This drill supposes you’re running away from an armed assailant, then a second cuts you off and you must defend.
Draw from concealment and put 2 rounds on the 8″ plate at 10 yards, you run empty so perform a reload and put 1 round on the other bad guy while advancing on him (intimidation factor works on most folks, causing panic or surrender or sloppiness).
I did this drill about 20 times today. This run was toward the end. Good workout!
