The Crimson Trace LL-803G is a green laser sight built for the Glock 42, 43, 43X, and 48, mounting directly to the trigger guard for a sight picture that is ready the instant the pistol comes up. The unit is factory-sighted at 50 feet and ships adjustable for windage and elevation, so zeroing to point of aim takes only a few clicks. (brand part no. 01-5860-1) A built-in 150-lumen white LED shares the housing with the laser, so the same activation switch delivers both illumination and an aiming reference in one unit.

Key Specifications

• Mount type is a trigger guard replacement, so installation takes minutes with no gunsmithing.
• Laser color is green, for better daylight visibility than a standard red diode.
• Output power is rated at 5mW, the maximum legal output for a consumer laser sight.
• Dot size is approximately 0.5-inch at 50 feet, wide enough to find quickly without washing out the target.
• Integrated light adds a 150-lumen white LED, for target identification in the same housing as the laser.
• Activation is Instinctive Activation, so the laser powers on automatically from a normal firing grip, with no separate switch to remember.
• Fit is dedicated to the Glock 42, 43, 43X, and 48, for a factory-matched contour with no gap or rattle.
• Construction uses a black polymer housing, built to hold zero through normal carry and range use.

Is this a permanent modification? No, it replaces the factory trigger guard as a drop-in unit and can be removed to restore the original setup.

Can the point of aim be adjusted? Yes, the laser is user-adjustable for windage and elevation so it can be zeroed to the gun’s actual point of impact.
