If you you have a rail, would you use a "flashlight" or a laser? In my thinking, it seems to me that a light illuminating the entire target area, i.e. the bad guy, would be better than a bead on a target I may or may not see all that well. Maybe I'm missing something about the laser thing, but for me it would be identify the threat as real (illumination) and then start shooting for center of mass. Thoughts?
