If she likes the P32, shoots it reasonably well and will actually carry it...consider yourself lucky. And give it to her, with a smile.
In the mean time, have a look at a concealed carry/personal defense website by and for women, and share with your wife:
www.corneredcat.com
If you spend some time there you will both learn something. Hopefully, one of the first things you will learn is to
let her choose what she wants to shoot/carry.
