She will not need to rack the slide in a critical situation with the SR9c. 17 in the mag an one in the chamber =18. When I first got the sr9c I was just sick because I could not rack the slide-after about 300 rounds that has changed-it is still not easy-but doable and I think when many more rounds have gone through the gun-it will be fine.
Men.. what you need to be thinking about is you dear wives in a multiple threat situation like this one
