Here, no NICS, no call, just 4473 and that, if paper, goes in file cabinet in shed at home. Seems most dealers here have a shed out back where they keep all that stuff. I have heard though (don't know if true or not) but some have trash burn pile nearby.
Some guys thought if registration/turn in of those suddenly necessary, the wind might blow the wrong way. Dunno but you know how you hear things, people talk, word gets around stuff happens. I do not believe it. They all are good legal proper dealers around here.
