Na I suppose this is a good place to ask that since we presently don't have a topic for that. Actually not much going on with the entire Longgun boards, seems weird but if the pistols are hard to get US folks to use, I'm guessing it must be a bear to get them to use CZ longguns of any sort. But what I know about Longguns you could engrave on the pointy end of a pin.
So even though I am of no help to you in this instance I would like to say Welcome to the Forum, and despite the lack of replies to your question here, we do have a really Great bunch of folks here and they/we try our best to help each other with ideas, suggestions or questions. So if I have already Welcomed you then consider this another Welcome and again sorry but I have no answer to your question.
