I recently got a CZ-85 Combat specifically for Production following research and love it. I used it to win the third USPSA match I've ever competed in. I recommend the 85 Combat and also "The CZ Connection" as a source for these and other CZ pistols, based on my experience with price, availablity and service. http://pdmall.com/CZC/pistol~1.htm
For smithing, I'm looking at Jim Miossi Gun Works LLC http://miossigunworks.com/on_line_catalog.html, using his hard sear along with other parts (sights, hammer) purchased from Angus Hobdel http://ghostholster.com/cz_home.htm
