I highly doubt that. As far as I know... FFL's don't stock inventory from retailers (like PSA, et al) at retail pricing for resale. They use distributors or enter into dealer agreements directly with the mfg's.If this contagion continues, FFLs who depleted inventories are going to have a more difficult time restocking their racks. This will be another unnecessary obstacle impeding their path to post Measure 114 adaption.
As such... none of these order/ship restrictions for end buyers will have any impact on gun shops ability to restock their shelves.
