I have a old Ruger 22 caliber hand gun that was my grandpas. He passed before I was born and my grandma gave me the gun. How do I go about reistering this gun or do I even need to. I rarely use it but would like to go to the range and do some plinking some day. How much trouble would I find if I got pulled over by a cop with a unregisterd gun. Should I get this taken care of before Obama takes office?
