Jerry Miculek, fastest revolver shooting in the world, USES THE FRONT SIGHT. (per his CD, Ultimate Advanced Revolver).
He dosnt point, he uses the front sight. It dosnt appear to slow him down.
You spend hours, weeks, and years, getting on the front sight, and the time comes, In "panic must shoot situation", YOU'RE GONNA GET ON THE FRONT SIGHT, wheather you realize it or not. AND YOU'RE GONNA BE BETTER THEN IF YOU POINT SHOOT.
That is the whole purpose of Training, and Practice, to develope (GOOD) habits that your sub-consicence is gonna revert to.
Even as a LE firearms instructor, we had to qualify like everyone else (though we had higher standards to keep our instructor status). Even at 7 ft. I used the sights where the Chief Instructor keep scream POINT SHOOT, POINT SHOOT, I said why, I was well with in the time limit, and I had the groups to show the Fundamentals worked.
There no subsitute for training, using established fundamentals.
