Title: CZ50/70 trigger spring
Post by: Jmq4 on September 21, 2014, 08:07:44 PM

I have a CZ70 that came in pieces and without a trigger return spring.  I have looked everywhere but cant find one.  Does anyone have a spare that would be willing to part with?  Alternatively, could someone take a picture of one with dimensions so i could make one?  I tried a CZ52 spring but it doesnt work correctly

Thanks

Joe

I'm not anywhere near mine at the moment, but here it is.  Part 29:

I found some schematics that show the trigger spring at scale and also a source for new, but very expensive.

Thanks to all.

Any chance you could share those schematics and the source for new springs ?  I have a cz70 i am assembling from parts also and am missing the trigger spring #29 from the parts diagram.  My direct email is aschwabe (at) gmail (dot) com

thanks!

Numrich has the schematics but they appear to be sold out of the Trigger Return Spring.  https://www.gunpartscorp.com/Manufacturers/CZ-33195/AutoPistols-35899/70-34929.htm (https://www.gunpartscorp.com/Manufacturers/CZ-33195/AutoPistols-35899/70-34929.htm)

Looks like most every place is sold out of that spring.  Hmm...

Most of us believe that the CZ50/70 was based off of the Walther PP (PP, PPK, PPKS) series of handguns.  The trigger return spring for the PPK looks really close and if you trimmed off the "U" loop on the bottom, it might be made to fit and work.

Here's a Czech language (I think) schematic:
