I have a 92 pre-b that i am going to get the frame refinished on after an incident with a sonic cleaner. I have replaced the extractor spring and recoil spring but when they have it apart for painting is there anything else I should replace. I know I should probably get a new mainspring. Is there anything else I should replace? The magazine release spring seems kind of weak. Isn't there also a slidestop spring? I want to make a list of things to order from cz so i can get them ordered before i have the work done.
