Well thought out choice for sure. Lots of folks would choose something different without putting any thought into it. I have been guilty of that in the past as well. The revolver makes a great choice for self defense because if you get a misfire, you just keep pulling the trigger, and another round is in front of the firing pin. Odds are, there won't be 2 misfires in a row. Just my opinion.
For my wife and I, we keep a HK USP Compact 9mm on the bed stand at night loaded with Speer gold dot ammo. I don't remember off hand what the weight is, however it is the issue ammo of the local Sheriffs Dept. During the day, it stays in a 1/2 ton gun safe when I am working, and is carried at all other times. My wife shoots it well. Often enough to be familier with the safety, and functions, but not enough for general practice.
