It fits her hand. That's a biggie. Range and safety training included for $200. I wouldn't hesitate another minute. A decent gunsmith should be able to re-blue cheap enough, if you decide it's needed
I agree with everything Doug just said. Especially what I highlighted.
I was checking out my buddy's Glock .45 yesterday and we were having this discussion about me getting one similar. There are criteria for me purchasing a handgun: it can't be too big in the caliber range, yet still have power. It also has to be something my wife would be comfortable shooting and that means fitting her hand. She's 6'0" and has bigger hands than I, so that opens up more possibilities, but it's got to be something she is comfortable with.
