Shay1911 Posted August 28, 2008 Share Posted August 28, 2008 The gun is a CZ Champion, 9mm major. CZ is no longer importing this gun and CZUSA no longer carries recoil springs for it. The original recoil spring is a twisted wire spring, which does not exist in any other CZ. The gun has a full length solid guide rod and a reverse collar. A normal CZ recoil spring is 5", but with the reverse collar, in order for the gun to lock back, it has to be cut down to 3". The original spring is a twisted wire, which allows a full length spring to compress much further and, therefore, work with that guide rod. I have two springs, 14lbs and 11lbs at full length. I cut the 14, installed it and the gun felt over gassed, as in muzzle was dipping down, maybe the spring was too strong. The 11 feels a bit stronger than the original spring (that broke), but much better than the 14lbs. My dilemma is whether an 11lb spring that is cut would be sufficient. From what I understand, a spring's "power" is constant and the length should not matter. Is that right? Does anyone know of a twisted wire spring that I can use? I am assuming I would need around 9lbs spring. Link to comment Share on other sites More sharing options...
wide45 Posted August 28, 2008 Share Posted August 28, 2008 The gun has a full length solid guide rod and a reverse collar.

Can you use the spring system from a regular CZ? Link to comment Share on other sites More sharing options...
Shay1911 Posted August 29, 2008 Author Share Posted August 29, 2008 I wish I could find a twisted wire spring in 9lbs or so. Know of any? The problem is the fully compressed length of the spring. A full length CZ spring does not allow the slide to lock back. Link to comment Share on other sites More sharing options...
Jeff686 Posted August 29, 2008 Share Posted August 29, 2008 Some ideas: Write CZ directly. They might be willing to send you springs. Shipping international is not rocket science. http://www.czub.cz/ Post a request on the IPSC forums, asking for someone to buy you a few springs in Europe, and ship them to you. http://ipsc.invisionzone.com/ Ask Angus Hobdell. He might be able to special order some, or carry some back from a trip to Europe. Link to comment Share on other sites More sharing options...
eerw Posted August 29, 2008 Share Posted August 29, 2008 I thought the 40P or one of the SA 40s had a braided wire recoil spring?? any chance you can change or modify the slide/comp to accept another recoil system?? use the sprinco system with a short recoil spring?? can you post photos of the gun apart?? see what that reverse collar looks like??

Neomet Posted August 29, 2008 Share Posted August 29, 2008 Check with Angus at Ghost Products in Mesa, AZ. He shoots one at steel matches. Shoots it damn fast too. :surprise: Link to comment Share on other sites More sharing options...

Shoots it damn fast too. :surprise: Sig factory springs are a twisted coil design, maybe one of those can be adapted... Link to comment Share on other sites More sharing options...
Carlos Posted February 5, 2009 Share Posted February 5, 2009 Think that is right, though I'd have to dig some guns out of the safe to check - think you want the OEM spring from a 40B (aka Colt Z-40) or possibly from a .40 cal 85 Compact (think they changed the name of that one). d I thought the 40P or one of the SA 40s had a braided wire recoil spring?? any chance you can change or modify the slide/comp to accept another recoil system?? use the sprinco system with a short recoil spring?? can you post photos of the gun apart?? see what that reverse collar looks like??
