If there is a range where you can rent pistols I would take your wife there. Of the pistols mentioned so far I prefer the M&P. When my wife and I moved to Va 7 yrs ago and could start carrying I did research and came up w/ a list of 6 possibilities for her. We weren't able to shoot all of them but shot half and handled all 6. She picked a Glock19. At this point neither of us likes it much, but we both shoot it just fine. The main point though is that SHE made the choice.
