CZ-70 Double Action not working
« on: July 09, 2019, 06:07:50 PM »
Hi, I'm facing a problem with my CZ-70 Handgun which is the Double Action mechanism is not working at all.
So, when I decock the pistol and pull the trigger, no thing is happening, feels only emptiness.
I hope everything is clear.
Thank You!

The same exact problem is here in the video.
Remember: the pistol in the video isn't mine and not the same. Only the same problem that I'm facing.

Mr.DOC1500,
Thank you for helping but my problem is very different from the one in that thread.
My problem is the Double Action does not work at all. When I decock the pistol and pull the trigger there is no action from the hammer. I hope it’s clear. And I’m waiting for someone to help me.
Thanks.

the back of the trigger bar, hooks on a small little thumb of the base of the hammer I believe that is how the double action works.  if it is on safety after using the decocker, you can not pull the trigger, the safety is blocking the trigger bar.  if not on safe, there is a curve on the back of the trigger bar, that hooks a notch in the base of the hammer, and that is what pulls the trigger back.

If you know how to take the side plate off, you should be able to see the things that happen in there.  possibly, the hammer nut is just loose so the trigger bar is not grabbing the hammer correctly?  also, you can see how the safety works with the side plate off, maybe it is not rotating to the correct position or something.
