Guns

handgun recommendations?

I posted this in Answers, but I thought I'd see if any women out there might offer insight:

I don't own a handgun, but believe it or not, my wife expressed interest in getting one. I'm curious as to what handgun & ammo people recommend? It's for both of us to shoot.

1. Our 1st handgun
2. My wife is 5'6" 120 lbs
3. It'll probably be used at the range mostly (but let's say home defense too)
4. I'd like an economical ammo
5. Not against revolvers, but not exactly for them either (convince me otherwise if you like)
