X300 Ultra WeaponLight

Product fits PERFECTLY on my Beretta 92FS.

*** WARNING ***
Do NOT use the MR11 shim if you don't have a model 92F. Surefire has made this product to fit exactly on the 92FS without it, and if you try to use the shim provided, you risk having some real trouble removing the MR11 adapter mount.

Keep in mind that with a light attached, your holsters become useless. Identify a holster that will accommodate the modification, and take some time looking over the fit charts provided by various companies seeking such products. Purchase it first.

The light is extremely powerful, and simple to operate, ambidextrously. I will buy another one soon, for my other 92FS.

Nothing dramatic to report on the new weapon light. It's just like all the others. Precisely made, well designed, probably better than it needs to be. It more than lives up to expectations and I'm very pleased to have access to such a solid American company. Some are inclined to feel the price is too high. I think we're lucky to have these products available to us.

X300 Ultra

Easy to mount, blinding light, rugged, but still feel it is a little overpriced.

Product exceeded expectations; easy attachment/detachment to/from firearm, simple manipulation of on/off mechanism, push for momentary on allows trigger finger to remain indexed outside trigger, lumin output in side by side comparison with other products drastically outperforms others. Only negative found is that lumen output is so bright that when conducting room entries with white/light walls in smaller rooms, refelctive light off walls could hinder vision.

I have several Surefire mounted weapons light. This one is the most compact and brightes that I have. Ideal for pistol or long guns.

Unmatched quality

Love this x300 ultra. I received it in the mail quickly and got it on my Para Black Ops 1911 as fast as I opened the box. Very easy to turn on and off and also has a push mode where you can turn the light on quickly and then let off to shut the light off. Very bright and a lot easier to shine a massive amount of light on the subject without loosing the control of having two hands on the gun. Defiantly will be putting SureFire products on a number of my guns!

Brighter than the sun!

This new light is crystal clear and still has the versatility of there previous versions. Price point is about right only issue at the time of purchase was the holster options for a handgun mounted operation. Surefire does it again A+

Light is super bright. Works very well and does not drain the battery as fast as I expected. The only negative is that is a bit longer then the one I replaced which made it necessary for me to remove the cup from the end of the holster.

The powerful and versatile SureFire X300 Ultra WeaponLight for handguns and long guns features a high-performance LED that generates 500 lumens of stunning white light focused by a Total Internal Reflection (TIR) lens to produce a tight beam with extended reach and significant surround light for peripheral vision. The virtually indestructible and highly efficient LED generates tactical-level light—more than enough to overwhelm an aggressor's dark-adapted vision—for 1.5 hours per set of batteries.

Activating the X300 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. Optional DG grip switches (for pistols) and a pressure activated XT07 tape switch (for long guns) permit the X300 Ultra to be activated without altering your grip on your weapon.

The X300 Ultra can be attached to a pistol or a long gun since its Rail-Lock® system permits rapid attachment to and removal from either Universal or Picatinny rails. Its high-strength aerospace aluminum body is Mil-Spec hard anodized for superior toughness and is O-ring and gasket sealed to make it weatherproof.
