The Half & Half is an easy to administer assessment of speed and marksmanship. There are three strings of fire. With each subsequent string, you reduce the distance and the par time by half. The “official” version of the drill is dumbed down from the original carbine drill and is shot from the ready position:

1. 10 rounds at 20 yards, 12 second PAR time
2. 10 rounds at 10 yards, 6 second PAR time
3. 10 rounds at 5 yards, 3 second PAR time All shots must be fired before the end of the PAR time; shots fired after the PAR count as misses.

For a significantly better challenge, the “pistol-training.com version” of the Half & Half is run using the original carbine times, and also fired from either concealment or a retention holster:

1. 10 rounds at 20 yards, 10 second PAR time
2. 10 rounds at 10 yards, 5 second PAR time
3. 10 rounds at 5 yards, 2.5 second PAR time

Hits inside the scoring zone are 10 points each. Misses, shots fired after the PAR time, or unfired shots score zero. Maximum possible score is 300.
