Installed a Greider short trigger on my Crimson Ultra Carry II today. Just a little work with the file, not too bad at all. Pre travel with no manipulation (greider doesn't have the tabs) matched stock kimber trigger within .005. But to my surprise the kimber factory adjustment on the pre-travel/ takeup tabs seemed to be set to .040, less than the .060 everyone on this forum has recommended. Gun has approx 1600 rounds with factory trigger with no problems. The Greider measures slightly more with .045. Passes all function and safety checks. Let me know what you all think.
