1st generation Kimber Custom, Ed Brown grip safety, Wilson ambi, Wilson full length guide rod, S&A mag well, Dawson narrow FO front site, and assorted small Dawson parts.
It's currently wearing Ahrend's ebony skip checkered grips.
Had the front strap stippled and the whole gun finished with Birdsong's Black T, which is tuff stuff...the guide rod's coating is worn but still there after about 4 years of shooting. Heck, the only shiny parts are the stainless grip screws.

Edited to add pics and you can see the Black T is still holding up on to the guide rod and barrel quite well.
