A colt gold cup is not the equivalent of a gallardo.
It is more like comparing a camaro to a corvette. The corvette should be able to outrun the camaro under all conditions, but is it worlds different than a customized norc? Christ no.
The only reason anyone would compare a CGC to a lamborghini is that there aren't a lot of REALLY high-end 1911s in this country, so people here often think a gold cup or a kimber or an STI is a top-notch 1911.
Gold Cups are nice match-grade 1911s. They aren't unobtanium super-pistols. Depending on how much you spend, a Norinco could be built that would greatly exceed a gold cup. A few people here will have seen Wilson Combat customs that were built on Norincos...well, those are a hell of a lot nicer than a Gold Cup. Therefore a great 1911 smith could definitely make a better pistol out of a Norinco than a factory gold cup would ever be.
It would probably cost a lot more than the CGC by that point, though. So the real question is, "how do you want to allocate your funds?"
