I like the concept, and I agree it would be a sharp looking piece when completed. However, I always thought that factory produced two-tone pistols were a combination of a blued or polycoat slide and nickel coated frame. Are you sure CZ makes a nickel compact slide? More power to ya if they do!
For the price of a new slide, you could have your current one refinished in any number of high tech coatings and colors. Food for thought for the 'academic' minded.
