MAYBE MAYBE MAYBE!
I might have figured out an easy way to put the sear spring back in its slot in the auto safety..................
I had the same issues everyone else had (super annoying and time consuming and was never able to get the spring in place), what I did was decock the gun with the rear of the auto safety in the full downward position. I then used a forked tool l like the one made from the brad nail in the earlier part of the thread. I pushed the sear spring down as far as it would go, and slowly, carefully cocked the hammer while holding the spring down. When the hammer cocked, the auto safety slipped over the spring and it popped right into place. So far it appears to be in the same spot as my untouched 83 and it functionally checks out. You have to be bleep careful cocking the hammer so you dont bend the sear spring leg with the auto safety, but it seems to have worked and was very quick and easy. This very well may be the way that the CZ pro's do it at the factory, I guarantee that they dont spend as much time dicking with it as we all have.
Please let me know if this fix works for you, it may just have to become a sticky and save some hair from being pulled out and a lot of cursing.
PLEASE DISREGARD THE ABOVE INFO, ALL IT WILL DO IS BEND YOUR SEAR SPRINGS. I DID HAVE GOOD LUCK MAKING A SLAVE PIN FOR THE AUTOSAFETY AND HOLDING DOWN THE SEAR SPRING WHILE YOU DROP THE EJECTOR CAGE DOWN ON TOP OF THE SPRING AND THEN RELEASE THE SPRING. MAN THIS GUN IS A "PITA" TO REASSEMBLE.
