Hiding in plain sight....
My assumption...that guy had some "out of body, probably drug induced state." But you know what they say about assuming!I had her looking at a 19 but then her brother told her a story about a guy that took 16 shots from a 9mm and has her convinced it is not a good round.
The 19 is a great gun. See if you can get her to shoot both the .357 sig and the 9mm to find which one she is more comfortable with. I agree with G29sf, that the .357 may be a bit big (in terms of recoil) for someone that doesn't shoot often. Then again, she may love it!
