Help. Just bought my first Kimber But the gun is rusting already. I bought it just few days ago and the barrel is rusted. I haven't shot it yet. I brought the gun back to my LGS and complained about the rust on a new gun, but the salesman told me that it's common for Kimbers to rust, even new ones. Why is this and what can I do to stop it? Will sending it back to Kimber for them to remove the rust fix the problem?
