There are indications that sales of guns are very high. At last that can be implied by the shortage of forms that have to be filled out by gun purchasers.

I haven't seen any analysis of why gun sales are up. I suspect there is fear that with the Democrats now in firm control of the government, there will be laws passed to stop or at least impede sales of guns.
