The instructor who’s demonstrating straight up has some skills. Lack of modern technique doesn’t seem to be hindering him in the least. One hand instinctive shooting is a very useful skill. In force on force training the ability to shoot effectively in, shall I say “improvised stances”. Shooting over the shoulder as you’re running and screaming like a little girl…okay, maybe not so much over the shoulder, but one handed point shooting while on the move or literally diving for cover. I have practiced point shooting for years (but almost exclusively with revolvers), and in force on force training, that paid off. I was the king of the “lucky shot”, many times scoring on my attacker while retreating, by snapping off a quick pointed shot. I’m a dedicated advocate of the modern technique, but I believe the “complete” handgunner should spend time point shooting. Air guns, air soft, or low powered rounds such as CB caps in your .22 are great ways to practice this.
