I recently completed a CPL class. Shooting skills were practiced at a distance of 21 feet or less, most between 6 and 12 feet, point and shoot, on the move, even in the dark. No reloading practice drills, either. All you got was what your weapon could hold and try for center mass. No head shots, no warning shots, no wounding to make them think twice. One thing (amonst many others) was if you're in a darkened room and you fire your weapon, MOVE. If you missed, you've just staked out your opponents target.
