Again we are NOT talking target accuracy. 10 feet is about average. Keeping this in mind, it is interesting to note when I went through the police academy that the majority of our shooting was beyond 21 feet. That is indeed strange. We haven't accepted the fact that dangers will be in our face.
Nobody wants to face it that close.
We have to address this issue before we move on in training. Many will claim you can't miss at this range. Until you learn the dynamics of it, your hit rate is not good at such close range. You can't extend the gun out in front of you at such close range, and in the process of drawing a gun you have to figure out where to stop the gun and fire. The hand and eye coordination is pretty slim in such a case and that is without any stress.
