KevinGibson- I have had the honor of introducing quite a few women to shooting handguns. I actually have quite a few handguns that serve only as trainers for new shooters. After being familiarized with a variety of autoloaders and revolvers, the split between wheelguns and autos has been right at 50/50 for new women shooters. Fit seems to be the biggest issue. Also, several have said that autos do not feel "real"- which is directly related to the confidence issue you mentioned.

I tend to think the best course is to take a trip to the range and let them figure out what they like!
