Anyone know where I can purchase a stock firing pin for a Shadow 2? I'm having trouble finding one.
-
It's the same firing pin like in SP01 Shadow.

Honestly, I'd look at getting the extended version and reduced power hammer spring to reduce the DA trigger pull weight.
CGW sells his ultralite kit:

CZ Custom has both the stock length and extended length firing pins:

https://czcustom.com/cz-parts-all/fire-control/cz-85c-ts-shadow-extended-firing-pin.html
Pick your poison.
Cheers,

Thanks. I didn't realize the stock length would fit the Shadow 2 since it isn't listed in the description. Comparing the description of the extended firing pin and the stock firing pin I see now that it would fit.
Does anyone know the length of the CZ Custom extended firing pin? I currently have the CZ Custom extended firing pin in my Accushadow 2 and it extends past the breech face with the hammer down. My Accushadow 2 has a 13 pound hammer spring and I read that the stock firing pin should work fine with a 13 pound hammer spring. I'm considering trying the stock firing pin to see if it's reliable.

CZ Custom emailed me the length of the CZC extended firing pin and stock firing pin.
CZC extended firing pin 63.63 mm (2.505 inches)
Stock firing pin 62.67 mm (2.467 inches)
I plan on ordering the stock firing pin to see if it can reliably ignite my Winchester primers using the Rami firing pin spring and 13 pound hammer spring.

I received my stock firing pin from CZ Custom today and installed it in my Accushadow 2. Removing the extended pin was easy but getting the new stock pin in was difficult. Holding the firing pin down against the spring while sliding in the firing pin stop was a challenge.
With the extended firing pin, holding the gun vertical at waist height the gun would "shoot" a pencil and pretty forcefully hit an 8 foot ceiling.
With the stock firing pin, holding the gun vertical at waist height the gun would "shoot" a pencil and hit an 8 foot ceiling, but with less force than when the extended firing pin was being used.
I'll be going to the range in a couple of weeks and I'll test the new stock firing pin with both Winchester and CCI primers. My Accushadow 2 has 13# hammer springs for reference. I'll report back what my results are.

Thank you for sharing your experience with the stock firing pin from CZ Custom for your Accushadow 2.
When you have the chance, please do share your range report and the results you observe during your shooting sessions.

Using my Accushadow 2 with a 13 pound hammer spring, stock firing pin, and Rami firing pin spring I shot 100 rounds using Winchester primers and 100 rounds using CCI primers. I had no failures or malfunctions of any kind. The indentation in the primers was not as deep as when I was using the extended firing pin but still pretty deep. I'm going to shoot another 100 rounds using CCI primers next weekend and if I don't have any issues I plan on competing using the stock firing pin in my Accushadow 2.
-
I'm curious why you are taking out the extended pin?
Cheers,

The extended firing pin extends past the breech face when the hammer is fully down. The starting condition for USPSA Production division is with the hammer fully down. In this starting condition the extended firing pin is resting against the primer of the loaded round and the hammer is not resting against the slide. If the gun were to fall on the hammer an accidental discharge could result. There are several videos on YouTube demonstrating that a Shadow 2 with an extended firing pin will fire when a hammer that is fully down is hit.
The stock firing pin does not extend past the breech face when the hammer is fully down. When in the USPSA Production division starting condition the hammer is resting against the slide and the firing pin is not touching the primer of the loaded round. It is not possible to have an accidental discharge in this starting condition. If the gun will function with a stock firing pin there is no reason to assume the inherent risk of the extended firing pin. From the research I've done and the results I've obtained so far, there is no reason to use an extended firing pin with a 13 pound hammer spring and Rami firing pin spring. I kept the extended firing pin and can go back to it if I start getting a lot of failure to fires, but so far there is no reason to take on that risk.

Yes that has been proven to be an issue if the gun is dropped.
It is one of the rules in USPSA that I want changed. Regardless of the type of action, if there is a half cock position for a hammer fired pistol, you should be able to use it in the hammer down start position.
What they really should do is let you start locked and cocked if there is a safety. If there isn't, you should have to start decocked. The rule should state that the gun start condition should be the safest condition (if multiple conditions are possible) and then define the safest conditions in the glossary.
Cheers,
Toby

I shot another 100 rounds using CCI primers. No malfunctions whatsoever. The gun worked great. I plan on shooting another 150 rounds (450 rounds total) and then start using it in USPSA competition. I'll feel better knowing the gun is drop-safe.
