The biggest difference between the two is the action, as stated. The reason I don't have a CZ is the looong reach out to the trigger for my stubby little fingers, it just doesn't fit. Lots of folks have them and love them, but they don't fit my had so I don't shoot them. Try one on for size and see how you feel.
My everyday carry gun is a Hipower in .40. For carry purposes I really like the SFS system that Cylinder & Slide sold to FN, and I have it in my gun. With the SFS system you cock the gun, then push the hammer forward. This raises the thumb safety and locks the trigger and sear. When you draw the gun you swipe the thumb safety as normal, the hammer springs back and the trigger unlocks and the gun goes bang.
After removing the mag disconnect the trigger on my Hipower is as good as on my 1911, about 3.5 pounds and a very clean, crisp break. The gun is so flat and thin it's a pleasure to carry. The .40 version carries 10+1, it's a nice middle ground between a 9mm and a 1911.
CDNN still has some left at a great price, call them and see what their stock is. A year from now you'll be able to sell it for more than you paid for it, it's hard to lose at $400 for a real FN gun.
