I ordered this exact same holster (plain black), and I am VERY impressed with the fit and finish:
https://www.concealmentexpress.com/collections/cz-iwb-kydex-holsters/products/cz-p10-f-owb-kydex-paddle-holsterI ordered a similar one from them for my Beretta PX4 a while back, and it was a bit looser and sloppier. This new one seems more refined and better built and has a slightly different paddle. Perhaps they made some changes? Regardless, the one for my P10F is fantastic and I just today ordered a similar one for my VP9, as I was that pleased.
UPDATE 2/1/2021: I contacted Concealment Express last week about the PX4 holster and they sent me a replacement one free of charge, and it is a much better fit. Looks like they upped their QC. As well, since this post I ordered another paddle holster from them yet this one was for my P320 Carry with a manual safety, and it too fits really well. I'm pretty much sold on the Concealment Express paddle holsters as my preferred "range holster" option.
