If the CZ bothers you, Walthers will probably scare you to death!
A friend of mine got a Walther PP Super Ultra, 9x18 Ultra. This was a commercial gun imported for sale, not a police trade in. He had the gun for several years and then discovered a serious problem.
My friend has rather small hands, and could not easily reach the safety to decock the gun with the pistol in the usual upright shooting grip. SO, what he would do is lay the gun on its side, which allowed him to reach the lever. He did that for several years, no issues.
THEN, one time he was out shooting with a friend, who asked to try the gun. This fellow was larger with larger hands, and when he applied the safety to decock the gun with the gun held upright in the usual way, THE GUN FIRED!!!
They tried it one more time, and the result was the same, with the gun held normally, decocking it FIRED the gun!!!
They took it to the gunsmith, he was astounded. There were broken parts, which, if the gun was held sideways, lined up and worked properly, but with the gun held upright, did not, and allowed the gun to fire when the safety was put on!!
I mention this, not as a bash against Walther, but just to illustrate the fact that the most unthinkable things ARE POSSIBLE, even if extremely rare, and that ANY system CAN fail. They rarely do, but they can. Never put 100% trust in any mechanical safety system!
Proper safe gunhandling (particularly muzzle control) ALWAYS, ALWAYS MATTERS.
Some designs drop the hammer down to a safety notch and it never hits the firing pin. Other systems lock the firing pin and let the hammer hit it. And there is at least one system that places a block between the hammer and the pin and lets the hammer hit that.
No matter what the design is, ALWAYS point the gun in a safe direction when decocking. ALWAYS!!!
