  • The SureFire X400 combines a brilliant white light with a bright red laser aiming device in one WeaponLight. A high-efficiency LED generates 170 lumens of brilliant white light focused by a Total Internal Reflection (TIR) lens to produce a tight beam with good reach and significant surround light for peripheral vision. The LED has no filament to burn out or break and generates tactical-level light—enough to overwhelm an aggressor's night-adapted vision—for 2.4 hours per set of batteries. The 5-milliwatt, 635 nanometer laser sight, located below the primary light, is nearly twice as bright and much more visible than the nearest competitor. The laser's adjustment mechanism uses Nylok® screws that won't back out from the effects of recoil, which means it rarely needs to be re-zeroed. The white light/laser combination makes the X400 effective in close- to medium-range engagements, ideal for law enforcement, military, and self-defense use. The high-strength aerospace aluminum body is Mil-Spec hard anodized for superior toughness and corrosion resistance, and is O-ring and gasket sealed to make it weatherproof. The X400 comes with two adapter wedges permitting rapid attachment to and removal from either Universal or Picatinny rails. An ambidextrous push/toggle switch provides one-finger operation for either momentary or constant-on operation, and a mode switch allows you to select white light only, white light + laser, laser only, or system disable

  • 5 out of 5 I couldn't decide what I liked more, the TLR-2 from Streamlight or this Surefire X400. I got both and compared them side by side. Both great products but I like this one more for a couple reasons.

  • 5 out of 5 They should call it the Surefire "SuperPro" X400! Both light and laser are Super Bright. Easy to install and easy to sight in. In this case you get what you pay for.

About SureFire

SureFire collage The tale of SureFire can be traced back to 1969, when Dr. John Matthews established the Newport Corporation. Dedicated to harnessing laser power for industrial uses, the company soon grew to be a leader in the field. After much success, Matthews turned his attention to his hobby of shooting and developed the first laser sight, which would lead to the founding of Laser Products. It quickly grew after loaning the L.A. SWAT Team laser-sighted shotguns for security at the 1984 Olympic Games. Years of working with law enforcement agencies led to the first SureFire weapon-mounted flashlight. Armed with this advantage, tactical and military operations have never been the same.
