Crimson Trace LG436 Laserguard Black w/Red Laser for Glock 19 Gen5/Gen3-4 Trigger Guard Mount (5mW 620-670nM)

The Crimson Trace LG436 Laserguard is a red laser sight designed for Glock 19 pistols across multiple generations, mounting directly to the trigger guard for a slim, unobstructive profile. Built for shooters who want a tactical aiming aid without modifying their slide or frame, this 5mW laser activates naturally when you assume your firing grip—no separate switch fumbling required in a moment that counts. It's ideal for defensive training, tactical practice, or low-light shooting scenarios where a visible aiming reference gives you a genuine edge.

The LG436 carries the hallmark Crimson Trace reputation for reliability in a compact package that plays well with standard holsters designed for subcompact Glocks. The trigger guard mount leaves your pistol's ergonomics and handling completely unchanged, and a master on/off switch lets you train with or without the laser depending on your drill. Whether you're running drills at the range, carrying for self-defense, or exploring tactical shooting techniques, this laser keeps your gun running exactly as the factory intended while adding a precision tool to your sight picture.

Factory sighted at 50 feet with a tight 0.5-inch dot diameter, the red laser (620–670 nanometer spectrum) is bright enough to use indoors and outdoors across typical defensive distances. The black anodized housing blends seamlessly with your pistol's finish, and the trigger guard platform means quick installation without permanent modification.
