Hi there, so I finished up installing all the parts and everything seemed to function correctly at first, but as I've dry fired and played with the reset more I've noticed a couple of weird things:
My single action reset is actually happening
before the trigger does its normal reset behavior (for lack of a better way to describe it). So if I dry fire, hold the trigger, rack the slide, and slowly let the trigger go forward there are two points... the first one is a very subtle break, and if I get to this point and pull the trigger again, the hammer drops--the other "reset" is the normal behavior, with the audible click and the trigger snapping into place. Also, the SA trigger pull is noticeably heavier if I don't let the trigger get past the reset point.
However, sometimes when I do the premature reset and pull the trigger, nothing happens. Occasionally, after I do this and let the hammer return to its normal position, the gun also decocks, as if I'd pressed down the decocker lever.
I took off the slide and inspected the sear assembly as best as I could, but I'm far from an expert. The springs all look to be correctly seated, the lifter spring was definitely in place and providing tension to the lifter. Any ideas what could be wrong? Hopefully I explained this all well enough but if not I'm happy to upload some videos of the issues. Thanks.
Edit: I'm not sure if this helps but I did install a new disconnector and hammer bar... instead of trying to hammer out the pins of my old hammer/bar/disconnector I bought a new bar (from Cajun) and factory disconnector (CZ customs -

Edit2: I looked around and found someone who had solved the two-reset issue by tightening their trigger bar spring. I gave this a try and it seemed to fix the issue. There is still a slight snap/click where the premature reset used to be. Also, the gun decocking issue is still happening sometimes, and there is still a heavier SA pull if I pull right at the reset point.
