I think 9's are lower on the train up time in an auto. I think the Army decided the same thing. Any chance you could take her to El Gun Shoppo to put a few in her hand to see how they feel?

Weight can be a factor with some young ladies. I wouldn't hesitate to give one of my daughters a good 32 or 380 to take to the range and most doggies won't stand up to them. One of my work friends got a light 38 special Taurus. One of the penitentiary shift captains called her and said when so & so gets out, he is coming after her. She got licensed, and shoots well with it, but it hurts her hand after awhile.
