User Romukom, over on the CZ forums made some good reference animations that illustrate the CZ 75 variant action timing. CZ Action Timing https://czfirearms.us/index.php?topic=73586.0;topicseen

Strange. I would inspect the Main Spring Plug and the Hammer Strut and the Hammer Spring for burs. Edit: I gave this some more thought. Seeing as how you have tried differnt Hammer Springs and the inconsistency persists, i would check that the Trigger Bar is not binding up. Possibly on the Trigger Bar Spring or a foreign object.

In CZ 75 variants, the safety and decocker parts are located in the frames rather than the slides. Though not all slides are interchangeable in all cases the decocker and safety model slides are generally very mechanically similar. There is only one full sized, polymer framed, CZ 75 variant. It is the Phantom and it is only offered as a decocker.

Interesting, i had not heard this subject come up before.

As far as i can tell, this part is not listed in the exploded drawing for the P-07/09 manual or sold separately. It may be worth while to contact CZ USA to see if they have any in stock for replacement. I believe that the original pin is a typical metal roll pin.

Good stuff. Glad to hear that things worked out well.

The CZC DA/SA Flat Trigger requires a Short Reach disco to function. With it installed you can adjust the Hammer Spring/Firing Pin Spring weight or get an Extended Firing Pin. If you are reloading, a softer primer may be an option. I am not aware of any method of increasing the DA Hammer travel with these discos installed.

The Short Reach (CZC) and Reach Reduction (CGW) discos, shorten the Double Action pull length and as a side effect make the DA break earlier. Edit: Spelling.

Buy more CZs........to work on.

In my expediences dealing with the subject, it is not the extra parts in a CZ decocker that throw people off, it is the difference in how the Sear Cage/Ejector is retained into the Frame. Reassembling a CZ 75 decocker can present an increased challenge over a safety model, especially for those without the right mindset, tools and knowledge. Limits to manual dexterity can also figure into the equation. Though this also applies to safety models, it may apply more so to decockers in my experiences. While i find working on CZ decockers fun, i can see why some folks choose to avoid it. I generally try not to dissuade others from working on CZ deockers, but i recognize that it is not for everyone.

To add to what has already been posted, safety models can be converted to Single Action Only while this makes little sense with a decocker. Because a safety model can be converted to SAO you can increase the Hammer Spring weight without increasing the DA pull weight. Some folks prefer the feel of a Single Action pull with a higher weight Hammer Spring. This was already touched on but the safety levers can make a nice strong hand thumb rest. I agree that the myth of CZ 75 variant safety model Trigger superiority will never die. I have encounter the subject many times since i got into tinkering with CZs. It is nice to see this subject come up and be correctly explained in detail.

It is my understanding that the only way to find out is to try it. In some cases barrels will drop in, in other cases fitting is required. It is also possible that the barrel will fit too loosely in the other slide, this could contribute to a inconsistent lock up.
