I was watching this video and I was interested in the training concept, of using existing training with modification to implement training with modern weapons. In this case concealed carry (obviously more for countries that allow concealed carry, and likely more beneficially for armed police). I liked the narration on the video to show the thought process in training this way. I expect the common one is knife attacks, with the perpetrator using a knife. Has anyone done training like this with weapons that they could legally carry or use in their country?
