Well this discussion came up at work yesterday and I was shocked to hear a few cops repeat the aspect of "its going to make you a target".

It only took a few minutes of some force on force with airsoft and it was pretty quickly settled on backlight being pretty much identical regardless of where the weapon it. It is simply rare that a room is so dark your curtain of light is going to totally conceal you. Then we went into the tunnel and there was no question how much better the accuracy and rate of fire was using a weapon mounted light. After all we carry guns and point them at people because we might need to shoot them right??

Hunt hard, kill clean, waste nothing and offer no apologies.
