John,
It's your decision. Go to
http://www.louderthanwords.us and start clicking on all the gunsmith's web sites.
They all have photos of their past work along with prices for each upgrade along with packaged upgrades.
If you want someone else's gun - give it to the smith of your choice and tell him he has carte blanche.
Nice Gun, or should I say, nice grips. I have the Combat Gov't prior to the Special Combat Gov't. I took me six months to settle on the smith I wanted to do the work and fortunately, his list was two years long. I asked him to place me on his list with an initial order, with a caveat that I would be changing some things in the package I decided on. I spent the next year of the waiting time refining what I wanted done to my gun.
I still have four months to wait and am not guaranteed a date yet.
