Reply | Edit | Del All CZ70 Bouble action trouble
--------------------------------------------------------------------------------
I have a CZ70 that doesn't work in double action but functions fine in single action that has been sitting in my safe forever. I guess that is why it looked so good from the importer, the only use it got was when someone was trying to figure out why it wasn't working (it would also explain the nut on the hammer pivot being so worn) I was going to take it all apart (push out the pins and so-on) and see if I could make sense of it. It seems to work double-action when the slid is off, or the main spring (for the hammer) is removed. I'm guessing
Something is slightly tweaked down in the frame. Has anyone had the same problem, and does anyone know how to fix it? I am also looking for a parts supplier and an exploded view of the gun.
Thanks

I have a CZ-50, which is almost the same gun, but the DA works fine. I took a look, and it's not obvious what might be wrong with your gun without looking at the gun itself. Sorry I can't be more help...

Explain "doesnt work in double-action." Does the trigger pull to the rear or no?

--------------------------------------------------------------------------------
Well, I hope I didn’t wait to long to respond but here's the problem:
The transfer bar doesn’t' engage the hammer for some reason. So, the trigger goes to the rear and the only thing that happens is that the sear drops (but, since the hammer is already forward, this is
Pretty useless...)

I dont have a schematic on that gun in front of me (I'll find one), but may of those type DA's have a spring that holds the transfer bar up in place. Will the gun cycle DA if you turn it upside down?

That seemed to be the nature of the problem: a weak spring. When I had the slide and grips off, I could make the double action work or not work by applying a light force on the transfer bar. It seemed like there was a spring that was weak or out of place at one end.

So what was the issue? I pulled my CZ 70 apart to stone the trigger and sear and upon reassembly I'm having the same problem with the transfer bar not staying in position to contact the hammer/sear. It will held upside down, so it appears that something holds it in position like a spring. I have a schematic but I see nothing on it. Please help if you have suggestions.
