Two CZ75B questions

I have seen so many good press about the CZ75 that I went and bought a CZ75B two weeks ago and so far I like it a lot. However, I do have two questions:
1) How do you remove the firng pin for cleaning? The manual only describes the procedure for the CZ75 (that has a firing pin stop) and mentions that those models with a firing pin block (ie the CZ75B) be clean by a gunsmith. I am mechanically inclined and I am wondering if the experts on this forum can share you experience..
2) Mine is the regular DA/SA model and the manual describes decocking as pulling the trigger while holding the hammer and then easing it onto the firing pin stop. However, isn't there a hammer half-stop which is used by the CZ75BD models? Why not stop at the half-stop also for the regular DA/SA models?
 
according to the manual the CZ75b has:
Safety Stop on the Hammer - A half-cock safety notch is on the hammer so as to prevent it from
striking the firing pin when the hammer is manually cocked, and a thumb could slip. When the
hammer is on the safety stop, it is not leaning against the firing pin stop, but its position is further
back.

the manual & diagrams are here: http://www.czub.cz/PISTOLa.HTM

I'm wondering the same thing. As I understand it you need to be a trained CZ smith to get the pin out. That's one reason I favor the CZ75.

The CZ75B also have a half cock, at least the ones I've examined. Pull the hammer back and you'll notice there's an intermediate position between full cock and rest. The half cock functioned as a safety on the CZ75, it wasn't there on the earliest CZ75s. I met a couple of people that carried their CZ75s in the half cock, claiming it was faster than DA and cocked and locked.

Yes my CZ75B does have the safety notch and my question is that with the 75BD, when you use the decocking lever, the hammer will end up resting at this safety notch. This is fine and I can do the same to my CZ75B when I manually decock. However, this is not what the manual is suggesting - release the hammer all the way (ie go past the safety notch) and let the hammer rest on the firing pin stop. In a way, this is confusing on its own as the parts diagram for the 75B does NOT have a firing pin stop?

That's the way I shot my CZ-85 Combat in IDPA competition. I'm not sure its faster, but it does give a lighter trigger pull (and virtually no DA/SA transition problem), and its slightly less difficult, since you don't have to worry about flicking the safety off.
 
I want to know how to remove that firing pin too !!! I just got a Wilson's spring replacement kit for the CZ 75 ($13 at CheaperThanDirt.com) and I want to replace the firing pin spring.
 
Getting the pin out of a "B" looks pretty straight foreward, just drift out the firing pin stop pin and it should pop out the back of the slide. The firing pin block stop and spring are offset and sprung away from the pin so they shouldn`t interfere. Now,who has the guts to try it (not me!). :D Marcus
 
Marcus,
I have been visualing the procedure before I put up this post and it would be similar to what you have described except for one thing - since the Firing Pin Block Stop will get pushed up just prior to firing, my understanding is that it will block the firing pin movement in its normal (ie downwards) postion. In other words, I think the Firing Pin Block Stop needs to be pushed up in order for the firing pin to be set free. This is perhaps a tricky step as one has to ensure that the firing pin doesn't fly out and either gets lost or causing injury.
Someone on this board must be able to confirm/deny this?
 
It sounds similar to the CZ-52 setup, with the addition of the roll pin through the slide.

1) drift the roll pin most of the way out of the slide.

2) depress the firing pin safety to release the firing pin.

It should simply slide out at this point. After looking at the schematic, that's exactly how it should be done. Not a big deal.
 
Looking at the CZ75 spare parts diagram got me thinking ... Since the firing pin roll pin and the firing pin block stop sit in their respective notches (of the firing pin), won't they get hammered each time the trigger is pulled? Or are the 2 notches big/long enough to allow free forward/backward movement of the firing pin without any impact to the 2 parts?

The region the firing pin is engaged by the roll pin is simply slotted to allow free travel.

The area that the firing pin safety engages should be slightly deeper at one end of the slot to lock the pin in place when the trigger is forward.
 
Regarding the firing pin block stop...I would think that the pressure of the firing pin block stop spring would push the block down and blocking the firing pin travel. Not sure if the slot would need to be deeper to achieve this...
 
Here are some firing pin and firing pin safety details:

As you may see, the firing pin safety works sort of like the magazine release on most pistols: when depressed, the pin is free to move; when released, it is not.
