I took this class Friday from HGR Firearms here in Middle Tennessee. It's a great course. The NRA actually uses the phrase :If you look like food you will be eaten" in the video portion. We trained in defensive sight alignment, snap shots, double and triple taps. Shooting from strong and weak barricade, kneeling. All the fun stuff you can't really do on a range when you target shoot. We covered some of the physiological aspects of having to shoot at another human being. It's also a prerequisite for the NRA Personal Protection Outside the Home course that I want to take next.
If someone in your area is holding this class...I'd strongly consider taking it.
You can never have too much training.
