I carry a lightweight .38 snubby in my purse. It's a purely utilitarian defense firearm. I'm relegated to standard .38sp rounds; no +p options. And frankly, I wouldn't think anyone would want to. The lightweight nature of the firearm means one helluva muzzle flip. Recoil isn't that bad with .38s, but the +P might not be the same.
It's grip is small, even for my short fingers. And that particular fact means it's harder to maintain good control when it goes flying up. An inexperienced shooter or one who carries because it's the prudent option but doesn't necessarily enjoy carrying or shooting would probably not like it.
I don't like it. But I can tolerate it, and I'm willing to suffer the drawbacks for the benefit it conveys. Purse carry really limits the options in firearms, size and weight are difficult to overcome.
She definitely needs to be able to try it out. Despite the common refrain, snubbies are not necessarily ideal defensive firearms for newbies/women.
