IOW, can the 9mm be fitted with a .40 top end, or vice versa? I know about the .22 kit, but are different top ends even sold for the CZs, like EAA does for the Witness?
You know I don't know if they are but I don't think so. You can check out the http://www.cz-usa.com for the importer's web page. I don't think they sell any kits like EAA's. By the way I just talked to the gunsmith at CZ-USA and he told me the .22 convesion kit DOES work with the PCR model.. Another person there had told me they did not work because of the decocker..but the gunsmith said they do...hmmm i'm thinking about a PCR now.
