In theory one can make your argument in a military combat type scenario. However, even then, the heat of the battle is going to be seriously distracting any opponent. The notion that someone will in all that confusion be able to exploit your laser beam, is a bit far fetched.
I'm not fighting bad guys in Iraq, though. For domestic personal protection use here in the USA, your argument is totally irrelevant.
I've been shooting handguns for 40 years now. My family is renown for its pistol shooting abilities.
If you don't want to take advantage of new technology that is now available, that is your choice.

LOL
I` made my choice long ago.
It has nothing to do with military scenario.
In your home ,during the night, with no time for lights....you pop that puppy off and you have just made yourself a target with a neon arrow pointing to you.
Was in a big farm supply warehouse one morning around 3:00 A.M. after a thief at a job I used to do.
I knew the cat was in there because I heard him from the outside before entering. The main warehouse light master switch was in the adjoining building. Dark as a whale`s belly, but I knew the layout real well. I was in there usually 5 to 6 times a night.
A friend of mine had stopped by to have coffee with me on his way home from work.
He grabbed his 9mm with all the bells and whistles and went in with me.
I was on one side of an aisle and he was on the other. Pretty tight place. Just wide enough fro a forklift to get through.
The moron who had broke in ran into something and made a noise. My friend activated his laser sight and swept the general direction. Lots of nice new shiny stuff in there. It looked like a Kiss concert or a laser light show.

All roads led to......the holder.
I told him if he lit that thing up again I was going to insert it in a place darker than where we were at the time.
When I found and got the burglar, he was even laughing his butt off about it. He even told my bud that if he had been armed and had wanted to it would have been too easy to take him out.
I`ve shot a year or 50+ myself.

If you feel the need to use <cough> modern technology...........feel free to do so.
