I've often thought about enrolling in one of the classes taught by Rob Pincus. I just went over to the book case here in my den and counted 29 of his videos that I purchased through the NRA. They contain a lot of good information, especially for those who might be new to the world of personal defense and concealed carry. For those who have been through military, LEO, or other private training , they provide what might be described as a good "refresher course."
Of course, as useful as videos may be, they don't provide the same value as personal training.
