Shooting moving targets and/or distance takes some skill, shooting a non moving paper target at one foot does not. Presenting a firearm during hand to hand takes skill, but is unsafe to practice/train with a loaded firearm. Since no skill is needed to hit a still paper target at one foot, then one should practice presentation at hand to hand range, and if possible train with a certified sane, responsible trainer. That means seeking out MA instructors who specialize in firearm retention and hand to hand presentation with a firearm. And they for the most part do not even allow firearms in the classroom, let alone loaded ones.
Unless ISPA has changed their training was with rubber guns, and hand to hand instructors, that is the responsible way to train for such an event. Even if Pincus had not swept his hand, though he clearly did, my wife and I counted 4 times. It is this training(cough, cough) that HAS caused negligent discharges and injuries, and Pincus knows it. He is trying to make a buck, he gets interest in his classes where he can make more money, plus for every click on his youtube account he is paid for the advertising that is imbedded in his videos.
He really doesn't care if you shoot yourself, just making money. That is the problem with the CC industry right now, it is all about making money and screw it if anyone gets hurt.
As a disclaimer I make no money from recommending responsible MA trainers. I am not a MA trainer, and belong to no MA interest groups or clubs. I am not even a member on any MA websites.
You do not have to become a black belt to learn proper technique. Take a few classes, learn, and then you can practice on your own. You can learn by video but it is not the same and more chance for injury if not overseen and done right.
