I will be honest I have never shot anyone so I don't really know firsthand what happens when the bullet meets the body. I truly hope that I will continue on in life without that firsthand knowledge
However, I have read a lot of internet posts that seem to talk about people getting hit with multiple shots yet not being stopped. I would assume that one bullet hitting a person in any part of their body would dramatically slow them down a bit. If I were shot in the leg, then I am not going to be good at running. If I were shot in the arm, then my legs would work, but I would have to hold my arms and hand slowing me down a bit.
So how many times have you personally seen someone get shot and still keep on the move to the point where they remain a threat against you? I have read news articles about it happening, but how many times does it actually happen where a double-tap fails to substantially slow a person down?
