A defensive shooting drill intended to counter a failure to stop after two rounds to center of mass do not seem to stop the attacker, such as in the case that the attacker is wearing a protective vest or is under the influence of mind-altering chemicals. "The problem for the shooter is to change his pace, going just as fast as he can with his first pair, then, pausing to observe results or lack thereof, he must slow down and shoot precisely. This is not easy to do. The beginner tends to fire all three shots at the same speed, which is either too slow for the body shots or too fast for the head shot. This change of pace calls for concentration and coordination which can only be developed through practice." -- Jeff Cooper in Jeff Cooper's Commentaries

Setup:
Single silhouette target; distance based on shooter's skill level.

Procedure:
Start facing the target. On the signal, draw and fire two shots to center of mass and then one to the head. Score per appropriate sport rules, though there must be a head shot. Lack of a head shot is considered a miss.

Variations and Similar Drills:
Vary distance based on skill level.
