The gunfighter’s stance and drawing your gun from your holster was a popular depiction in western movies and televisioln shows.
The classic style was standing with your gun hand near your holster but slightly away from your body and reaching for your gun, drawing from the holster and then firing upon your enemy.
The “Border Style” gun draw consisted of pulling your pistol, worn backward in the holster, by putting your arm across the front of your body. This fancy stuff was popular down around the Mexican border.
It should be noted that this kind of quick-draw shooting did not exactly allow for accurate aiming when firing.
