The SureFire X400U is expertly designed to fit almost any pistol equipped with a rail system.
Its recoil-proof LED and TIR lens focus 1,000 lumens of light into a smooth, long-reaching hybrid beam, delivering a prominent central hotspot with generous peripheral spill – an ideal setup for both close and medium-range use. The X400U is available in a high-visibility green (<5 mW / 515 nm) laser, which is highly visible to the human eye, enabling rapid and precise target acquisition.
Constructed from high-strength, aerospace-grade aluminium and finished with a Mil-Spec hard-anodised coating, the X400U is lightweight, robust and weatherproof – more than capable of withstanding demanding conditions. O-ring and gasket seals provide extra weather resistance, while the unit mounts securely to both Universal and Picatinny accessory rails. The X400U also accepts optional pressure-activated DG and XT remote switches for enhanced control without compromising your grip.
Whether fitted to a pistol or long gun, the SureFire X400U is a clear statement of your commitment to security and reliability.
