My EDC for the last couple months has been the 3.5" congress, in the amber-ish bone, pretty good fit, much like RR. It does have issues with the springs not being flush when open, or closed, and different in either position... something I've not seen in RRers, but the bone fit is a lot better than a lot of RRers, so its right on par with them--so much that I bet they come out of the same factory-- It's nice and crisp and consistant from blade to blade on spring snap, 'walk n' talk' too.
As to the steel and HT, I think its real good; Got a blade dedicated to steak night/dinner time- doesn't roll the edge on ceramic plates any worse than any other brand so its not reeeeal soft. I get great edge retention with my RRers, and the colt seems to be the same steel/HT so far, has handled everything from christmas packages, heavycardboard auto parts packaging, and... Well, lots of boxes.. to scrapping wire insulation, cutting vacuum and fuel hoses, whittlin' kindling/tinder. not gonna hold an edge forever, but I got a couple weeks on it before it dulled noticable, and its still not been sharpened after a month and is 'working sharp'.
my only problem is that big 'C' stamped on the bolsters is so ugly... especially crossing the threaded/groove on the bolster... But thats an personal preference, not a quality issue.
Have also got the 2 blade #' tear drop jack/peanut they make, and its on the same plane, same level of fit etc, and a friend has several the same, so they are at least fairly consistant in their production.
