The other limitations to this come from case law. It must be direct (Don't stop at the bar) It must be a fixed location(Not a courier or taxi driver) and it must be in reasonable proximity (Not a cross country airline flight IIRC) So much simpler to get the permit. The Lawyer's first 2 hours on you...

I have a very nice S & W 22LR snubby revolver that does not have a heavy trigger or kick - she might be able to use that.
