Registration, databases, federal permits, cops, guns ..............
Unless your state sucks and requires an ACTUAL registration of firearms, your guns are NOT registered. The only fed registration is the NFA registration.
When you purchase from a dealer, the make, model and serial are recorded on the 4473 form. It is not included on the NICS Phone call.
I could make a list of a bunch of guns i have, or "have", or wish I had. Why would one feel compelled to provide that infornation freely? Do you feel the need to show off? Is it some immature game of oneupsmanship?
Why do you feel it necessary to list your guns?
