Crimson Trace LG-489G Green Laserguard for S&W M&P Shield

The Crimson Trace LG-489G Green Laserguard transforms the Smith & Wesson M&P Shield into a precision instrument with instant target acquisition capabilities. This laser sight system activates with natural grip pressure, eliminating fumbling for switches during critical moments. Green laser technology provides superior visibility in daylight conditions compared to traditional red lasers.

What Makes This Different

Green laser diodes produce wavelengths that appear significantly brighter to the human eye than red alternatives, offering up to 5x greater visibility in bright conditions. The instinctive activation system responds to proper shooting grip without requiring conscious thought or finger manipulation. Unlike rail-mounted lasers that add bulk, this unit integrates seamlessly with the M&P Shield's trigger guard profile. Activation occurs automatically when the firearm is gripped correctly, providing consistent laser projection without training modifications.

Key Features

• Green laser diode provides enhanced daylight visibility over red laser systems
• Instinctive activation engages with proper shooting grip pressure
• Fits Smith & Wesson M&P Shield 9mm and .40 S&W models
• Windage and elevation adjustments for precise zero alignment
• Polymer construction maintains lightweight carry profile
• Compatible with most holsters designed for M&P Shield
• Four-hour auto shutoff conserves battery life during extended carry

The LG-489G maintains zero through extended shooting sessions and carries comfortably without printing or snagging. Law enforcement agencies report improved accuracy during low-light training scenarios, while competitive shooters appreciate the consistent dot placement for rapid target transitions. The unit withstands recoil forces from standard and +P ammunition loads without shifting point of impact. Weather-resistant construction handles moisture and temperature variations encountered during daily carry.
