I recently purchased a CZ 75B and love the gun. It is my first DA/SA handgun. As far as having the gun ready for operation, why not just have it cocked and locked instead of 'decocking' it manually with the hammer down on a round? Or when I decock it, am I supposed to put it in the half cocked position? It just seems a little risky every time I bring the hammer down on a live round.
