Designed to be compatible with the innovative MASTERFIRE Rapid Deploy Holster, the Surefire X400UH-A-RD Ultra LED Weaponlight with Red Aiming Laser has a specially engineered bezel and body that lock the light into the holster at a comfortable natural angle for a fast and easy draw. The holster system features a selector switch that can automatically turn the light on as the weapon is drawn, saving valuable time in high-stress situations. For ease of use, the light is automatically turned off when put back in its holster, but provides you with the ability to disable the automatic function if the situation requires it.

The light combines a 1000-lumen single-output LED light with a 635nm Class IIIa red aiming laser and can be mounted on pistols and rifles with Picatinny/Weaver rails. It features a Total Internal Reflection (TIR) lens that produces a pre-focused beam with a tight center cone of bright light, and a dimmer ring on the periphery to help maintain situational awareness. An ambidextrous toggle switch controls the momentary and constant-on modes and is easily accessible for your support hand to keep a firm and secure grip on your weapon. Designed for durability, this system features a weatherproof O-ring and gasket-sealed milspec anodized aluminum housing.
