When I joined the forum some time ago, there was a discussion on a "pin" for the CZ 75 B/BD that was prone to failure and a recommended source for a hardened pin. I cannot for the life of me remember any more than that. My CZ 75BD is fine, no issues but have given thought to having a spare part or two around the house just in case. Can someone shed some light on this for me? I tried searching but no luck. Thanks.

Was it the firing pin retaining pin from CGW?

I don't have a CZ 75BD, but most likely it's the firing pin retaining pin. Dry firing a lot can damage it. An o-ring or foam ear plug squeezed in front of the hammer is a great preventative measure.
If you want a hardened pin, then CGW has a great one.

It may have been the firing pin retaining pin. I truly cannot remember. I do remember there being several problems brought up in the same group of posts including a 'rolled' pin, a firing pin, and a spring. But they seemed to be unrelated. I will check out cajun gun works. Thanks folks.

Cajun sells a tool steel firing pin along with the NON roll pin style firing pin retaining pin linked above. The kit also includes a lighter firing pin spring.
You might buy a spare slide stop as well. They can break eventually.

The firing pin retaining pin is that rolled pin. You can always take out this pin and inspect it for wear.

Patriot Defense in Kemah, Texas and BH Spring Solutions have parts selection too.

Trigger return springs break occasionally too. I run the cajun firing pin retaining pin and a rami firing pin spring, it's a bit lighter than the standard cz's.

Just buy several of each, they're cheap - the steel retaining pin and the TRS from CGW. The CGW retaining pin is much easier to put in/take out and makes swapping the TRS a breeze. I haven't broken either stock part, but I went ahead and replaced them both proactively as I neared a 1000 rounds on my PCR and SP-01.

As most of us CZ fans know to use an o-ring for dry fire, I do not see the FPRP as an issue (especially after replacing with a CGW one). What I do keep reading about is trigger return spring failures. Most seem to be OEM, but then I see people stating that the CGW ones fail as well. I keep reading that the CZ is much more prone to have this failure than other DA/SA handguns. Not sure how true this is.
Also the slide stop is another failure point I read about. I see this as a wear item and would think that replacing at a certain round count would prevent this. I even read people saying that these two things are design flaws and would prevent them from ever using a CZ for serious use like defense and/or duty. The stuff I was reading had me worried for a while. However, I then read about Mike Pannone's P09 and P07 running fine with very high round counts. Plus all the militaries and police forces around the world that have used CZ handguns for decades.

I had to replace the FPRP after 5k laser and 700 live rounds. The RP was broken causing the FP not to strike the primer. I replaced the RP with MCARBO FPRP and just recently checked it after around roughly 2K tigger squeezes combo of laser/live rounds and it had a very light shine mark on it (no biggie). I plan on checking it after 4k trigger pulls (combo of laser/live rounds).

Good thread.

I'm no expert, just own, shoot, clean and lube several CZ pistols.
The FPRP wear damage is variable on variable pistols. I've pulled factory FPRP out of brand new pistols to replace them with the CGW pins and found damage. So a new pistol, fired only at the factory (how ever many times they fire one for testing/adjustments) shows damage to that pin. I don't know if it's just live ammo fired or if they also dry fire them.
On the other hand, I've pulled the factory FPRPs out of pistol I've shot for years and dry fired now and then (with no O-ring or snap cap) and seen less damage to the pin than on some new pistols.
What is called anecdotal evidence is related here on the forum by multiple members about the slide locks. Some guys get 20,000 rounds through a pistol with no breakage. Others break one in less than 5,000 rounds.
Different guns are different.
It's still a good idea to have some spare parts. You won't know if your gun will suffer from a broken slide lock, broken trigger return spring, broken firing pin retaining pin, etc. until it happens.
I've got a couple of those divider style tackle boxes with CZ pistol parts in them. Some day I might need to use a part, or two. At this point I'm figuring I'll probably have to let my boys sit down and divide them up after I die.

Sound advice, and you're the type of person I'd listen to before an "expert" :) thank you for your input.
