I believe another poster had the same issue about 2 months ago with a Rami. You might SEARCH for that thread.
CZs generally prefer rounded nose ogive ammo, and so I lean toward using Gold Dots which have never given me any issues in a P01, SP01, or P10.
CZs have always needed a break-in period. All I can suggest is to lube with 1 drop of 5W20 synthetic car oil on both rails and the barrel bushing.
Hope this helps.
