The Crimson Trace LTG-773 Lightguard is a trigger-guard-mounted weapon light built for Glock 42, 43, 43X, and 48 pistols. At 110 lumens, it delivers solid illumination for close-quarters situations—home defense, low-light shooting, or everyday carry scenarios where you need to see what you're aiming at. The polymer construction keeps weight minimal on your carry gun, and the matte black finish won't catch light or glare. If you run one of those compact Glocks and want reliable mounted illumination without complexity, this light bridges that gap.

Activation is ambidextrous and intuitive: dual-side controls let you engage the light with either hand, and you can toggle between momentary and constant modes depending on your needs. The light runs on two included 1/3N lithium batteries and delivers over an hour of runtime before a swap. The battery cap is designed for quick changes in the field—no tools, no fuss. For shooters who want their light integrated to the gun rather than mounted on a rail (most compact carry guns don't have rails anyway), the trigger-guard design makes this a practical fit.

Crimson Trace built its reputation on personal-protection optics, and this light reflects that focus: solid performance, user-installed, no unnecessary frills. It's the kind of gear that works when you need it and stays out of your way when you don't.
