SureFire Introduces New 1,000-Lumen X400U & X400UH

Fountain Valley, CA-( SureFire, LLC, manufacturer of the world’s finest—and most innovative—illumination tools and tactical products, is proud to announce the launch of the all-new 1,000 lumen X400U and X400UH models. These will be available in the both red and green laser versions for holster compatible and non-holster compatible lights. The SureFire X400U is the finest duty-grade handgun WeaponLight and laser combination available today.

The X400U, features 1,000 lumens of stunning white light focused by a Total Internal Reflection (TIR) lens to produce a tight beam with extended reach and significant surround light for peripheral vision. Located below the primary light, the X400U’s 5-milliwatt laser sight emits a high-visibility beam, perfect for non-standard shooting positions and use in low-light scenarios. The laser’s aiming 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 X400U is activated via ambidextrous switching located at the rear of body, providing one-finger control — press the switch on either side for momentary-on activation, flip up or down for constant-on activation. Optional DG grip switches (for handguns) permit the X300U to be activated with one hand, without altering your grip on your weapon.

Price is a factor. 800 bucks is not justifiable when there are many other viable options for far less. The laser is a very useful tool. If you train to use the laser as an additional tool there are times in low light, particularly with iron sights when the laser makes the snap shot faster and more accurate. Room clearing in the dark, a momentary contact switch for laser and flashlight are very useful, especially if your light is set for strobe. You can see, identify, and target faster than your assailant. The laser should not be a crutch but,… Read more »


“Hey, Honey. I just bought an $800 flashlight for my new $600 pistol, and….”. I just don’t see this going down well at my house. However, if y’all were wondering what to get me for Christmas——

Anyone who says “laser is useless” must have young eyes (no presbyopia) and/or has never used a weapon-mounted laser.

That said, $800 is way too rich for me.


To E6H: Unbelievable, I purposely put the price here for all to see and what do you do? You ask the price! READ!

There, I fixed it for you.


Great light but laser is useless. What’s the cost?


And before someone asks I’ll give you the all important answer: $799.00 and it appears, right now anyway, that it’s only available from SureFire.
