    CZ21 mod

    Can the toggle switch modification that can be done to the Excall also be done to the CZ21?

    Yes, I bought two cz's several years ago in hope of having the time to do them. I did break one down to look and it is possible. Unfortunately I focused only on the Excalibur and sold both of the Cz20's. I do have a video on how to break down the CZ if your interested.

    Effort is Important, But knowing where, can make all the difference!

    I know how to break one down. I have never been able to get one to work again though. What is your secret?

    I would love to see the video also.
    Please leave a ring after the beep. Thank You.

    I have seen a lot of guys try to take them apart but could never get them back to normal

    CZ21 panel is different then the CZ20. The CZ21 can't be opened without replacing the entire front panel (my understanding from Fisher) because I *think* it's glued rather than using a gasket.

    Not 100% positive but that's what I was told.

    I doubt it. I am sure it has a gasket and the 4 screws are in the battery compartment. I don't think First Texas wants you trying it.

    It does but what I was told is that once the seal is broken on the face plate, it can't be repaired without replacing the faceplate. When my friend sent his in for repair the charges included a new face plate (which is what lead to the question). I'd like to know if this is true or not. Surely someone has taken one apart here?

    I'm not sure what Fisher told you, but it may have been that what they meant to convey was that they won't repair a CZ20. If one is sent in, it will me returned as a CZ-21 which mainly means it gets a CZ-21 front plate.

    He sent in a CZ21. I found this image which proves otherwise though:

    Check this out...seemed like he should have pulled the standoffs thru so he wouldn't need to remove the sticky face plate.

    Unless there are no aluminum standoffs in the CZ21 like the CZ20, but that seems unlikely.
