could some elaborate or point me in a thread direction ..

I wanna make sure I keep my baby pristine ! 👍😊

High volume dry fire seams to be more of an issue. From my experience a replacement Firing Pin Retaining Pin is a cheep and worth while upgrade. They are rather straight forward to install and they fair much better than the CZ factory FPRP. For low volume dry firing this is sufficient in my opinion.

For clarity, the issue at hand is the potential damage to the factory FPRP. The FP can be driven into this pin repeatedly and cause issues over time. During dry fire and even during normal live fire use in some cases this pin can take cumulative damage until it breaks and in some cases falls out of the slide. The CGW replacement pin is of an improve design and material. In part it acts like a spring to absorb the energy of the hammer

I also use an O-ring for any significant dry firing. When placed behind the FP it stops or decreases the force transferred into the FP. A snap cap is another viable option. The down side that i have found with snap caps is that they break down over time and they are not as effective as an O ring. Some folks even place a disposable foam earplug behind the FP, i have no issue with this option.

If the pistol is for Self defense just remember to take the O ring out after a dry firing session.

Here are some reference pictures. Any O ring close to this size and thickness will work fine.

This is interesting...would it be different with the comp specific Shadows? There are people in my club (who are Master grade looking to get on the National team etc) who are dry firing a couple of hours every day and I've never heard of anyone using an O ring.

 yes, as the shadow does not have a firing pin block, which is the issue!

   Indeed, there is no Firing Pin Retaining Pin in a CZ Shadow, CZ 85 Combat or the Pre-B CZ pistols. In non FPB CZ pistols the Firing Pin is retained by a locking plate at the rear of the slide. To my knowledge they are much like a 1911 in this regard. The Firing Pins of Non FPB CZs are also diffident in that they lack the cut out for the FPRP among other things. The forward movement of the FP in a non FPB CZ is stopped by a shelf inside the FP channel rather then the FPRP in a CZ with an FPB.

   One way to quickly differentiate a factory CZ with a FPB from one without a FPB is to look for the FPRP hole in the slide. If there is no hole it dose not have a FPB.

Here is a reference picture of the FPRP hole.

I bought these little things that's supposed to be incorporated randomly in magazine to simulate a malfunction and use 'tap-rack-bang'. I'm not that far along in my practicing yet though. But, currently I keep one in chamber, cock hammer and dry fire practice. If I dont have one in chamber I usually just dry fire my P09 anyway. Probably not the best thing to do. I need to get one of the 'o rings'.....neat trick.

Thanks, Tok36, for link to FPRP link. I need to get me a spare one. One thing I read when I viewed the installation notes is to keep FPRP in the 12 O'clock position when re-installing. Oops....missed that important bit of info. No wonder mine is a major pain to hammer back in.

Here's a cool vid I found on malfunction clearing
