Crimson Trace LG443 Laserguard 5mW Red Laser Sight for Glock 43/42/48/43X - 633nM Wavelength, 50 ft Range, Black Finish

The Crimson Trace LG443 Laserguard is a compact red laser sight built specifically for Glock's slimline lineup—the G42, G43, G43X, and G48. If you carry a slim Glock for concealed work or home defense, this 5mW laser mounts directly to your pistol's trigger guard and activates the instant you grip the gun, no fumbling with separate buttons or switches. That instinctive activation means the laser comes on naturally as part of your normal shooting grip, giving you a fast aiming reference in low light or high-stress situations without changing your draw technique.

Installation takes just minutes with basic hand tools and no gunsmithing—the whole system tightens around the trigger guard and stays put. Once mounted, you get full user-adjustable windage and elevation to dial it in at your preferred distance. At 50 feet, the laser prints a half-inch group, tight enough for defensive accuracy at realistic handgun ranges. The 633nM wavelength delivers a bright red dot that's easy to pick up indoors or at dusk, and the battery lasts over four hours of continuous use, so you're not swapping cells every range trip.

The black finish matches your pistol and keeps things discreet, and there are no external levers or buttons to snag or get in the way of your holster. Whether you're training, competing in action shooting sports, or maintaining readiness for home defense, the LG443 gives you a reliable secondary aiming reference that lives on your gun full-time.
