Crimson Trace LG-420 LaserGrips Red Laser for Sig Sauer P220

The Crimson Trace LG-420 LaserGrips transform the Sig Sauer P220 into a precision instrument with instinctive laser activation. This red laser sight system replaces the standard grip panels while maintaining the pistol's original ergonomics and balance.

What Makes This Different

Unlike rail-mounted laser systems that add bulk and alter the weapon's profile, the LG-420 integrates seamlessly into the P220's grip frame. The patented Instinctive Activation technology engages the laser automatically when the pistol is gripped naturally, eliminating fumbling for separate switches during high-stress situations. The system delivers consistent 50-yard accuracy with a 0.5-inch dot at 50 feet, surpassing many external laser attachments in both precision and reliability.

Key Features

• Instinctive Activation - laser activates with natural grip pressure
• Red laser wavelength 630-670nm with 5mW maximum output
• Windage and elevation adjustment screws for precise zeroing
• Polymer construction with textured grip surface for enhanced control
• Master on/off switch prevents accidental activation during storage
• Four-hour continuous runtime on single 1/3N lithium battery
• Drop-tested to military specifications for impact resistance

Field testing demonstrates reliable function in temperatures from -10°F to 120°F, with the laser maintaining zero through hundreds of firing cycles. The system proves particularly effective for low-light defensive scenarios and precision shooting applications where rapid target acquisition matters. Competition shooters report faster first-shot times, while law enforcement agencies appreciate the tactical advantage during building searches and vehicle stops.
