A good practice drill is the El Presidente
Range: 10yd
Target: three IPSC targets spaced 1yd from each other shoulder to shoulder
Start position: back to targets, hands above shoulders (“surrender position”), pistol concealed
Rounds fired: 12
At the start signal, turn, then draw and fire two rounds at each of the three targets. Perform a reload, then fire two rounds at each target again. There should be four hits on each target for a total of twelve.
The classic standard was to perform the drill in under ten seconds with all A-zone hits. Any run with less than 12 A-zone hits was a failure.
Do it in 10 seconds with a carry gun and you are getting there...
