I've been wanting to take a good force on force class but have not had luck finding one near PA (PA, OH, VA, WV). The only one I can find is "The Fight" at Tac Response in TN. I am curious to know what are some changes to your training as a result of taking a FoF class? Have you added more 1-hand shooting drills? 1-hand reload drills? More shooting on the move inside 10yards? Drills where you seek cover instead of engaging in the open? What have you stopped training?
