If you want it work in rain and snow it must be something like that...

Most likely your cz is not broken. You can get similar symptons even unburn powder if it get under sear cage and affect disconnector. Take slide of and flush the frame whit hot water. If this doesnt help remowe sear cage by removing safety lever. Like i said, even small amount dirt wrong place can affect trigger.

Normal cz trigger spring is something about 2.8lbs. When making changes trigger pull you dont want any light primer strike problems. Thats why you also play with trigger spring. Mainspring also make huge differend how fast slide moves so its not best way to change trigger pull.

New trigger spring and problem solved.

Looking for new 9mm pistol and dvc 3-gun is top of the list. Any thoughts are welcome since we dont have any(?) in here europe.

In Europe cz use red loctite type glue on sights. Heat sight properly and they will come off easily. I have also notice that rear sight come off right to left and new sight go in left to right. Freezing new sight ja and heating slide might help but never really notice any difference. Shadow standard sight also have a small lock screw and that is also need some heat to open.

More interesting is why they broke. Cz slidestop killer is to release slide full spring tension on empty gun. If you escort slide on empty gun you can doudle or triple slidestop life. Now my slidestop average life is about 40-50k.

I change my first shadow barrel after 40k, all rifling was gone. At the same time my friend has shot 70k without accuracy issues. Bushing is ok after 60k so i would change barrel first.

STI dvc 3-gun?
