SureFire X400 Ultra Tactical WeaponLight with Green Laser
SKU #: SF-X400U-A-GN
A high-performance LED generates 500 lumens of brilliant white light that is focused by a Total Internal Reflection (TIR) lens to produce a tight beam with extended reach and significant surround light for peripheral vision. The X400 Ultra produces tactical-level light—enough to overwhelm an aggressor's dark-adapted vision—for 1.5 hours per set of batteries.
The X400 Ultra’s 5-milliwatt laser sight, located below the primary light, emits a high-visibility green (505 nM) beam. 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.
Activating the X400 Ultra is done 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. A separate switch at the rear of the X400 Ultra allows you to (1) activate white light illumination only, (2) activate white light illumination simultaneously with the laser sight, (3) activate the laser sight only, or (4) disable the entire X400 Ultra. See illustration at upper left.
The versatile X400 Ultra can be attached to a pistol or a long gun since its Rail-Lock® system permits rapid attachment/detachment from either Universal or Picatinny rails. Its high-strength aerospace aluminum body is Mil-Spec hard anodized for superior toughness and corrosion resistance and is O-ring and gasket sealed to keep out dust and moisture.

SureFire X400 Ultra - Finally Pulled The Trigger
I have had my eye on the original X400 for years, and I finally decided to pull the trigger on this X400 Ultra with green laser. You can do your own research on green vs red laser. Based on the fact that this maybe the only handgun light I ever need, I decided to splurge and go with the green laser which is said to be brighter and easier on the eye than the red laser. I know many people may hesitate as I did as well and look at units that are half the price. But under extreme situations when you cannot afford to have your equipment fail, go with a reputable brand. You do get what you pay for and you do not want a "toy" on your gun.
ProsVery well built and extremely strong laser. I can even see the length of the beam in the dark.
ConsExpensive, but worth it!

Sure Fire X400 ultra 500 Lu./ Green Laser Designator
High Price, Yes. High Quality, You bet. Does everything it advertises, Yes. The only problem was a previously purchased D.G. Switch for a specific H.K. Pistol. The S.F. X400 does not mount as far back on the rail as a S.F. X300. I will have to contact Sure Fire to obtain a solution. I have every confidence in S.F.'s Customer Service to come up with the answer, from previous contacts. Would I recommend this product to a friend? Absolutely!

If we pre-order this product now and then Surefire decides to raise the retail price upon release (for some reason or another), are we guaranteed the current Sale Price or will the final purchase price be automatically adjusted to reflect any change in MSRP?
if you were to pre-order this item the price would be locked in at its current price when ordered.

Okay, it is past the end of January and early February, any genuine/accurate updates from SureFire, or is this item now permanently backordered (aka no chance of it ever being released)? 3 months from its official announcement is a bit odd for SureFire.
Unfortunately it appears that surefire has had some development problems with this weapon light and have not given a accurate release date yet as they have had to delay it again. gather that they are going to have an official release date "soon" as soon as we have access to this information we will be announcing it through our site.
