Hey Bill,
Nice going, when the whisper arrives, share the excitement of opening her up, and teach your GF how to work and shoot it. Let her beat you now and then to keep up her excitement and interest.
I taught my wife shooting when we were going together, now she has several pistols, and you can bet, I don't give her any crap !!!!
Good luck with your new Baby, and be gentile with her ! :-)
