That's odd. I don't have a CZ, and I had not heard of the aforementioned problems.
I do have a CZ clone though, and it's chambered in .40S&W. It is a steel framed, full-size IWI "Baby Eagle" and I've not had the first issue with feeding problems.
The only problem I have is keeping enough ammo to keep it fed.
A little reading on czforums and you will hear of it. The RAMI P was dropped due to frame swelling issues. Similar problems along with cracking and reliability issues with early P-07s. There for awhile CZ couldn't build a pistol in 40 and have it run right. All of which has been fixed now though.
