It's lighter than it looks.

I guess I'll need to do another gun to try another bluing method but I'm starting to get tired. My hands hurt.

I feel old for 40

Gun assembled.
Some function issues.

The slide gets stuck when racking it and returning back to battery. A lot of resistance from the trigger bar.

I suspect it is disconnecter related and that it is probably a little too thick in some areas.

Also in DA the hammer does not fall.

Gotta step away for a bit and research when I return.

Mangled the front sight roll pin using an undersized roll pin punch. No damage to the gun. It's been a while.

   A possible remedy for the DA Hammer not falling with the Trigger pulled all the way back is removing material from the underside of the Disco wings. Starting with a small bevel on the lower corner of the face of the Disco wings may be worth trying first.

I am not sure about the racking issue.
Will work for CZ pics! (including but not limited to all CZ clones)

So I removed the disco to check behavior without it.

I still experienced drag on the slide.

So started messing with the trigger bar support spring and that seems to have alleviated the problem. But the trigger bar is definitely not the best. One side has a channel with very little wall on one side..

I polished the wing of the disco and it fixed the issues with the hammer not falling.

At the moment I am at 7 pounds 6 ounce DA and 2 pounds 0 ounce SA.

The SA is fine. The DA is not.

I may experiment with trying to cut the channel deeper in the trigger bar to see if I can make sure it is consistent.

I have reprofiled the spring channels successfully on a few Trigger Bars using a real thin cutoff disk on a Dremel.

Glad that you solved the other issues.

I was thinking the exact same thing. It's gotta be really thin. I may try it tonight if I have the right discs

Good luck, hope you get it all lined out. I’d like to hear your range report.

On my transitional the front sight pin holes are offset. Boogered up 2 pins before I realized what was causing it.

I laughed out loud.
It's probably been 2 years since I've shot a CZ. Maybe longer.

If you thought this thread took a long time to get through, just wait for the range report.

I think I have the trigger bar channels much better now. Did some pretty precise filing and dremeling. The spring now has a decent groove to sit in.

But I'm still having issues with the slide hanging up.

Thoughts?

I'm wondering if it's a trigger bar timing issue.

1. It still did this when I removed the disconnector
2. When I pull the trigger the friction goes away
3. It is intermittent
4. Sometimes it's tight enough that pushing with my thumbs won't release it.

   That is an odd one. You said that it was doing this with the Disco removed, that leads me to believe that it is not a timing issue. The Trigger Bar must be dragging/jamming up somehow. How dose it run with the slide removed? Dose the Trigger reset ok, it looked like it failed to reset towards the end of the video.

It looks to be running fine without the slide.
That was an older video before fixing the disco and trigger bar.
