Why safety only levers for the Shadow 2 models?

[Metal Wonder Nine Guy]

I think that for some competitions the user has to start hammer down. If that's the case, then wouldn't a decocking lever be better than a safety only lever?

I'm still learning about the different styles of competition, so forgive me for the silly questions.

IIRC, the Start condition for USPSA limited, open and carry optic classes should be hammer cocked and safety on. Only in Production class would it have to have the hammer let down. (Shadow 2 isn't legal in IDPA without taking weight off, so that's not a relevant game.)

[Sancho]

It may be a different logic entirely.

I had sent a P-01 off to a well-known custom shop.
They removed the decocker and installed a normal safety.
When questioned, I was informed that the trigger assembly for a safety has fewer moving parts and is easier to tune than a decocker.  If I understood correctly, then installing a safety in the Shadow 2 makes sense.

For USPSA so Carry Optics and Production divisions, it has to be hammer down for DA/SA pistols. Single action pistols are not legal in Production and Carry Optics. Only DA/SA and striker fired guns are allowed for both division.

In limited and open (if you decide to use it in open), you can start either hammer down or cocked and locked with the safety on.

I use my weak hand thumb in lowering down the hammer on my shadow 2  while squeezing the trigger slowly with my trigger finger when competing in USPSA. In fact, I already got used to doing it that I do the same when I’m doing live fire exercises.

Yep, keep the decockers off of my CZs!

I'm not scared to manually lower a hammer.  Competition shooters do it constantly.

All factory decocker CZ pistols have a firing pin block safety.

Shadow 2 pistols don't have a firing pin block safety.

Shadow 2 pistols don't have a firing pin block safety.

Why is that? Less linkages that don't  adversely affect the trigger pull?

So what are the argument for/against removing the plunger and spring (ie. SP01) for competition?

It is illegal against the rules to remove a safety device. 

If it never had it in the first place, no problem being without it!

   The most significant differences would be the pistol without the Firing Pin Block having a shorter Single Action reset distance. The CZ 75 variant FPB design requires a bit more trigger travel to function. In a CZ B model (FPB pistol) two tings need to reset, the sear and the FPB Lifter Arm. As you let the trigger out in SA the Sear resets first then the FPB resets a bit further out. In a Shadow (non FPB pistol) only the sear needs to reset because the Lifter Arm is removed from the equation. Clarification: In a CZ B model (FPB pistol) during normal function there is only one real reset, the presence of the FPB Lifter moves the reset point further forward as you let the trigger out in SA. The Sear reset is passed over and the pistol resets at the FPB lifter instead. After the pistol resets and you pull the trigger in SA, as the trigger moves rearward the Trigger Bar picks up the FPB Lifter fist then the Sear and actuates both of them as you pull through the SA to drop the hammer.

   So you can tune and polish and tweak a CZ B model and make the FPB parts almost unnoticeable while pulling the trigger but you can not obtain the absolute minimum reset distance with the FPB intact. Having a minimum reset distance then allows you to minimize the SA pre-travel with an oversized disconector.

   With a CZ decocker in which the FPB must be left intact the SA reset distance can not be reduced to the same point. A short reset kit will get you half way there but the other half requires a non FPB pistol.

Thank you for the explanation.  That explains the shorter reset in the Shadow pistols I have.

Excellent explaination!

You had this done with the regular P-01, not the Omega?  Which shop?  I didn't know that this modification was a thing.

Keep in mind that for USPSA Production and Carry Optics divisions, where DA is the required start position, you have to have the hammer all the way down. Not in the half cock position. So even with a decocker, you will have to manually decock the hammer.

That is not correct.  USPSA allows you to use the decocker.  The hammer only needs to go down all the way for safety-equipped guns.
