Or if you're not comfortable with that just don't interact with the other player.
He most likely wasn't serious.
If you really think he was and you fear for your safety, contact security/police. Pretty sure a threat against your life is against the law.
Obviously also stay away from him if you actually think he's going to shoot you. What use is money when you're dead?
