Hello, I really like your work and the help you give this board. I have a SS Kimber compact that is broken in and is accurate and completely reliable. I was wondering which stock molded parts should be changed for longevety and reliability? The extractor was flat when new and I had to tweak it at the range, I'm worried about that, the slide stop, sear and hammer. What should I replace with better parts? (this is my carry gun) Also What do you think of the steel in Norinco's? I built one up and have heard mixed propaganda. when I dehorned it the steel seemed very hard but the sear and hammer did not! do you work on them? Thanks GTO
