I'm a 5 year police officer with the majority of my time spent on nights. I didn't make it a year before I decided I needed a weapon mounted light for my Glock 22. I looked at the Glock light, Streamlight TLR series, Surefire X200 and the Surefire X300 (which had just come out). I did a ton of research and settled on the X300 and had the light for almost 3 years. I got out of LE and sold most of my nice toys, including the X300. Fast forward two and a half years (May 2013) and technology has made leaps and bounds in LED flashlights. I'm starting over again working nights on patrol and needed a tach light for my Glock 17, so I ordered my Surefire X300 Ultra. This light is leaps and bounds better than it's predecessor. I personally don't think it's "too bright", although I've seen that written a few times. At night, it will light up a pitch black yard on a house perimeter check or the inside of a vacant building. It's solid and as close to bulletproof as any light is going to be. It's very, very lightweight....honestly, I can just barely tell the difference in weight when the light is on there vs when it's not. 500 lumens is truly retina burning. For those who work days, you need a light as well. It's nice to have a free hand to open doors on a house or building search and we all know it's dark in there as well, even when it's daylight outside. You don't have to be a cop. This light is perfect as a home defense pistol, resting insid a quick access safe or on a nightstand. The whole purpose of having a light attached to your pistol is to have both hands there to support your pistol grip. If the SHTF and you need to crank rounds off, you're going to want that extra control of your pistol to recover from recoil and put more accurate rounds on target. It has adjustable Allen screws, and comes with the wrech in the package, to adjust the tightness in which it attaches to your weapon. I loosened my considerably so that it's easier to get off when I want to carry my G17 as a CCW in an IWB holster. When it's back on duty or on the shelf, it slides right back on the pistol and you hear an audible "click" to let you know it's securely attached to the weapon. Even with the screws loosened, it has zero movement and its rock solid. Bottom line: if you want the best light out there, this is it. I use mine as a tool to bring me home safe every night, so I want the best. Surefire X300 Ultra is the best IMO.

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.

Item was not as described. Received a counterfeit, imitation branded X300 flashlight. Several indications it is a counterfeit. Images: Left authentic X300a, Right Counterfeit X300a - Lighter weight - Text and Text paint different quality. - Battery latch protrudes past latch housing - LED emitter is different - Battery terminal contacts is missing Surefire branding. - Light body paint is lower quality, sprayed on. - QR code and FC marking are incorrect. - Missing 1000 lumen marking - light beam much weaker and bluer than authentic Hopefully this helps anyone who has received counterfeit products as well.
