Nothing wrong with .22, of course. They've got plenty of uses. But for home defense? I'd rather have a big ol' can of pepper spray and a baton than a .22.
"She" isn't comfortable with firearms. (we're working on it)
In the meantime, we've got dogs for early-warning and deterrence purposes, and I bought several 4oz cans of the spray used in these videos:

Do you know if a .44 mag would go far after hitting the thing?
I have a Rossi Lever action I'm a better shot with than my .22 Mark1.
The only thing I understood in your sentence is Armadillo.
A .22lr can be dangerous out to over a mile, the .44 will go quite a bit further than that. Obviously, with either one, you want to make sure you're shooting into a good backstop.
.22lr is considered marginal on anything larger than a rabbit; .44 magnum is considered adequate for defense against bears. I'm pretty sure a .44 magnum will go straight through an armadillo like a hot knife through melted butter.
