My buddy bought his wife a Walther PPS 9mm. He bought himself a S-Blackhawk. Wife likes the SBH with mag loads over the PPS (trigger is painful).
So get her to the shop if your intention is for it to be her weapon. If you have a place that does rentals around that would be even better. Both of the pistols you mentioned are very mild recoil. Not to say your wife would have an issue with recoil, but they are much diferent than a mag revolver.
Concentrated power is not rendered harmless by the good intentions of those who create it.
