Jim,
I don't own a
and probably never will, that being said what works for one kind of handgun usually works for others, this is basically what I do so maybe this will help.
you, your Wife and your Daughter all need to go out and shoot some handguns, find one that fits all three of you and buy one for each of you plus a spare or two, then get a ton of magazines, load them up and stash them and the spare handguns around the house.
if all three of you become familiar with the same pistol and all your magazines are the same then you should be ready for anything no matter what part of the house you're in.
