Draw With Maximum Efficiency. If your pistol is equipped with a SureFire X400UH, you have a clear advantage. The X400UH is engineered to fit virtually any rail-equipped pistol and interface with SureFire’s revolutionary MasterFire® Rapid Deploy Holster. It locks securely into the MasterFire, securing the weapon at an advantageous angle for quick deployment and can be set to automatically activate the light and the laser when the weapon is drawn, saving critical time in a crisis situation. Its recoil-proof LED and TIR lens focus 1,000 lumens of light into a smooth, far-reaching hybrid beam with a large central spot and ample spill for situational awareness. Available in traditional red (635 nanometers) or high-vis green (515 nanometers), its 5-milliwatt laser is highly visible to the human eye. With a Mil-Spec hard-anodized aluminum body that’s light, strong and weatherproof, the X400UH will get the point across to any opponent.
