Just a thought: You can not make the dot appear. It has to appear on its own. There are many things you can try but this will be the simplest.... Get into your stance adn drw with your eyes closed. After you are at full draw and settled, open your eyes and see where the dot is. If you can see it without moving the gun, you are 99% there. If you can't see it, figure out where the dot is without moving your wrists. Moving your wrists will alter your grip and cause more problems.
Move at the waist, knees and very slightly at the shoulders (do not move your head). Once the dot is in the center of the glass, close your eyes for a couple of seconds. When you open them it should still be there. If it is not, readjust and try again. If it is, close your eyes again and pull the gun back toward your body. Push it back out to "full extension" and open your eyes after everything has settled. If the dot is there, you are very well on your way, if it is not, try again.
What you are doing is trying to isolate specific body motions and refine them. I agree that we need to see what is going on, but with our eyes being the fastest muscle, then tend to see inprofections as they occur and direct the changes as necessary. If you can teach yourself to present the gun with the right form, when the eye sees that the dot will be off, it will be a much cleaner, smoother, therefore fore faster "dot find".
I hope this helps!!!
