Thanks for the info I will check them out. Sunrise is about an hour south of me- not a problem.
This morning I purchased a 13# and 15# hammer/main spring from CZcustom for my stainless 75B. I think I can change that out myself but all those small pins and springs really intimidate me as far as any other internal work. I have read in other posts that if I change the weight of the main spring I would also need to change some other trigger spring and or firing pin. This is a range gun only and I shoot mainly 115gr FMJ rounds. Would I have to change anything else?
