I am dealing with a similar issue with my CZ 75 SA, except I am wanting to go the other way, and replace the stock extended safety, for a standard 75B style safety (the large one interferes with my grip). My problem is I am struggling to find a tumbler style standard LHS safety to replace it. As I understand it the 85C safeties are tumbler style (but they are sold out). Right now I am considering using a stainless LHS safety as they are also the tumbler style (but I would rather a black one).
Just to confirm, are you guys saying I can buy a standard D style LHS safety and use it in a SA tumbler cage, providing I change out the detent on the existing RHS tumbler safety?
My other plan is to try and find someone who replaced their standard with an extended and is looking to rid of their old one!
Thanks,
