In about four hours' time, McDaniel could teach the average cop to draw and fire his carry gun deliberately and safely in about half a second, and regularly hit a beer can 21 feet away; and then continue pivoting and shooting to hit the rest of the cans in the row almost as fast as he could pull the trigger. Once he had learned the technique, the student could then fire all six rounds into the same can if he so desired. For plainclothesmen who requested it, McDaniel would analyze the motions required to draw the student's handgun from any particular type of concealment holster, and then work up a specific set of procedures for drawing the gun swiftly from it.
