered by natural firing grip pressure
• Integrated trigger guard mount preserves rail space for accessories
• Master On/Off switch prevents accidental activation during storage
• Windage and elevation adjustments with included hex wrench
• Polymer construction with matte black finish matches factory aesthetics
• Compatible with most holsters designed for standard P320 series

Field testing demonstrates consistent zero retention through 500+ round sessions. The laser maintains accuracy within 2-inch groups at 25 yards across temperature variations from -10°F to 120°F. Law enforcement and competitive shooters report faster target transitions and improved accuracy in low-light scenarios. The unit's low-profile design integrates seamlessly with duty gear and concealed carry applications.
