I was looking for a good weapon light to accompany my EDC, a Gen3 Glock 19. I recently realized the need for an accessory light on a handgun, so I began searching for the best one I could afford. After looking at the streamlight and surefire models, I found a great deal on the X300U-A-TN. It's the tan version of the black bodied X300. The light feels sturdy and looks like it will handle the stress of lots of shock vibration and heat generated by firing thousands of rounds. The body is aluminum and the finish is clean and sharp. The light is very bright with a strong center illumination and soft peripheral illumination. It may actually be too bright in a dark home or close quarters areas, even when there is ambient light. These two images are roughly five yards distance from a plain wall in my living room during the day with blinds drawn. The wall is painted a tan/gray color that is more like a dark off white. There is obviously no "doughnut of death" as created with the maglights. I mounted this light on my G19 first, to get a quick feel of the switch movements. The continuous on/off actions are tight and slightly difficult to move with a single index finger. This may loosen up and improve with regular use and wear, but so far, I think it's too tight. The momentary on/off works well, and forces the user to practice good trigger discipline by keeping the trigger finger straight to actuate the switch. Again, however, I feel it is a little too stiff, and if used during a night course, would cause significant discomfort over a few dozen exercises. Again, this may improve with use. I found the switch to be a little too pointed which increases the level of discomfort. If used with gloves, these issues do disappear. My issue with it comes due to me using it as an EDC, and few people walk around wearing shooting gloves everywhere they go. The size of the light is fairly large, in my opinion. That is unavoidable, simply because of the size of the batteries needed to power its 500 lumens LED. This first image is the G19 I plan on having it mounted to. I foresee major issues with how I carry. I prefer appendix IWB carry, which has thus far been borderline uncomfortable, due to the tip of the barrel stabbing my inner thigh when seated. The added length will not help that at all. The entire LED and reflector housing protrude from the end of the muzzle. I then mounted it on my Gen3 G17 for reference... ...which is slightly better, but still protruding a bit. Finally, I mounted it to my Gen4 G41, which should give a good idea how it would be on a 34/35. Much better fit. I also noted that the added weight on the front of the gun will likely help with felt recoil when shooting. This is of course, subjective and I will update after I have sent a few rounds down the pipes. All in all, I am so far pleased with the light, but it does have several downfalls that I perceive may be an issue for me. It may end up staying on my nightstand gun until I can find a smaller light for EDC. I would recommend this light of for everyday DUTY use as gloves will likely make it easier and more comfortable to operate.
