That article is full of outright common sense.

My wife carries a 9mm because she enjoys shooting it for fun and training, and she shoots it well.

I carry .38 Special +Ps instead of .357 for the same reasons. Ever since I heroically injured my wrist in the line of duty one night as a Security Policeman (by heroically falling on my ass), the "snappy" recoil of .357s and .40s hurts me, so I don't enjoy shooting them.

The .45 doesn't bother, and I think Cathy would enjoy shooting them, but that's not what we have at the moment.

Incidentally, what he says about even trained men and women shooting till their threat is gone, no matter how many rounds they are trained to fire, is also dead on. This was brought home to me when a gate guard fired 15 rounds from her M9 one night at a driver who had tried several times to run her over. She insisted in the following investigation, and to me privately later, that she only remembered firing two rounds. Guess how many we were trained to fire?
