There is precedent for credit card issuers to ban the purchase of completely legal products. If Visa and Mastercard are unwilling to act on this issue, the credit card processors and banks that issue credit cards could try. There’s a chance that some of the payment processors would stop handling gun sales. While Walmart stopped selling assault rifles in 2015, it might look askance at any policy by a bank issuer or credit card company to limit the kinds of products it sells. Critics of using the finance industry to influence gun sales might argue that such a move would be discriminatory against gun retailers.
