As others have said they are Kimber Raptor grips, Kimber does not, will not sell them. Occasionally you can find them on ebay, I've seen them go for as much as $100.00. You might have some luck posting something on Kimbertalk.com.
Kimber website I’m sure you’ve seen doesn’t have those exact but lots with Kimber logo, I think I have set of warrior grips unless given away but that’s not much help, those probably worst looking kimber grips anyway
Those ae the grips for the Kimber Raptor. A few years back I tried buy a pair from Kimber and was told that the do not sell those grips to the public. I stated that the once that I had were cracked and was told to ship them back for an exchange providing the gun's serial number. I have seen them for sale on EBAY.
