we are really in unknown territory here I suspect that the shipping company would hold all shipments until they can be delivered however I agree with James G that you should call both the FFL and the shipper with your concerns

Rich, this will probably depend on where it is at that time Sir. I would contact your local FFL and the shipping service once you get tracking information to see if you can have either hold your firearm due to current circumstances. We all just have to play it by ear. Stay safe Sir!
