Dear Jim: Yes, it does apply to semi autos. The techniques for defensive use of the pistol defined by Jeff Cooper call for two quick shots per target as a form of insurance. The classic standard exercise is to place 3 silhouette targets 1 meter apart, 10 meters down range. Starting with a loaded pistol in the holster, the shooter draws and fires two quick shots at each of the 3 targets, then reloads, then repeats.
