The SureFire X400UAGN is a 1000 lumen weapon light with integrated green laser, built for shooters who need serious illumination and target-acquisition speed on a pistol or carbine. It mounts directly to Picatinny, Weaver, and Glock-pattern rails—making it at home on modern polymer pistols, AR platforms, and tactical shotguns alike. The combination of a bright, hybrid beam and a highly visible 5mW green laser gives you two ways to locate and engage a target, whether you're clearing a room, training at night, or working in low light on the range.

The optical system delivers 1,000 lumens through a TIR (total internal reflection) lens, producing a smooth beam with a strong central spot and useful spill light for close- to medium-distance shooting. That hybrid pattern is purpose-built for the chaos of real-world defensive scenarios—you get reach without sacrificing situational awareness at arm's length. The green laser (515 nanometers) cuts through daylight and darkness more naturally to the human eye than red, and it pairs intuitively with the flashlight for fast target confirmation.

Built from Mil-Spec hard-anodized aluminum, the X400UAGN resists corrosion, recoil, and rough handling. Ambidextrous momentary and constant-on switching lets you use it intuitively from either side of your grip, and the light accepts optional remote pressure switches (SureFire DG and XT models) if you want to run it off a rail panel or handguard. It's the kind of compact, feature-rich light that pairs well with serious training or a serious pistol.
