I would suggest you take your pistol apart for a cleaning, and remove the firing pin and inspect it, and clean the firing pin chamber. When you re done, order a Harrington firing pin and install it. Post your results...and good luck. The CZ70s are nice shooters...see my "cz 70" post elsewhere in this dept.

I did that today soaked it and installed the Harrington pin yesterday
Firing pin dose not bind up   the problem is when its fired the hammer dosen't stay cocked
it fires like a automatic
The hammer returns with the slide even when operating it manually no finger on the trigger
something in there is not right i just don't know which part or parts to replace

Have been reading other post on the 70 and doing those checks and tests
and the darn thing still goes full auto is why am only loading 3 rounds at the most

Well got the parts today Installed them in gun  Hammer still follows slide closed  NUTS!!
When cycling by hand   When taking it apart i did see that the pin in the hammer was worn bad
Sooo i ordered one of those
I missed it when ordering other parts or would have gotten it then
If that pin don't fix it I don't know what else to do to it
I will post what happens
