I have a CZ 100 in 40S&W and it is my carry piece. As others here have indicated, the trigger is nothing to write home about, but there are a few tweaks that can be done to make the trigger pull bearable.
Trigger notwithstanding, the ergonomics are incredible and, as with most other CZ pistols, accuracy is very, very good. Out of the box, the CZ 100 suffers from having a rather weak recoil spring which makes for very harsh recoil when shooting factory loads, but this is easily rectified by replacing the spring with an aftermarket one intended for a compact Glock (it's a drop-in fit for the CZ 100). I have a 24 lb. recoil spring in my CZ 100, and recoil is not an issue with that.
