As common as conversion barrels are to convert a .40 Glock to run 9mm, I don't imagine we'll ever see that in the CZ world. I don't think that there's a big enough market to make it worthwhile for a barrel maker to do that. In the Glock world, there are lots of police turn in .40s around to make a conversion more useful, but even then, the numbers of Glocks running conversion barrels is small. Given the rarity of .40 CZs, especially the total lack of .40 P10Cs, I don't think we will ever get the conversion barrels built for CZs.
