Addressing the issue of the weapon light making YOU the target, it has been my experience that the X300 in the face kinda blinds folks.
I agree, just like Varmint said above, and thanks for the info Sam.
That's been my thinking, too, i.e., that a high intensity light to the face would be very disorienting. It's hard to look directly at it, let alone aim a gun at it.
As for it being a liability, my practice is to keep the trigger finger outside the trigger guard while working the light in search mode.
