Welcome to the forum. If you are planning to carry a weapon [concealed or not] for self defense, practice your intention. One very good way to do this after you get comfortable with range firing is to get involved in your local IDPA group. You can imagine what it is like to draw and fire in self defense. I believe it is actually better to do it a lot of times so you don't act like Don Corleone's idiot son trying to respond to an assassination.
