I bank with Wells Fargo, and I made it a point to have the branch manager confirm with his regional manager that OC was fine pursuant to state law. He confirmed, and I moved all of my accounts there.
So, they're not necessarily pro-carry, but they have a policy in place explicitly allowing it.
Wells Fargo is second place only behind BoA in carrying on with Operation Choke Point even after it's official death. They back Stripe. I'm dumping them immediately, becasue I've seen what they do to people who think the 2nd Amendment is a good idea.
I was about to buy a Tesla Model S, and to protect my investments elsewhere, I was considering a loan of drastically lower interest than the margins to be made on the investments. Wells Fargo approved me. I cancelled the deal. The interest alone was more than most people spend on a whole car...
They want to appease the individual customers and keep your money there, because they are receiving leniency in exchange for continuing to enforce Operation Choke Point of their own volition. The more gun owners they can screw, the better... If you're in business tho, watch out. Banking there is screwing your LGS.
