Okay as a start in gun handling.
Then it is not defensive training.
One step at a time my friend is the way I approach it. People have to build up to that high speed stuff. I see a lot of instructors and trainers skipping right over a lot of fundamentals. Not saying you are one of them.... but there is a lot of them out there. Lots of focusing on the tactics and not the individual. Negligent discharges from sloppy firearms handling happen all the time...even in LE circles. There is a fine line between defensive and offensive training when someone has little training and not great at controlling emotions under stress. Its that famous line ..."with great power comes great responsibility". That goes not only for the student but also the instructor/trainer. This is not golf or tennis nor is it basic training or police academy. Both of which deal with mental conditioning along with hands on firearms training. Some of these "experts" are going to end up in court with some of this razzle dazzle training.
