Dosey,
I URGE you to do what it takes to start her with a .22.
There are lots of gun snobs that will tell you differently, but I bought a Phoenix HP22 used for $75.00 a year or so ago, and have probably put 2000 rounds through it since with ZERO trouble. Oh, and I cleaned it for the first time last week!
I started my wife on that gun.
She shot ONE magazine through it (had good eye and EAR protection), laid it down, and said "this is lame. Give me my new P32. I wanna try it."
She was a natural!
I had her try my Ruger snub loaded with .38 specials during that same range session. Again, it was about 3 shots before she handed it back, and said "give me back my P32. It's just right".
(MORAL: women will tend to find their OWN comfort level, you just provide the platform)
Debate about one-shot stops aside, she is VERY accurate now with her P32, and knows that if ever the SHTF, she's going to empty all 9 rounds and bug out. (one in the pipe, 8 in the mag using the +1 extension). She always has it with her, and we're both confident that if she does her part, it will do its part.
Good on ya, Dosey! Let us know how it goes.
