Very pleased with the latest addition to my weapons capability with the Surefire X300U. I have it deployed on an FN 509 Tactical and the quick mount system is clean quick and rock-solid secure. It provides an amazing amount of light and a focused bright white beam that illuminates well over one hundred yard out. The tail switch is a rotating on-off switch with light touch end points easily controlled with a trigger finger for momentary on function when light pressure is applied. The aluminum light body and the rotating switch are stout well designed and thoughtfully executed.
I would certainly recommend, highly in fact, to anyone looking for a high quality weapon light with a powerful beam and excellent controls. I am tough on my weapons and weapon mounted hardware. They are in transit a lot and survive numerous bumps and bruising handling without failure or complaint. I buy the best because I know I can depend on the best, anything less is just that, less.
