Creates the Second Amendment Financial Privacy Act

SB 1361, the Second Amendment Financial Privacy Act, prohibits financial institutions from requiring firearms retailers in Missouri to use a specific merchant category code (5723) for firearm sales or refusing payment card transactions based solely on that code. It also bans financial institutions from disclosing payment records related to firearm purchases unless required by law, protecting customers' transaction privacy. The law applies to firearms retailers physically located in Missouri and their customers using payment cards. Enforcement is handled by the Attorney General, who can order violations to cease within 30 days and impose civil penalties of up to $10,000 per violation for continued noncompliance after the deadline.
