Glad nothing bad happened black Friday.
I've open carried into Cabela's several times. All they ever ask me is if I am planning on un-holstering in store. If I was then they want to check it clear. I am not, so I just keep it loaded and holstered and there is no problem.
As far as gun tracing (Viper please correct me if I'm wrong) but I think it's based on the serial number. I'm pretty sure the they can track serial number from the manufacturer to which distributor. Then by serial number again from distributor to the FFL. Then from the FFL it's paper traceable to the seller. It would take a while but serial numbers are part of the sale. Would be easier if the FFL ordered direct from the manufacturer.
