That IS outrageous. I have 4 Kimbers. One is an Eclipse with night sights. I bought the gun used slightly, a safe queen. The night sights were pretty dim so I called Kimber to ask if the sights were still under the 10 year warranty. The fellow I spoke with said the gun/sights were 9 years, 11 months old & to ship it right away to Kimber for replacement of the night sights. I did and got the gun back in under 2 weeks with new night sights and a gun that was sonic cleaned, looked better than brand new, squeaky clean.
I was mightily impressed.
I'm upset to hear of your woes and can't understand an outfit like Kimber pretty much give you a royal screwing.
Perhaps you could call them and maybe get hold of someone a good bit more cooperative?
