Get what you pay for - SureFire X300 Ultra LED Weapon Light

This is one of those cases where if you want something you never need to worry about, just go with the Sure thing (pun semi intended). Mounted easy to my Sig p226R, and has had no trouble since. I will say, there is a slight wiggle to the light, that you dont get with the more permanent mount. Though, realistically, it is not that big a deal. I have already purchased another light of theirs for my USP 45 and will likely get others in the future.
