SureFire has released two new models as part of its X-Series family of WeaponLights designed for handguns but can also be mounted to long guns with Picatinny rails.

The X300V and X400V IRc feature SureFire’s  V-Series head, a sealed, selectable head that contains both a white-light and infrared LED inside, to accommodate missions requiring visible and virtually non-visible (to the naked eye) illumination. By simply pushing and rotating a self-locking selector switch on the head, a user can switch from white-light to IR illumination (for use with night vision devices) on the fly, with no infrared filter required. The X400 model even boasts an infrared laser.

The X300V generates 150 lumens of blinding, tactical-level light on its white-light setting and 120 mW of infrared illumination when set to IR mode. Light output from either mode is shaped by a proprietary optic—a Total Internal Reflection (TIR) lens—into a high-intensity beam with significant reach and sufficient peripheral illumination for maintaining situational awareness, crucial in military, law enforcement, and home-defense applications.    

The X400V IRc generates the same high-intensity beam at identical outputs in white light and infrared as the X300V, but it also features a commercially available <0.7 mW infrared laser sight, suitable for force-on-force training and ideal for stealth operations using night vision devices. As with all laser-equipped SureFire X400 WeaponLights, the X400V IRc’s laser-adjustment mechanism uses Nylok screws that won’t back out from the effects of recoil. And because the IR laser is not visible to the naked eye, an amber-colored LED indicator illuminates whenever the laser is on, to help prevent unintended activation.

Like all X-Series WeaponLights, these new models are constructed of lightweight aerospace aluminum that’s hard anodized with a Mil-Spec finish and are O-ring and gasket sealed for added durability and weather resistance. The X300V weighs in at less than four ounces—including the weight of the two 123A lithium batteries that power it—while the X400V model is just under five ounces fully loaded, so neither model weighs down a weapon. One-finger activation is achieved via a push/toggle switch located on the rear of both lights; optional DG pistol grip and long-gun remote tape switching is also available. Both models attach quickly and securely to both Universal and MIL-STD-1913 (Picatinny) rails, and optional SureFire adapter mounts are available for several popular rail-less handgun makes and models.

The X300V has an MSRP of $389, while the X400V IRc retails for $875. They are currently available for purchase through authorized SureFire dealers and will soon be available direct from SureFire .
