Extra note of caution:

In the event that you can obtain your 9mm revolver prior to moving to NYC/NYS you're technically going to be forbidden to own it until and unless you get that permit. NYC for sure. I do not know what the procedure is for telling the Firearms Authorities in New York City that you want a handgun permit for a gun that you already own but I can assure you that they will take a very dim view of your possessing it without their permit. "I had it before I moved here" will not cut it as far as I recall.
