This drill is focused on getting accurate hits on a small target, with the added challenge of clearing a malfunction as it occurs.
Target: any target with four 2-inch dots.
Distance/Time: 5 Yards / 15 seconds
Drill: Have a friend set up a 12 round magazine plus one dummy round. At the start signal, fire 1 round into each target freestyle (both hands on the gun). Transition to your strong hand and fire 1 round into each target. Finally transition to the support hand, and fire 1 round into each target. This drill is pass/fail. If you drop a shot off the target, it is a fail.
When you encounter the dummy round, you MUST clear the malfunction the same way you are shooting (strong hand only, both hands, etc.)
