Here's a link to CZ's site with some of the info you need. Looks like there are tritium sights from CZ available, and the pistol is SA/DA, with no decocker (version with decocker is available if you look at their compact pistol page).
If it's designed like the CZ-82, I would also expect that there is an ambidextrous thumb safety which can only be engaged when the hammer is back. The intended method of safe-ing the pistol is let the hammer down carefully on a loaded chamber and to rely on the long DA pull to prevent negligent discharges, so the thumb safety tends to only be used for temporary cease fires. At least for the CZ-82, the manufacturer does not recommend "cocked and locked" carry with the thumb safety on.
Hope this helps! Let me know how you like the 75 compact, I'm keeping an eye on it for when I've saved enough to upgrade from my 82.
