Trigger bar issue, advice request (modifications made).
« on: February 15, 2015, 04:15:04 PM »
Back when I got my 2014 Shadow Custom I noted that there seemed to be friction coming from the trigger bar. I have never adjusted or removed the trigger bar springs, but recently, I removed my grips (for 3d printing project) and saw that one of the trigger bar "hooks" wasn't in the trigger bar groove. In fact, it wasn't even touching the trigger bar. So, I decided to do a teardown and clean and see what I could see. First, what I saw with the grips removed:



As you can see, it's hard to tell that it isn't aligned properly, even from this vantage point. You certainly can't tell with the upper off and looking down. So, I disassembled, and examined the trigger bar. Here is what it looks like:





Here you can see one side is heavily worn (pistol has 1400rds through it). The other side shows no wear at all. I would chalk this up to "it's just a little wear, probably smooths the action, no big deal", until you look at the profile of the bar from below:



One side is noticeably thinner, I would even say significantly. I am a little worried about this. I would hypothesize that the misaligned spring was riding on the outside of the trigger bar, pushing on the opposite side, but it never seems to touch the trigger bar at all while dry-firing. So, I think the one hook that is touching is making this happen. My current idea is to just realign, and maybe bend the spring up on the side that isn't touching. There is very little space on the outside of the trigger bar inside the frame, so getting alignment on this might be tricky. The gun performs flawlessly, but the excessive wearing is a concern.

So, my question is should I just align the thing and keep an eye on it, or should I get another trigger bar? Leave it alone, damage done, not a concern? Anyone else have issues with the trigger bar alignment? I have never touched the spring, I think it was like that when I got it and I just never noticed. Any other thoughts/advice? Trigger pull is silky smooth, it may be done wearing, but can't say for certain.

I think I would realign and keep an eye on it.  But, maybe it's just the picture, the last picture looks like the TB is bent a little to the right? If you need anything else from CZ USA, go ahead and order a new TB just in case and save on shipping. Once you get the spring back in the groove it might pull the TB back over?

I think that is just the picture, the trigger bar didn't look bent.

That's good. Hopefully just readjusting the spring will take care of it then.

Why you have it a part do a trigger job. polish the other side of the trigger bar.
this will help.

I had a very smiler situation with my SP-01 trigger bar and spring. My trigger bar was also mostly worn on one side. In my case one of the grooves in my trigger bar was off center and quite shallow. I re-profiled the shallow grove with a Dremel and thin cut off wheel. Then reset the spring position. I have found it common that the trigger bar groove can be pretty ruff as well, i like to smooth it out when i am doing all the polishing.

I believe you are on the rite track with just changing the spring position. A few of my other CZ's also have trigger bars that have worn unevenly, never been a problem as long as the gun functioned i left it alone.
Will work for CZ pics! (including but not limited to all CZ clones)

Bossgobbler,
Trigger job already done as per my previous posts.  :) Good looking out though, would have been a good time to do it had it not already been done by CZC, then myself.

Tok,
Ok, I think I will just reset the spring position and keep an eye on it.

Tok +1.
If it runs don't fix it.  Having one side spring out will make it run catty whompus.  It can cause intermittent trigger reset problems too.
There's a post here from schmecky (David Milam) and others showing key areas that benefit from polishing.

Thanks for the reinforcement 1SOW. I have already done the requisite polishing as per the threads here. I will re-align, set it and keep an eye on it. I will post pics of it after I get it set if it seems worthy or if anything "interesting" comes up in the process.

Sorry, But that trigger bar did not look like it was polished to me.  First pic of the side of the trigger bar does not even look like it has been touched.

The sides of the bar were neither polished by czc or myself, presumably as it is not intended to be a friction point. Have never seen the sides being polished in the reading I have done. The top contact points/hammer hook/sear/hammer spring strut, etc are all mirror polished. I guess you could polish everything...although it might loosen things up a bit.

I believe the trigger bar/frame contact area can be a friction point to varying degrees depending on the specific pistol.

While polishing the sides of the trigger bar that contact the frame is not uncommon, i have not always found it necessary on all of my CZ's to achieve a smooth trigger pull. It really depends on the specific trigger bar and pistol. When done correctly i do not believe that the amount of metal removed while polishing would be enough to make a trigger bar it any looser in the frame.

1SOW,
I followed David's post and made sure all the areas in that thread and in the "trigger job" thread were done on my pistol. I detailed this back in January (http://www.czfirearms.us/index.php?topic=68523.msg476516#msg476516). After I did that work, it was very smooth, so I didn't give it another thought. While it isn't specifically mentioned that the sides were polished in either of those trigger job/smoothing the action posts, I do see that in one of David's pics there is quite a bit a wear/or it was worked on.  Good eye!

Thanks everyone for responses!

I will post before and after pics of the work I do here. Cheers!
