I want to read some discussion on pistol lights. I have been back and forth on this and need some feedback. At the root, they are designed to provide light to the target. while there are many brands, they all do the same thing. Obviously one wouldn't carry with one of these, home defense is in mind. Bedside arm is a Glock22 and Maglite. I want (not sure I need) a pistol mounted light to free a hand. Bright? Yes! they are. Cool and fun?sure. But what your thoughts on them? i am not usually in a tactical situation so what do you think about them? Thanks!!
