If it was blue, it's a Royal I believe. Custom Classic w/black coating in Phoenix area can be had for around $570. Think the Royal is at least a hundred more.
That is a great price. The best I have ever gotten is a blued compact aluminum (with holster, 4 mags, a two mag holster, 25 rounds of defense ammo, and box the gun came in) for 500.
There is a Royal "model" Kimber. It is listed in their 2001 catalog. It has all the features of the Custom except it has a deep polished blue finish. It also comes standard with rosewood grips.
