I would say offer a variety, no one selection is good for all women.
What I have that I like:
I love my 1911, I put a short trigger in it and it fits me perfectly even though I've got short fingers, but I did fine with the stock trigger too. I put on women's shooting clinics and for those who attend the longer ones they get the chance to shoot everything we've got and I'd say 80% of them like the 1911 best.
I really like my walther P-99, it runs flawlessly over 5k rounds without failure in the past year. The interchangeable backstrap makes it a nice choice because you can use whichever backstrap fits your hand best. I use the small, my husband uses the large when he borrows it. I've let women use this in the clinics too and a lot of them liked it, my junior shooters really liked this one too.
The new HK P-2000 also has the interchangable backstrap and is a lovely gun, it's also ambidextrous so I know a couple of women who are leftys who have picked them up recently, and it is on my list to pick up soon. HK took the nicest features of the walther and put them into an HK, and you can't really go wrong with HK quality.
I like my P-3AT, it's a great little gun that can be concealed anywhere with even the most revealing outfit.
Don't rule out the little revolvers, a lot of women like them because they're simple to use and easy to understand.
