It has the 'SIS' slide serrations on a stainless slide?
I would have inquired too. Those SIS models are good lookers, it's ashame the two tone is too good to be true.
I found a post through a google search where somebody is selling one and had the slide sent to Kimber to be refinished for the two tone look and he's asking $1250. Link below for reference

Would this custom work hurt the value?
