I've been patiently waiting for this thread since you mentioned it recently.  I'll definitely follow and and greatly appreciate the time and effort spent putting it together!

My trigger bar is just like that one.  I stoned it a little bit (looked like the second pic you showed) but didn't want to go to far.  Will stone it some more.  Going to wait to break it down and finish the job, though, until the end of this thread so I can do it all at once.

Quick question David.  What is the recommended finish to put back on the action bar after you stone it??

David, are you going to have a new modified trigger bar spring available?

When I spoke with him on the phone, he recommended just gently bending it. It doesn't even need to be removed from the frame. You can just pivot it out from under the trigger bar and apply pressure until it (relaxed) sits as shown in the image above.

I'd guess the next step is mirror polishing some crucial areas on the bar.

Thank you David, we would be lost without you!

Yes, David is a CZ guru.  My wife tells me that patience is not even in my vocabulary.....I guess I am just anxious since I picked up my new P-09 yesterday.

I would smooth out any metal to metal contact on the parts not being upgraded: hump on trigger bar that contacts the slide, Tab on the trigger bar that contacts the disco, bottom of sear, hammer strut, fpb plunger and cavity. Would polishing the area of the trigger bar that contacts the roller be ok? There's a little friction drag with the slide along the polymer area of the rails that could use a very slight sanding down with a stone.

I held out not doing any modifications for a long time. The repeated testimonies here persuaded me to give it a go. I now have an 07 and an 09 with the upgrades and polishing described in this thread. It really makes a difference in accuracy as things are not moving as far and due to the polishing are moving with less friction all helping the gun to "wiggle " less when fired.
I did not buy a different trigger bar spring but modified mine to mirror the photo shown above.
I do have a question.  How is the slide return spring put onto the factory rod as it seems to be all 1 piece?

I'm almost positive that the the guide rod/spring assembly is made in a machine that inserts the guide rod into the spring, compresses the spring, then swedges and trims the end of the plastic guide rod to permanently capture the spring.

I have a thread in this subforum where I'm documenting the results of my testing of Glock 19 aftermarket springs in combination with a CGW stainless guide rod in my P-07.

If you have a P-09, you can use the same recoil springs as the 75 and SP-01 using CGW's P-09 stainless guide rod.

I had envisioned something alone those lines. I wondered if the tip was heated to form the flat capture top.

     I have noticed the other day in my P-09 that the guide rod has a cap on the end that goes into the front of the slide. That cap can be screwed off to remove the spring if i am not mistaken. I saw that mine was sticking out quite a bit. I just screwed it back in.

Probably a flat spinning tool that presses down from above and forms that cap at the end with friction heating.
