I'm not saying I ever did that but I may have. Shhhh.So you don’t bring the dot to the target, just like bringing the front site to the target?
In real world we have to be ready to aim from cover, move to cover, run, hide, and scream like a girl. All the time while our adrenaline is making our muscles shake and twitch in controllably.
We also have to take into account present our weapon in unconventional manners hitting door frames, steering wheels, building corners and any other thing that may get in the way of our bodies and weapons. Hell even if you have drawn your weapon a thousand times there is a good possibility you will at best fumble the draw, or at worst drop it.
And do not say it will not happen to you, if so you are only fooling your self.
Adding anything to my personal carry weapon that could be damaged or compromised in such situations, is a no go IMO.
