The X400 Ultra WeaponLight with Green Laser was created to interface with SureFire's revolutionary Masterfire Rapid Deploy Holster. It features a unique bezel with cam slots, and pin slots on both sides of the body, that lock the light into the holster, securing the weapon at an advantageous angle for quick deployment. It is also designed to automatically activate when the weapon is drawn from the holster. This model has a recoil-proof LED covered with a proprietary TIR lens that focuses 600 lumens of light into a smooth, farther-reaching beam with a large central spot. The 5 mW / 505 nm green laser sight is highly visible to the human eye and rarely needs re-zeroing.
