I have heard that the CZ75 BD 9mm can be made to also fire 22lr. Is that any CZ 75 BD including the polic version? I asked the ld but he had know idea and I am just learning about hand guns myself. I really like the CZ75 that I have been looking at and think that it would be great if I would have the flexibility to change it to a 22lr also. Thanks in advance for any info you can provide.
