Call your local Sheriff's department they should know.
I am new to getting my handgun license and just found out I have to have purchased a handgun before my interview and fingerprint date. I would like to know how i can register a handgun I inherited from my father how past 7 years back? I would love to know....
Be very careful how you go about this.
Things have changed since I lived there but not a lot.
Call the NYS pistol club guys
