You can be the best target shooter in the world but if you can't fight HAND-TO-HAND at CLOSE RANGE you will never even GET to your gun. Worse, you could be shot with your own weapon! And if you get the microsecond to draw, traditional Isosceles or Weaver stances could get you killed. Reactive self-defense with a concealed carry handgun is a very different dynamic from the proactive military/police tactical team scenario that much modern firearms training is based on.
