Had one...helluva nice gun...sold it like an idiot. As I recall, overall quality was nice. I wasn't near the shot then that I am now so I can't comment on accuracy, but I am sure it was as good as any other Gold Cup. I have bought, sold, and traded many guns over the years. There a very few transactions that I regret. Letting that Gold Cup Commander go was definitely a mistake.
That is dirt cheap... all the Gold Cup Commanders I've ever seen for sale in person or on the 'net were $1,500+.
The one I've shot a couple of times is a two-tone (stainless frame, high polish blue slide) with Novak night sights (!). It came from Colt that way, and was either a special run of a special run, or a custom shop order. Pretty nice, but for the prices they are usually going for they aren't worth it IMHO.
Well, I picked it up today and it looks like a steal. It is nice and tight with a very good trigger pull of 4 lbs on my scale ( I should be able to get that down to 3-31/2 )with no creep or overtravel. It has a couple of scratches and the ever present idiot mark that will easily polish out. I will give a range report when I fire it.
