Title: CZ P-09 Second Pass - Polishing.
Post by: Tok36 on November 09, 2018, 05:49:41 PM
   Recently i got around to digging into my CZ P-09 FDE for its second pass. After shooting the P-09 stock for aprox. 500 rounds i had installed the full CGW Pro package parts without doing any other tuning. When time allows i prefer to just drop the parts in and shoot a pistol a bit, learn what i can and then go back in and do the polishing and further tuning on a second pass. Some of my CZs have been satisfactory after one pass. Others have benefited from 3 or more. For clarity, the CZs that require the most passes are the most fun because generally they allow me to learn the most. Sometimes i even wish some of my CZs would malfunction more often so that i would have a good reason to dig into them again. I may end up making some parts up to induce malfunctions so that i can lean more about them but i have not gotten to that point yet.

   Up to this point I have never had the same love for the Omega trigger system that i do for the classic CZ 75 variant trigger system. I am not as familiar with the Omega system and at this point. I do not really consider it an improvement over what came before. I recognize that in stock configuration the Omegas have been known to be better out of the box in some cases. Generally my CZs do not remain in stock config, they are far to fun to work on to be left alone. So the potential assets of the stock configuration are lost on me. I will continue to try and keep an opened mind and in time my opinion may evolve. I still believe that folks that are satisfied with a their CZ in stock configuration win big, no fuss and no added cost. However they do not get to have as much fun taking them apart.
   
   Out of the box and even once the upgrade parts were installed this P-09 had the worst Double Action i have encountered in a CZ. The DA was very heavy, it stacked allot throughout the DA pull and was quite stagey. The Single Action was alright in stock configuration. While it had some creep it was quite smooth, serviceable and easy to shoot. With the installation of the CGW P-Series hammer the SA creep was removed.

   The DA being my major issue, lets start with that. Using the P-Series tuning guide that Schmeky posted long ago (Linked below) i went after the trigger bar first. The P-Series single sided trigger bar arrangement differs from the 75 variants trigger two sided trigger bow. Due at least in part to its design and manufacture the P-Series trigger bar can shift and wrench against the side of the pistols polymer frame and negatively effect the DA pull. The issue seams to be the inconsistency of the side of the trigger bar that contacts the frame. As covered in the guide, to remedy this the trigger bar needs to be made more flat and consistent and then polished so that it slides across the frame during the DA pull rather than repeatedly jamming up. Reducing the tension on the trigger bar spring can also improve the DA and it only takes a few second to achieve.

With the assistance of my 75 Plus CZ pistol stand The P-Series trigger bar is removed.

The P-Series are a little faster to disassemble than a factory 75 variant. In a few minutes you can take an assembled pistol and turn in into an explosion of parts.

The P-09 Trigger Bar after a bit of sanding against a flat surface. As you can see this trigger bar was far from flat.

   After much materiel removal, polishing and deburring of the sharp edges the trigger bars is finished. I used only sand paper on this pass, 400, 600, 1K, 2K grit. The 2K sandpaper brought the finish close to a mirror shine, polishing compound did not seem necessary but time will tell.

   On to the trigger bar roller. The P-Series roller diameter and concentricity can significantly effect the DA. At this point i have only a limited understanding of the rollers impact on the lock work. My roller had consistent wear marks all around the roller. I checked its roundness and gave it a polish, again sand paper only on this pass. Polishing a round object of this size was a first for me within CZ tuning, i needed to maintain the rollers roundness so i made a jig for my Dremel out of some brass rod, mounted the roller onto it and polished it up. Here are some pics.

   I tried out a sanding tip that Schmeky posted in one of his guides. Sandpaper strips, one end taped to a reversed Dremel bit. With the sand paper rolled up around it so that once the paper is worn out you can tear off the outer layer and go back to work with the fresh layer underneath. This worked well and saved me some time.

   The pins were up next. Trigger Pin, Hammer Pin, and the Sear Pin. These are straight forward, chuck them in a Dremel or a drill for the larger diameter pins and polish them up. One of the assets of shooing a CZ a good bit before you do the polishing is the marks that use leaves on the parts, these marks can tell you allot in some cases. Note that some of the sharp edges where the diameter of the pins change need to remain sharp. The step down at the center of the P-Series trigger pin is a good example of this. I polished some areas of these pins that are likely unecessary. Please review the guide linked below.

   Now for reassembly. I run the decocking lever in my P-09 and this can be a tricky part of the reassembly. In the past i had just winged it and fought with the process of tucking the decocker spring leg into place. This time around i made a tool as forum member JoeL has suggested in the past in his videos (Linked Below). It made the process more easily achievable. Glad i took the time to make one.

   All said and done the second pass on this pistol significantly improved the DA pull. Before this process the sights moved every time i pulled trough the DA regardless of the speed i pulled the trigger or how much i concentrated on avoiding it. After this pass the sights no longer move unless i am slacking. Its still not as smooth as a well tuned 75 but it is getting there. With some use i believe that it may continue to smooth out. I bit of lube is not a bad idea ether.
 
   The DA was my biggest gripe with the P-09, i guess i have less to complain about. Even though it is not a 75 variant. In time me and this pistol might just become friends. Not good friends mind you, my 75s would not have that:) I also learned some things about the Omega trigger system. While i have much more to learn about the P-Series it is a step in the right direction.

If you are motivated to work on your own CZ P-Series pistol please take the time to review the guides produced by other forum members linked below. I have been over them many times and continue to benefit from them.

Great write up! I sold my P-09 some time ago and my wife's P-07 doesn't require any more polishing. That said, I enjoyed reading this, thanks!

Nice! I also have the 75 plus stand and used Schmeky's guide and Joe's videos to polish and install the Pro kit in my 09 and 07. I love the improved trigger and function in both firearms!

Added some things, fixed some spelling and grammar mistakes, not all of them, that is unlikely to ever happen.  ;D

Thanks guys, glad you enjoyed the read. May your CZs run flawlessly.

Interesting mods, Years ago, I thought nothing about total dissassembly of any gun, but lately, it seems to be a big undertaking.

This was great. Just ordered a p07 so I'm excited to get into it and make it smooth.

Nice post.  I have done these same things on two P-07's but didn't take the time to document it.  This should be a good reference, along with the existing tuning thread, for new owners looking to polish the internals of their P series.

Taking the time to position, record photos, sort through them, take the time to put them on a website that hosts pictures, putting them on the forum and explaining them takes way more time/effort than doing the mods to the pistol.

You put a lot of work into that.  It's appreciated.  Now you've got me wondering about doing that to my .40 S&W P09.

To echo what M1A4ME wrote, many thanks for the thread.

I bought a P-09 yesterday and spent a couple hours following this thread and Schmeky's step by step. I had been lusting over this pistol for a while, so I had all the bolt-ons at the ready.

I probably wayyy overdid it with the internal polishing, but working on a gun in the garage sure beat being on diaper duty inside the house haha...

Now to pump 500 rounds through this beauty to break her in a little :)

Hello, welcome to the forums.  I was wondering, which model number of Hogue Handall grip sleeve is that on your P-09?  I run the Handall "tactical" versions, after some trimming, on my P-07's, but yours looks like it has more coverage on the beaver tail.

It's #17020. Meant for the Glock 17.

Not quite a perfect fit, but close enough. And it adds some much-needed (IMHO) palm swell.

I had a HandAll Jr. on my P-07. Definitely took some elbow grease to get on, but I've always loved having Hogue grips on my guns.

I'll bet the 17050 fits nicely on the P-07.

A few hours spent following the polishing routine, combined with about $35 in reduced power springs from CGW (hammer spring, firing pin spring, trigger spring) and reducing tension on the trigger bar return spring has really taken my P07 to a whole new level. I would highly recommend doing this.

Hey tok,
 I highly recommend this for both po7 and p09.

^^Thank you for the link Doc. I like learning new tuning options. I will check my P-09 and proceed accordingly.

Has anyone tried to take machining marks off of the hammer where it engages the sear? I can really notice them when manually cocking the hammer. It would seem like this adds alot of grit to the pulls in single and double. Any advice without ordering new? I live in Canada, so parts availability and cost is amplified greatly.

Thanks
