Alpha Sierra, thank you very much for your input. I had no idea that the trigger return spring was a failure point caused by DA trigger pulls. I also appreciate the link for CGW parts. Would you mind sending me a PM of the links you mentioned earlier in the thread? While I have the gunsmithing video, the more information I can access, the better off I will be. I had intended on buying tools for maintaining my CZ shortly, this breakdown has accelerated my timeline. As this is a common failure point, it does give me more confidence to stay with the CZ I bought instead of replacing it with another brand.
Carnifex, thanks for sharing the link for the IPSC-legal trigger return spring replacement from CZ Custom. I have to agree with Big T that I do not like to be a cheat. That the TRS has an identical pull weight to the factory spring and increased reliability is exactly what I am looking for.
Does replacing the trigger spring pin with the CGW version (which is easier to install/remove and includes a slave pin) really violate the spirit of the IPSC rules? I can understand not using the CGW trigger spring as it decreases the DA pull weight by half a pound, that is cheating. But is installing a non-factory pin which offers no mechanical advantage to the function of the pistol cheating?
