Handgun stopping power, the eternal question. Marshall and Sanow's works were pretty much disregarded many years ago. Read Doc Rockets post above and look up Doc GKR.
If you visualize a line 4" wide tube running down the center of the opponent from the eyes to the bottom of the sternum shoot them there, continue shooting until the threat is stopped. If you always carry a gun that you can shoot to this standard and practice enough to do so quickly on demand you will then have maximized your ability to defend w/ a handgun.
That of course is my personal working model, YMMV.
