Hay 191145 - DON'T TRADE THAT GOLD CUP. Buddy, that is a Series 70 GC without the internal firing pin block - which means it has a better trigger pull than the Series 80s and beyond.
I have read that the Colt repros are well fit and accurate but they sure ain't no Series 70 Gold Cup, that's fer dang sure.
If you don't want to pack a Gold Cup with its target sights, find yourself a Series 70 government slide that you can fit to the gun and put some combat sights on it. You will save yourself some money and still have a great combat/defensive pistol that, with a slide change, will give you the target you you can take to any match. By the way, with the Gold Cup slide, you can convert to the 400 CorBon if you wish and see which is the more accurate from that Gold Cup, the 45 or the 400 CorBon with range loads.
If you are absolutely intent on parting with that Gold Cup, please let us know directly or post it on the Swap/trade/sell forum and just sit back and wait for the bites to come in. Also, you can prolly find yourself a good used government model for not much and make that into your carry piece without losing that Series 70 of yours.
This is Mikey, and I hope I have talked you out of trading down from the GC to a gov't model.
