This is the second genuine (ordered 2nd one direct from Kimber) Kimber safety that has broken this same way. The first time the broken piece scratched the heck out of the gun
I had to replace the original right side with a "bobbed" piece to accomodate the crimson trace grips.
The original right side safety seems to be made of much better metal than the bobbed one.
Pretty sure I got it installed right. Hard to do wrong...and the gun passed full safety checks after installation.
I guess I'm going to have to see what Kimber will do for me. I've not heard good things.
