A> SWMBO nominally can't (or won't) shoot my daily carry. She has arthritis, can't operate the slide, and is intimidated by autoloaders. Not only that, she is recoil sensitive and knows in her head that she doesn't want to shoot it. After all, I did tell her that the recoil on that little dude isn't pleasant.
B> I'm not really concerned about that. The only time she'd need to shoot it is if we weren't at home (she has her bedside .38 but doesn't carry) and I wasn't able to shoot it myself -- if I was injured and down, in other words. In such a case, I'm sure that she'd pick it up and use it anyway. If I were down, it'd be a life-or-death situation and she's not one to go down with a whimper. I have shown her how to use it, she understands the operation well enough to pick it up and return fire in an emergency. I can't really ask for any better than that from her.
