I've owned '80 Series Colts since they were introduced in 1983. I have used various '80 Series guns for training, qualification, recreational competition, CCW and as duty guns. Within my humble experience, they have been more consistent in overall quality, more reliable, with as good or better trigger quality, than the Series '70 Governments and Gold Cups I bought back when they were in production. I've never encountered a problem with the '80 Series components, other than what I've seen with Bubba modified guns, whether done by "gunsmiths" or not. I trusted '80 Series Colts enough to carry one 40+ hours a week for several years. Still works reliably, and I still trust them...ymmv
BTW, I'm a Colt armorer and, like others I'm sure, have done some informal experimentation with the '80 Series Colt with and without the Series '80 components installed. It made less than 8 oz. difference in trigger pull weight ,and no difference at all in any other aspect of trigger action. People blame the Series '80 components for bad triggers, but trigger specs didn't change between the Series '80s and previous models. The hammer, sear, sear spring and mainspring, that actually determine trigger quality, don't care if the fps system, etc, is present or not...
