ČZ-52 Safety Notes

The basic laws of firearms safety

  1. A gun is always loaded.
  2. If you believe that the gun is unloaded, see the first law.
  3. Never point the gun at anything you do not wish to shoot.
  4. Never put your finger on the trigger until you are ready to engage the target.
  5. Know your target and what is beyond.

Safety / decocker operation and safety issues

The ČZ-52 safety has 3 settings:

ČZ-52 pistol, safety in safe position.

Safety in Safe position.
However, see the discussion below!

ČZ-52 pistol, safety in fire position.

Safety in Fire position.
Be careful, the weapon is ready to fire!

However, that is only the intent of the design.  If the decocking notch is worn, the motion of the decocker may raise the firing pin detent and that has the same effect as pulling the trigger in the "Fire" position! 

Think carefully about that phrase "If the decocking notch is worn". This is a surplus weapon built in the early 1950s and possibly with much use before you bought it. The only safe assumption is that it is worn!

Do not rely on the decocking mechanism to safely decock the ČZ-52. If your decocking notch is worn, and it probably is, your pistol will likely fire when decocked.

The original ČZ-52 design included a rather ineffective firing pin block that becomes less trustworthy with wear. As stated above, all ČZ-52s are old and most have seen significant use use. The safety disables the trigger, but if the gun were dropped there is a chance that the hammer could fall and strike the firing pin.  The ČZ-52 should not be carried with a round in the chamber. 

Here is what has come to be known as the "pencil test" of a ČZ-52 decocker. It can warn you if your decocker is defective:

Put a pencil into the barrel, eraser-end first. Activate the decocker.  If the pencil moves at all, the decocker is basically a trigger!
