Color: Black
Style: Rail-Lock Mount
Pattern Name: WeaponLight
This is a very bright light that just feels and feels like solid quality. I have it mounted on a Glock 17 and it fits perfectly. Pros: Solid, quality construction Metal housing Lightweight Bright Easy to operate Easy to install/remove Balance It just feels like a solid light, and even looking at it in the package you could tell it would be a quality product. The aluminum body is strong and makes the whole unit lightweight. This light is very bright and is pretty easy to turn on with one finger. Momentary on is accomplished by pushing the switch forwards (towards the lens) and is easily accomplished with an outstretched finger without changing grip. Constant on requires spinning the switch clockwise OR counterclockwise. I was able to do this with the same single finger as momentary on. Using the lever lock, it's easy and quick to install and remove the light. Just pull down on the lever and slide it on/off. The other mounting method, the Rail-Lock, is also easy to install. The Rail-Lock is similar to the lever lock in that it locks into a rail slot but you need to use an allen wrench to tighten a sort of friction lock against the weapon. Both are very solid mounting options though. This light doesn't weigh much, 4 ounces according to SureFire, but it does help balance the weapon in hand. Cons: No light lockout Changing batteries requires removing the unit from the weapon No strobe Expensive There is no lockout on the light, so it is possible that the light could get turned on accidentally in a weapons case or bag. Changing the battery does require removal of the light from the weapon. On a pistol it would most likely be backed up to the trigger guard, and on a rifle the battery door opens towards the rail and thus cannot open far enough to remove the battery. If you install this light on a rail riser, you may be able to open the door without removing the unit. However, as I said above, it's very easy to install and remove the unit so this is not too much of a problem. This unit does not have strobe, it wasn't advertised to have it but some of the other light in this range to have that feature. It is an expensive light for just being a light. However, for the brightness and quality of the unit I would say it is justified. Recommendations: It's an excellent light. There are brighter ones, and cheaper ones. This is the first weapon light I have used, so I cannot compare to others. However, recognizing the quality in this unit I would definitely recommend this light to others looking for one.

Was worried that I would be buying a clone becausethe price was $100 less than everywhere else, but I got an authentic Surefire. It's bright, works and fits perfectly. Surefire sets the standard for quality and it lives up to the hype. I like the intuitive functioning of the switch press for momentary and up/down for constant, it's WAY better than Streamlight. You get what you pay for, love it so much I purchased a second one for my rifle.

Mount is very stiff adjust screws slightly. Came with Glock and 1911 rail mount. Get warm after prolonged use. Really bright light(blinding). Good front end weight. Won’t fit sub pistols.

This tactical "flashlight" is of excellent design and comes with extra pieces to allow it to be used both on a universal rail or a Picatinny rail. All you have to do is swap out some pieces with the spares they provide. As far as the light quality, I would say the light spread is tight and of a true circular pattern. It provides you with plenty of illumination to highlight the target but with enough ambient light to see at the sides as well. Is it 500 lumens? I don't know. I have no way to measure lumens but I can say that another of my Surefire flashlights seems to provide a brighter light and at a greater distance. That light is a E2D which is listed at 200 lumens. The only thing I can say is that the E2D is a bright white light and this light under review is a slight greenish light. Perhaps that would account for the perceived brightness I seem to see. Keep in mind that it is still plenty bright and will do the job intended without a hitch. So why did i give it 4 stars and not 5? Well first of all, 4 stars still donates a good value and high quality. But it receives 4 stars because you almost have to be drunk or high to pay $200.00 plus for a light. I was neither when I bought it, I used points. Lots of points. If you can afford it without points being used, have a couple cold ones and buy it, you'll like it.

Originally thought batteries were missing but they were inside the light! Light works great and is incredibly bright! Fits perfect on my glock19x and matches my OWB perfectly. Love the light, highly recommend!

The product was delivered on time and well packaged. And that was the only good part. For a brand name that is the industry standard I was extremely disappointed that it did not allow for an easy fitting or quick attach/detachment to ANY of my gear. I contacted the manufacturer who told me that “fitting is not guaranteed”. Other reviewers of this product listed the same issues and their resolution involved hand trimming the rail system. I believe the manufacturer addressed this issue with the B model but provided no solutions for the A model which is very disappointing because all it required was a replacement of the battery cap to allow for more fitting tolerance.
