Most defensive pistol stops are psychological stops. This includes the bad guy running away when he sees you have a handgun and before he actually shoots or stabs you. The majority of psychological stops with a handgun are when the defender shoots the bad guy and causes him to flee even though the hits are not fatal.
Rob Pincus expands on this during his presentation at the 144th NRA Annual Meeting and Exhibits in Nashville, Tennessee, on April 12, 2015.
