In this lesson, the instructor reveals one of the foundational accuracy drills — the Control-Pair. You will learn why this seemingly simple exercise is one of the most effective tools for developing stability, rapid sight recovery, and accuracy in controlled shot groups. The instructor explains the difference between series and groups of shots: — a series uses one sight picture for multiple shots; — a group requires re-aiming before each shot. You will learn why the Control-Pair belongs to group shooting and how it tests your ability to bring the weapon back onto target in under two seconds after the first shot.
