Finally received my 4th CZ75b MCARBO kit that was on back order. Installation went very well, and a new 1/16" starter punch worked perfectly to start moving that stubborn trigger pin. I did install a new CGW floating pin. This MCARBO kit was for another polished stainless 75b that I recently picked up.
During spring change intervals, I reassembled the pistol to feel how the trigger felt. The first check was after the firing pin spring and safety retention spring, along with the hammer spring. Noticeable difference in both SA and DA, but nothing alarming. Next was the trigger return spring, and that had a larger noticeable difference.
The only spring left changing was the sear spring, which I haven't installed yet because I'm not sure I want the trigger any lighter than what it is now. I'm measuring an average of 3.0-3.1 in SA without the lighter sear spring, crisp and smooth. I didn't measure the DA, but it feels really close to my other 75b at 7.5ish. The other 75b with all the springs installed gave me a average SA pull at about 2.7-2.8.
I think I'm going to leave it without changing the sear spring.
I'll be at the range next week to make sure I have reliable ignition like my other 75's do with the MCARBO kit. I'll update after the range.
