The revolver would be for home defense and for carry. She is applying for her CWP.
I have various other firearms that can be used for home defense (remington 870, AR platform, other revolvers and so on). But, I wanted to start with a simple firearm and add layers as time progresses. I want her to be able to know one gun well. Much (not all) of the philosophies of home defense should transfer well to the other firearms when the time comes.
