This action is being considered by the banks that issue the credit

honor firearms sales.

We're not communicating.
The fix will be done by the vendor selling the items that the banks won't honor. The vendor losing sales will change the credit card reporting so the banks won't be able to tell that the item is a firearm, and the sale will go through. Your new Ruger purchase will say "Misc pet supplies", or something similar.

The VISA paper said "...won’t do business with retailers that sell assault weapons, high-capacity
magazines and bump stocks...".

The vendor would have to hide the fact that the items were part of the inventory, not hide the sale
of each item. By checking a vendor's web site a bank could easily see what the vendor carried. Or,
the bank could have someone go into the vendor's place of business.

I doubt Visa is in a hurry to blow off Walmart.
My guess is that if this really gets traction, there will be a
company, probably affiliated with NRA and the other shooting
organizations that spring up with their own card.
That 38% of the marketplace is certainly big enough to attract a bank.
Personally I think I would just pay cash or use a debit card if I was
buying another gun. I doubt that is going to happen tho.
