The Viridian E SERIES Red Laser Sight for Glock 42/43/43X/48 delivers rapid target acquisition for everyday conceal and carry, offering a powerful red laser mounted on the trigger guard for quick and accurate aiming. Designed for easy installation, the compact sight securely fits Glock models and provides an ambidextrous on/off button with a 5-minute auto shut-off to conserve battery life, ensuring ready use when you need it most. With a documented 25-yard performance in daylight and an impressive reach of up to a mile at night, this laser sight enhances shot placement across lighting conditions while maintaining a comfortable concealed carry profile. The Viridian laser operates with a constant beam and delivers more than six hours of continuous runtime, supported by straightforward windage and elevation adjustments for precise zeroing. Although optimized for Glock 42/43, it also fits the Glock 43X and 48, with the important caveat that it does not fit the 43X MOS variant. Built for reliability and fast acquisition, the Viridian E SERIES red laser sight is a practical enhancement for home defense, duty, or recreational shooting, merging intuitive use with durable, purpose-built performance.
