Crimson Trace LL803 Laserguard Pro 5mW Red Laser & 150 Lumens LED Light for Glock 43/42/48/43X (Non-Railed)

The Crimson Trace LL803 Laserguard Pro pairs a 5mW red laser with 150 lumens of LED white light in a single, compact unit built specifically for the Glock 43, 42, 48, and 43X (non-railed). If you carry a slim, concealable pistol and want the advantage of both targeting precision and illumination in one tool, this is a no-compromise addition that activates the moment you grip the gun—no fumbling for switches when seconds count.

Instinctive Activation™ is the standout here: the unit powers on with your normal firing grip, so muscle memory takes over when it matters. You get four operating modes—laser only, light only, laser plus light, and laser plus light strobe—so you can dial in exactly what the situation demands, whether that's a dark-home-defense scenario, range time, or identifying a threat at distance. The laser is factory-sighted at 50 feet and adjustable for windage and elevation, meaning you can zero it to your point of aim without guessing.

Installation is straightforward: no gunsmithing, no special tools beyond the included wrench—you'll be ready to go in minutes. The 2-hour battery life is solid for a carry gun that sees frequent training or duty use, and the compact design won't add unnecessary bulk to an already slim platform. For anyone carrying a Glock 43-series pistol who wants better target acquisition and situational awareness, the LL803 delivers both without compromise.
