This is true, I use handguns like a ten foot long sword. I think at ranges longer than 10-15 feet the use of deadly force is questionable unless the assailant is armed and menacing, and if that is the case, you are likely going to be shot drawing your piece. In defense, ftlbs of energy absorbed is really important, placement and number of shells mean a lot less when 1300 ftlbs of impact energy just blew your arm or leg clean off. Same thing with malfunctions. Give me a large bore revolver any day, or a 9mm magnum (.357). Semi automatic 9mm makes sense for police, but not defensive carry IMO.

Reloading a revolver mid engagement? No thank you.
Defensive? Reloading very unlikely to be necessary. More than 5 shots fired? Likely you are going to jail regardless of circumstance.
if you really want to be defensive (here is my more than twenty years of defensive martial art experience) you put signs on your property in plain view that state TRESPASSERS WILL BE SHOT
and then you store your handgun somewhere safe that only you can access
and/or you get one of these ;)
