This is a drill that I practice on a regular basis in order to develop and maintain the ability to hit the “GO” button and be proficient and accurate if I ever need to.
I’m performing this drill here at 5 yards.
There are two ways I practice this drill. One way is for cadence. I’ll fire the first 3 or 4 or 5 shots with a specific, fast cadence in mind, then follow up with the reload and face shot. The other way is what I’m demonstrating here: two controlled pairs followed by a reload and shot to the face.
The practical logic here is that I’m shooting to stop a threat with controlled pairs to the vital area of the chest. The gun runs dry and so I reload and, since the threat was not stopped by the previous shots, I follow up with one more to the occulonasal area of the face.
I run this drill at 5, 7 and 10 yards. It’s important to to get comfortable with the fast cadence and to work for accuracy in all of the shots. You have to learn to trust to your grip and fundamentals for speed shooting–and correct them when and if they fail you in a drill like this.
