CZ does not recommend using non-brass ammo. If you continue to have FTF issues, send it back to the factory and they will lengthen the chamber throat, like they did to my Omega, which had the same issue.
Just curious where CZ has said not to use non-brass ammo in their pistols?
Per the Warranty Dept correspondence Technical Support and Gunsmith

"Aluminum cases are not recommended as it does not have the same expansion and contraction properties as brass and will cause reduced performance in a straight walled chambering, regardless of the coating or plating.
Our pistols are exclusively designed around the use of brass cartridges, so we can only recommend factory loaded quality brass cased ammunition."
"We cannot recommend the use of steel cased ammunition in our pistols, as the steel to steel contact will cause excessive wear to contacted parts such as the barrel, slide, and extractor.
This will require much faster replacement of these parts so while in the short term the cost is slightly cheaper for the ammunition, the later replacement of these parts or even pistol would outweigh any savings.
For this reason, we can only recommend quality factory brass cased ammunition for the best function and longevity."
