he down side of the light mounted on your weapon is (as a civilian), a) when you look at something with the light, you are pointing a (loaded?!) weapon at them, something which is generally not considered a friendly act.
And b) anyone who does shoot at you will have a strong tendency to shoot at the light.
Not being a hi speed low drag operator, my light will be in my off hand, held as well away from the rest of me as circumstances permit.
The place for the light is whereever you don't mind being blown to heck when the BG fires at the light. Of course if your head is behind the light, you won't mind much of anything. Ever.
I've seen it done but way not just mount it on the gun and shoot with two hands.
What you're describing is a scenario where you have your muzzle covering something you haven't identified and cannot identify without a flashlight. And that's something you're planning for?You have a fundamental misunderstanding of how to use the light. It's not for searching. Walking around with the light on would be stupid. It's used with a momentary switch for target identification when aiming, and only if necessary.
