My second question is, I doubt it will ever happen, but if I actually have to use my pistol, how would I be able to aim accurately? Most likely I'd have an adrenaline rush which would probably make my aim a little shaky, and the last thing I'd want to do is miss and possibly hurt someone else.
This is how I heard it:
"In the event you NEED your gun, you will not rise to the occasion, but will sink to the level of your training. Train accordingly."
You need to practice your presentation (draw and aim/draw and point, as the situation dictates) enough that it becomes a reflex-so you can do it without thinking..... the muscles just do the right thing out of sheer habit. I Carry a 1911 style pistol, and sweeping the safety off is so ingrained that when using a revolver at a bowling pin match, my thumb flicks the non-existant safety as i bring the gun up from the table ...... I "know" there's no safety there, but my thumb does not seem to care.....
