Setting: Modern setting, fictional city
1. How long would it take to learn how to use a handgun? My character's an adult and not completely naive about them but he's never actually fired one before. He's quite perceptive and has good reflexes but I'm not really sure about the qualities that make someone good with a gun. I don't want him to be a perfect or even very good shot, just to be able to hit a target.
2. In your experience, what are the most difficult things about using a gun for the first time?
3. Lastly, he'd be learning from a colleague as opposed to learning from an instructor. Again, this person hasn't got perfect aim but he's quite good so how far would this effect him? If the person's not a bad teacher would it make any difference at all?
EDIT: Added Subject. Sorry, guys, I totally forgot.
