SOLVED!! DA will not work after internal polish job & RRK install. Seeking help

[myczaccount]

Hey guys. A bit distressed right now. I followed the sticked instructions (and those youtube vids by "abyss1232" per recommendations of others) for internal polishing. Everything seemed to be going well until I reassembled and now the DA won't work.

It is an SP-01 Tactical.

It appears the trigger bar won't properly engage the sear cage unless I move the hammer ever so slightly back. See attached pics.

Pic 1 depicts the space between the trigger bar and sear cage:

Pics 2 is properly engaged after I manually pull back the hammer a tiny bit:

I should also note that when I manually "fix" it and pull the trigger, the DA is very very heavy and not how it seems it should feel after a polish job.

Is it possible that I polished too aggressively and removed metal from the trigger bar and ruined it?

Did something happen to the reset?

Any input is greatly appreciated. Like I said, a bit stressfull...

Which CZ is this?

Just so it can be ruled out.... Are you only trying it as is or did you also reinstall the decocker and the slide with same issues?

Do you have the screws for the pre and over travel installed? If so try backing them back into the trigger and see if that helps the reset, then adjust from there.

If same issues with it completely put back together.... Check your trigger bar springs. Make sure they are both riding in the grooves, with a bit of upward pressure.

If the springs are good, call CGW in the morning. The new disco with the RRK may need some slight fitting. Or they will probably be able to better diagnose[emoji6]

Unless you got real aggressive with polishing, it should be fine. Did you remove actual metal? All you have do with polishing is smooth it out. You don?t want to remove tooling marks etc.

That?s all I can think of.

Thanks for the input. I completely reassembled it and noticed DA not working. I am going to check the trigger bar springs. Thats a good lead. Where can I find resources on how to make sure theyre properly placed?

Edit: Seems the left side trigger bar spring isn't lining up in the trigger bar. I want to note that I never removed the TB springs during polishing. The screw was too tight.

How can I get it to align properly?

I use a pick to move those tabs around. You should be able to grab ahold of it and just gently tweak it the direction it needs to go. Might take a couple times. IIRC, when you pop the springs out of the grooves, they should sight about 1/8? above the triggerbar. (Should call CGW to verify) I use the same pick to pry up or push down the spring leg to get the correct ?upward? pressure. Just don?t use pliers, the grooves pliers make can cause a weak spot in the spring.

Thanks. I was able to wedge the bar into the groove, but it keeps slipping back out. Sometimes when the left side is on track, the right side slips off. Is it possible that I may have pushed on the sides of the TB when polishing and slightly warped it out of spec?

Edit: Here's a pic where I press the TB against the left side of the gun. Is that too much clearance on the other side?

That gap does seem big, but it could just be the photo. Not sure what to say other than call CGW tomorrow. Sorry.

Thanks. I assume there needs to be some space in order for it to fit in the frame. I guess I?ll have to call. Only other thing I could think of is adjusting the TB springs, but I don?t see why I?d need to since I never touched them throughout the process.

I?m inclined to believe it has to do with the TB springs somehow being off. Anyone have any insight as to how to realign them?

Thanks

If you tried to remove the screw (it is staked) you may have overtightened it and caused the spring to bias towards one side. Look from the top down and make sure it's even. If not, try just a little pressure on the screw either way to get it to center.

Next, take the grips off. You can actually reach inside either from the bottom with a pick or from the top with s fingernail. Pull the spring to stretch in the the direction you want. When it springs back, it should be slightly closer to where you need it.

Thanks. I mentioned earlier that I left the screw (and springs) untouched the entire time. Nevertheless I?m thinking they need to be adjusted somehow because the left side won?t align in the grooves (pictured above). I?m just not quite sure how to achieve this.

By flexing it.
There's no elegant nor precise way of accomplishing it.

Pull the spring in the direction it needs to go.

Let it rebound.

Test.

Repeat.

Good luck. Try not to get frustrated. Reason and rational prevail.
