Another thing - most of the data (anecdotal and otherwise) on humans getting shot by handguns is from when police are shooting criminals. Seems to me the criminal then has the maximum motivation to fight on - police have him cornered, there isn't a "fight vs flee" choice, only a "fight vs surrender". A criminal who finds his intended victim shooting back might face a clearer "fight vs flee" choice, since the criminal knows if he flees the victim isn't going to pursue him.
