Surefire® X400 Ultra 1000 Lu Configurable Rail Handgun Light/Red Laser Sight


Pinpoint The Threat. The SureFire X400U is engineered to fit virtually any rail-equipped pistol. 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 plenty of spill light, an extremely effective combination for close- to medium-range engagements. Available in traditional red (635 nanometers) or high-vis green (515 nanometers), its 5-milliwatt laser is highly visible to the human eye to help the user get on target quickly and accurately. With a Mil-Spec hard-anodized aluminum body that’s light, strong and weatherproof, it can handle hard knocks and stay in the fight. Mounting an X400U on your pistol or long gun is a clear sign that you take your security seriously.
