Get your lies right. That Colonel Jeff Cooper would ever back down to you is absurd. Your PIP, with a pistol. is an old and useless method of combating recoil. It has not been taught in thirty years. Stranger and stranger. And now he's got Jeff Cooper afraid of him. PIP was a stupid idea that you could combat the recoil of a pistol by pushing the pistol forward slightly before pulling the trigger. The real term for it was "missing". Get up to date!
