Just got off the phone with @Stripe and we've found a solution to the issue. I had the opportunity afterward to talk with them for a while about general restrictions on the firearm industry and they let me know it's something they're working on. It appears we can in fact pressure some of these companies into eventually changing their attitudes. Whether the firearms industry will ever trust them is yet to be seen but it's interesting to hear they're moving in that direction because up to this point I've never heard that sentiment expressed by any of the major players. Keep on speaking up, guys.
