The SureFire X400U is designed to fit almost any rail-equipped pistol. Its recoil-proof LED and TIR lens channel 1,000 lumens of light into a smooth, long-reaching hybrid beam with a large central spot and ample spill light, providing an effective mix 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, helping the user get on target quickly and accurately. With a Mil-Spec hard-anodized aluminum body that's lightweight, durable, and weatherproof, it can withstand tough conditions and remain operational. Mounting an X400U on your pistol or long gun clearly shows that you take your security seriously.
