My wife isn't keen on the idea of her carrying....
I am pushing her to carry for her own safety.
This is just my personal belief: If an individual isn't interested in carrying or shooting, it is unwise to force guns on them. Too easy for them or someone else to get hurt by someone who isn't passionate enough to read, learn, practice and be proficient with both handling and shooting guns. My best friend ASKED me to teach her to shoot the shotgun and she did excellent. She practices with it. It is her bedside companion. If the time comes she asks me to help her be proficient with one of my handguns, then we'll start shopping.
I would not venture advice to the OP about pushing his wife to carry. I do worry about the consequences of pushing a gun into the hands of an unwilling individual.
