Layers of complexity, performance value and defensive utility.

Adding layers of complexity to drills you may already practice regularly can prove to be deceptively demanding. Bill drills are a great hard skill test of vision, grip and recoil management. Add a layer of complexity like movement and you have a Retreating Bill. This adds performance value and defensive utility. There are countless videos showing real world defensive use with a pistol that mirror this drill. Adding movement takes you out of the static prepped position and makes the vision, grip and recoil management pieces more challenging. As you progress you can begin to introduce more layers of complexity like 90°/180° turns, different hand positions with eyes off target, forward movement then retreating and some realism like single hand draws carrying a baby. This will greatly improve the level of performance in your skill set while holding significant defensive utility.
