High Noon Holsters, of course, does excellent work, and carries plenty of holsters in stock that fit CZ handguns, the P-01 included. I just received an Under Armour from them that so far i absolutely love.
For Uncle Mike's, their Size 15 fits the P-01 near perfectly, however the trigger guard likes to hang on the soft floppy holster (at least in their on-the-belt model), and tends to take some wiggling to get it to seat without snagging and mooshing.
