I owned a TZ75 about 25yrs ago (before the EAA Witness changeover) and it was a nice shooting little pistol. I had the 4" model, which was handy, and carried it cocked and locked. I even used it to shoot some IPSC and plate matches when I was in High School. I did observe that it did NOT like the cheap Blaser aluminum-cased ammo, but fed pretty much everything else fine.
All of these pistols: the TZ, CZ, EAA, and even the Springfield P9 were all essentially "copies" of the Hi Power frame, which is a VERY ergonomically pleasing grip frame to a lot of shooters. The XDs feel better than Glocks to many shooters because some of the same grip ergonomics were worked into it.
