Hi and welcome to the Forum. I hope you will enjoy your stay with us. We have great members and lots of folks that want to help other members learn about their CZ's.
I don't know if you got an answer to your e-mail to CZ-USA but I sent them an e-mail myself and I just received this answer, and I quote:"There are no English versions of the holster manuals. If he is having trouble with the holster, I would suggest he call 1-800-955-4486 ext. 335 for assistance". Go figure
In all the years I have owned CZ's, about 35, and in the last couple years times I have actually spoken with them I have never seen or been given an answer that just cracked me up completly and totally as this one did. I almost fell out of my chair. I also know this isn't funny to you at all probably, but there's your answer. At least it's a free call.
Honest, no one could make that up, and I am really sorry I can't be of any help to you. At least not in this matter anyway.
