Surefire X400 Handgun Tactical Weaponlight w/ Laser Sight Product Info

The SureFire X400 Weapon Light w/ Laser Sight is part of the finest series of handgun weaponlights in the world.Period. These gun lights combine functionality, versatility, adaptability, and durability into a tiny, tough package that turns your pistol into a formidable weapon that rules the night. The Surefire X400 Flashlight features an electronically regulated, recoil-immune LED that generates 170 lumen of blinding white light and continues producing enough output to overwhelm an aggressor's night-adapted vision for nearly two and a half hours on a set of Surefire batteries. But these weaponlights aren't just about blinding bad guys. The versatile beam of the Surefire X-400 Gun Light is perfect for both close-quarter and longer-range engagements, with a tight hot spot that reaches far into the night. But it also provides enough surround beam to accommodate peripheral vision and avoid any sudden surprises, the cause of many accidental shootings.

With the addition of a cleanly integrated red laser sight below its LED, the Surefire X400 Rifle Light adds one more level of functionality. Its laser sight has a 5-milliwatt power output at 635 nanometers wavelength, making it nearly twice as visible to the human eye as any competitor's, so it is easier to track at longer distances. And because the sighting adjustment uses Nylok screws, which don't back out or easily loosen from the effects of recoil, the Surefire X400 Weapon Light rarely needs to be re-zeroed-even after extended use. Throw in details like a tempered Pyrex window; a hard-anodized aerospace-grade aluminum body; O-ring seals and gaskets for waterproofing; and ergonomic, ambidextrous switching (remote switching options also available), and it's easy to see why these lights are showing up on so many well-dressed weapons. Not just handguns, either - Surefire X400 weaponlights fit both Universal and Picatinny rails, so feel free to mount one on your Picatinny rail-equipped long gun, too. And with multiple SureFire adapter mounts available, which let you attach these Surefire weaponlights to many rail-less handguns, is there any reason your favorite pistol isn't equipped with a Surefire X400 Light? We thought not.

Helpful Negative Review too much trouble for the money by Legacy Reviewer, August 10, 2009
My first experience with Surefire. I bought one for a sig P229 9mm because it's the only light laser that uses an LED and offers a tailored grip switch. It stopped working (light and laser) after a few range trips. I shipped it back and received a...

Most Recent Review Surefire X400 Handgun Weaponlight w/ Laser Sight by Legacy Reviewer, September 13, 2013
I have a Sig Sauer P220. For some reason (could be my error), the laser is 3-4 ft. below where I normally aim (and hit) at 25 yds. I've tried with the U and P cross members. I've adjusted the elevation every which way. I'm sure the unit is mounted...

Most Recent Review Great attachment, price a little steep by Legacy Reviewer, September 23, 2012
this is a nice light attachment. The laser is bright that it could be used during the day. It's up in the higher price range, but I would not hesitate in buying another one. Pros: It works! Holds zero after several hundred rounds Cons: it's a little ...
