The Mad Half Minute drill is the creation of Special Forces veteran Mike Pannone of CTT Solutions and is designed to test a shooter's ability to move, take an accurate shot and then move quickly again.
In addition to the usual, one spare magazine and a good pair of shoes with support. NRA bullseye target.
There are three firing points with the two outer positions being five yards from the center; target is 10 yards from the center position. On a start signal, the shooter has 30 seconds to fire the first round from the holster, move to one of the outer positions, plant and fire one round. Keeping the gun pointed downrange, the shooter then moves back to the center position, plants and fires one round before moving on to the other outer position. All that before time runs out.
A clean run on the Mad Half Minute is all 11 rounds in the black. A nine-ring hit is minus one point, an eight-ring hit minus two and so on.
As Pannone says, you can't fling rounds in order to get an accurate hit. You have to plant, assume a proper body position, align the sights and control the trigger. Hitting a black bullseye at 10 yards is a challenge just standing still, moving rapidly makes it much more difficult.
