congrats! and you got the 'di-CZese' pretty bad. I have 3 CZ's myself and a Kadet kit to ride on two of them. You can't go wrong with the CGW stuff! have the race hammer, 13lb main spring, trigger pin in my PO6 and wow, what a difference. I am getting a race hammer for my 40B and a few other goodies. Anyway, I have the Mepro's on the PO6 and love em, I actually tried the tritium front sight one time , but took it off. too small. and what I really like is no matter what time of the day. those Mepro's are just dang easy to see! I wouldn't hesitate on em at all.
cheers
