I take it you are referring to the Pro Elite, vs the Pro CDP.
Both were built by the Custom Shop, the Pro Elite was the previous model.
There was a thread here that compared the 2 side by side, and had pics, not sure what happened to it.
There were subtle differences between the 2, but the high points were that Two-tone being reversed, and the front strap was checkered finer with the CDP, the Elite being 20 or 25 LPI, I forget. Both featured most of the same mod's though, Rosewood Grips, Ambi's, Night Sights, Soap-Bar Melt, etc...
Personally, I like 2 tone guns, although I prefer to have the top black for glare reduction. The Pro Elite was that way.
I considered a Pro Elite, but I really wanted a Compact, same slide, Officer's frame. Personally, I feel it is a better option for carry purposes, though I have no problem concealing the full size grip.
