SureFire X400 Pistol Light

SureFire X400 LED / Laser Weaponlight

The SureFire X400 is a rugged LED WeaponLight with a powerful, fully integrated red laser sight. Its versatile beam and highly visible laser make it an excellent choice for both close- and longer-range applications. The X400’s solid-state LED, which has no filament to burn out or break from the effects of recoil, generates 110 lumens of blinding light and continues producing tactical-level light (enough to overwhelm the night-adapted vision of an aggressor) for 2.4 hours on a set of batteries.

The X400’s unique Total Internal Reflection (TIR) lens gathers virtually all of the LED’s light and forms a tightly focused beam that reaches far into the darkness but has enough surround beam to accommodate a user’s peripheral vision.

At 635 nanometers, the X400’s laser sight is one of the most powerful available to the general public. Its shorter wavelengths make it nearly twice as bright as the nearest competitor’s laser sight, which means it’s more visible to the human eye and easier to track at longer distances. The laser’s sighting adjustment uses Nylok® screws, which won’t “back out” or loosen from the effects of recoil, so the X400 rarely needs to be re-zeroed—even after extended use.

A tough, hard-anodized aerospace-grade aluminum body protect the X400’s electronics, and a tempered Pyrex® window covers its TIR lens and LED. O-ring seals and gaskets keep out dust, dirt, propellent residue, and moisture. Ambidextrous switching makes it easy to operate X400 with either hand, and remote switching for many weapons is available for precise control without altering your grip on the weapon.

The X400 slides onto most handguns with Universal Standard accessory rails and fits many guns without rails via a SureFire rail adapter. It can also be mounted on long guns sporting a Mil-Spec Picatinny rail.

Direct mounts to all rail-equipped Glocks and other rail-equipped handguns including Beretta, SIG, Springfield and Kimber.

Also accepts optional pressure-activated switch that extends under trigger guard.
