I have had a series 80 Gold Cup NM for a few decades now. Despite its shooting well out of the box, I bought a new match barrel for it and sent it off to the late George Madore for additional work. He sent the gun back with a fitted bushing, an even better trigger - the FP block disconnected from the trigger - and the match barrel still in its wrapper. His note was that the Colt barrel was as good or better. Included was a target that was as good as any shot with the top shelf guns of today. The gun still shoots better than I do after more than 60k rounds downrange.
Would I carry it for SD? Sure. Very few failures over the course of its use and every one of those can be attributed to a problem with the hand loaded cartridges. The gun has never fired a factory load.
