SureFire X400UHAGN Weapon Light with Green Laser - 1000 Lumens, Universal/Picatinny Mount, Black Anodized Aluminum

The SureFire X400UHAGN weapon light with green laser brings serious capability to any rail-equipped pistol. At 1,000 lumens, this tactical flashlight floods your target area with powerful white light while the integrated 5-milliwatt green laser gives you an aiming reference that's highly visible across varying distances. Whether you're training on the range, setting up a home-defense pistol, or running low-light drills, the X400UH combines illumination and targeting into one compact, recoil-proof unit mounted directly to your handgun's Picatinny or universal rail.

The engineering here is purpose-built for serious shooters. SureFire's hybrid beam pattern spreads light intelligently—a focused central spot reaches out to 213 meters, while generous spill illumination keeps your peripheral vision intact so you know what's happening around your target. That matters in low light. The ambidextrous momentary and constant-on switch lets you activate light, laser, or both instantly with either thumb, and the whole assembly attaches securely to both Universal and Picatinny rails without wobble. The Mil-Spec hard-anodized aluminum body is light, corrosion-resistant, and built to handle recoil without flinching.

If you run a SureFire MasterFire holster, the X400UH integrates directly—the cam-slotted bezel and rear locking lugs mate with the holster system, letting you set it to auto-activate the light and laser the moment you draw. That's seconds saved in a fight. Comes with two 123A batteries (enough for 1.25 hours of runtime) and accepts optional remote pressure switches if you want hands-off control without moving your grip.

Frequently Asked Questions

Will the X400UHAGN fit my pistol?

The X400UH mounts to both Universal and Picatinny tactical rails, so it works with any rail-equipped handgun. It's engineered to fit virtually any modern tactical pistol with a rail slot.

Does it work with SureFire MasterFire holsters?

Yes. The cam-slotted bezel and rear locking lugs on the X400UH battery housing interface directly with SureFire's MasterFire Rapid Deploy Holster system, allowing secure mounting and optional auto-activation of the light and laser when you draw.

Can I control the light and laser separately?

The integrated ambidextrous switch operates both the light and laser together. You can use momentary activation (press to activate) or constant-on mode (toggle to stay on). Optional remote pressure switches are available separately if you want alternative control without changing your grip.

What batteries does it use and how long will they last?

The X400UHAGN ships with two 123A batteries included. Runtime on a full charge is approximately 1.25 hours of continuous use.
