DA/SA w/safety are not found in great numbers. The ones that come to mind are the FNP9, CZ85 (and probably the 75), and Taurus 24/7. The safety of the Taurus will also de-cock the weapon too, if desired. My wife finds the CZ and Taurus to fit her just fine. I also think that these, along with the Walther P99, fit my hand better than any other service handgun.
The S&W M&P and the Springfield XD's can also be had with safeties, but are not DA/SA. You might also look at the older Ruger P-series handguns. I don't care for them at all, but I think they fit your criteria.
