The second half of the posts above mirror my thoughts, training and IMO good common sense.
Only pull your gun if you are in a situation that warrants the use of it. Otherwise you could be in some big trouble (Menacing, Brandishing, Etc).
During any such encounter, you should be constantly evaluating the situation. You do not want to train yourself that a trigger pull is automatic after drawing.
Say someone turns and runs, or backs off with their hand up as they see you un-holster. Shooting them in the back, or after surrender in front of witnesses lands you in a world trouble in the form of homicide, or manslaughter.
Of course you must always be willing and able to pull the trigger if necessary, for the above mentioned reasons.
