My grandfather acquired several hand guns during his time in WWII, however he has since passed away. These guns are being willed down to my father, who really isn't interested in guns, but will hold onto these as heirlooms. I've let him know that I would love to hold onto them, I've only seen them once as a child as my grandmother doesn't really keep old WWII guns laying around her house. I know one is a Luger and maybe a 1911 is in there. My question is, how would myself or my dad go about registering these guns? I have a FOID card btw.
