The X400 Ultra (Green) is a compact WeaponLight for pistols and long guns featuring an ultra-high-output white-light LED and a green laser sight that’s optimized for human eyesight. Its recoil-proof LED and special TIR lens create a versatile, 1000-lumen tactical beam with extended reach, enough surround light to accommodate peripheral vision, and more than enough output to temporarily overwhelm the dark-adapted vision of an aggressor. X400 Ultra’s 5-milliwatt green laser sight is highly visible and, once zeroed, rarely needs re-zeroing thanks to Nylok® adjustment screws that won’t back out from the effects of recoil. The WeaponLight securely and rapidly attaches to either Universal rails on handguns or Picatinny rails on handguns and long guns. Ambidextrous push/toggle switching on the rear of the light provide one-finger control for momentary- or constant-on operation; optional DG grip switches (for pistols) and pressure-pad tape switches (for long guns) permit activation of the light without altering your grip on the weapon. Constructed of aerospace aluminum, hard anodized with a Mil-Spec finish, and O-ring and gasket sealed to keep out the elements, the X400 Ultra is a lethal combination of performance and durability for pistols and long guns alike.

Features
  • Special high-performance LED produces 1000 lumens
  • Custom TIR lens creates smooth, far-reaching light with a larger center spot beam
  • < 5mW / 515nm Green laser sight is highly visible to the human eye and rarely needs re-zeroing
  • Integral ambidextrous momentary- and constant-on switching

  • High-strength aerospace aluminum body, Mil-Spec hard anodized for extreme durability

Quite the Upgrade

I decided to upgrade my Glock. Yes, this was a very expensive upgrade but I love it. I'm colorblind so my cones don't pick up the red hue very well. I realize that red is better for concealment purposes but I'm a paramedic, not a military man. I love the green because of how bright it is. Yes, it's quite a bit more but I'm okay with that.

I have this fitted on my Glock 17 G4 with a Bravo Concealment holster and boy does this thing look GOOD! The selector switch is super easy to use. I found myself having to turn the gun upside down in order to remember what switch selection was what. You'd be amazed how fantastic the light with laser picks up on various surfaces. I thought the laser would be washed out by the amount of light but nope. The batteries last very long and I've never once had an issue. Good job, SF.

Superb light, but steep price

I've been a die hard Surefire fan for as long as I can remember. I have over a dozen of their handheld lights, but I have always had at least one dedicated weapon light for my home defense pistol. I recently purchased this light for my wife's pistol because she insisted on a green light, instead of the red version which I use for my bedside pistol, an HK P30 long slide.

We mounted this to my wife's pistol and it has already seen extensive use. We hit the range every week, so this light has been punished by a LOT of recoil and hasn't had any problems.

There are only two complaints with this light. First, SF customer service is simply not what it used to be. I say that because I have had a number of instances where I've needed to get some customer service, and for the amount of money these devices cost, I feel like they are not nearly as attentive as they were ten or so years ago when I first became a customer.

The second issue, specific to this item, is the cost. The green version of this light is 200 dollars more than the red, and offers no additional features of any kind. I'm certainly not an engineer, so it may be that there are additional challenges with creating a bright lazer that is green instead of red, so there may be some technical challenges that add to the cost of the light. But the additional 200 bucks seems pretty steep to me. That aside, this light is exceptional and won't let you down.

I have the red version on my home defense pistol, as well as a shotgun. You can't go wrong with this purchase if you can stomach the extra cost.

Latch Issue and Incorrect Lumens

I just purchased this item this week and the item I received has an output of 500 lumens as opposed to the 600 lumens advertised here. Also, I have an issue where the latch to pop open the battery compartment does not work properly. I can use a flat head screwdriver to depress the latch further to pop it open, so no real issue there. It just took a while for me to figure it out.

Best Product Made

I held off in buying this one at first. Don't believe all the internet ninja's! Too expensive....Too blueish of a light.....Red is just as good....Etc. Nothing could be further from the truth. This is the best laser/light combo ever made! Period! Perfect beam! Perfect bright green laser! Perfect mounting! No issues what so ever! I think a lot of the negative comments come from those who can not afford or are not willing to spend the $$$. My life is worth every penny for this light! This is the best product ever to come out of Surefire!

Owner/Defender

One of the staff members (a kid) at my local shooting range/gun shop became very intent and insistent on diverting me to a different model of this product when I asked them to order one of these for me. He tried to tell me that most of these were DOA right out of the box, claiming to have ex-military experience with SureFire products, and then told me that nobody uses a laser sight on a pistol anyway, and that I didn't need a light anyway with night sights on my P226. I politely told them to forget it for now, that I would re-check my research and return if I found anything different from my initial reviews of same. When I returned home, I promptly ordered one online, got it the next day, and found it to be flawless and in perfect working order. I found the light to be easily capable of lighting up an entire 22 x 16 residential room, and found the laser to be pre-zeroed for 7 feet, the distance I'm told by my local LE people at which most gunfights occur. I re-zeroed the laser for 7 yards, which is my standard practice distance from a target. This thing works perfectly, and is a great asset to this user and his aging, cataract-diseased eyes. Thanks for a great product.

Great Product

SureFire outdid themselves for sure on this product. I upgraded from the X300 to X400 for my G22, and wished I had done this sooner. The install was effortless, zeroing in the laser, simple, by far a superior light/laser combo. GREAT JOB SF!

High quality product

I don't mind paying more for the very best. The X400 with the green laser is very high quality inside and out.

Surefire also has very good customer support!

Great job!

Get Real

For one, very hard to find; called all my local shops and found one after 2 days of searching "in the DFW area". Would be easier to order one here. Installed this unit on my Sig p226 Mk25, got to say very pleased. Install of course fast and easy, sighting to zero a snap. The flashlight blinding even if you close your eyes. All in all extremely happy and plan on ordering another one for my wife's rig.
