I am sure you will get a lot of good advice here on FR, but what is comfortable to shoot for practice or self defense classes is so important. Get some range time BEFORE you buy.
I have only had one incidence of flinching, it was a nightmare. I found it is nearly impossible to hit what I was shooting at with my eyes closed.

I find if I shoot with my eyes open I don’t flinch so much! ;)
I agree, take her to a range. She should go with the largest caliber that she can comfortably shoot with accuracy.
