CZ-85 Hammer Removal?
I have a CZ-85 Combat. I want to shorten up (and clean up) the SA trigger break. I have the only manual available, but it is for the CZ-75. I noticed an important difference between the manual and my CZ-85: the safety detent spring assy is not as described and I am afraid to pull the safety lever and launch the detent spring(s) into oblivion. How are the detent springs held in? Anybody know if removing the safety/sear assy will send them flying?
Please explain for the CZ-85:
1) Is it required to remove the safety and sear/ejector asembly prior to removing the hammer? I ask because:
I see the retaining pin that holds in the hammer mount (pivot) pin. It says to drive the retaining pin upward to enable removal of the hammer pivot pin, but it appears the sear/ejector assy blocks the retaining pin from going up. I tapped it lightly but it would not go up. Am I correct that the sear/ejector must come off first or is there a way to get the hammer off without removing the sear and safety?
2) As for shortening the SA pull, the height of the full-cock notch on the hammer clearly has some room for removal of material to shorten the SA trigger break. Any suggestions about how much to take off the top of the hook?
FYI: I noticed that the "safety" hook on the hammer in my gun is about 1/2 as tall as the full-cock hook... rather odd, as on most guns the safety hook is a shade taller to ensure catching the sear if the hammer follows from the full cock notch. Important in case anybody had considered putting a "relief" cut on the sear, as the sear would probably work perfectly with the full-cock notch but not capture the safety hook (very dangerous). Looks like the sear should be left alone (just polish the face).
I would appreciate any advice on the subject of sear/hammer mods for the typical trigger job from those who do them. I have done many, but none on CZ's.
Thanks.
