Love your logic this sounds like great tactics for EDCI don't mount anything on a handgun. I prefer it lightweight, balanced, compact and not bulky.
Better to carry a flashlight in your other hand, and position it away from your body.
I also never use a laser on a handgun, since it will lead an opponent's aim right back at you if there is particulate or smoke in the air.
Instead, train and learn instinctive point shooting.
