I've put my SS# on the form since the first time I got checked. I've always been put on hold and sent to a real agent. My normal FFL says I"m the only one. Not sure why. On the first gun I purchased the real FBI agent (2nd person in line as the first one is a clerk...) asked for my soc# if I was willing to give it otherwise it would have been a 4-day. I gave it, and he approved. Must be some schmuck out there why my name.
