My gun is not an Omega, does it make a difference??
>> The non-Omega models are the original design. The P01 was designed and built to compete in a competition for European police agencies, and having a decocker as standard equipment
was in the specs. Therefore the original gun was never designed to be be "either/ or".
About 7 years later, CZ introduced the "Omega trigger system" for the P07 and P09, which they added to the
second generation P01. The Omega
does allow selection between decocker and safety. Those selectable parts are/were included in the box with the new gun. These parts are/were changeable by the gun's owner.
The differences between the first and second generation receivers AND internal parts are
significant. The Omega parts cannot be added to a non-Omega gun. If you want that choice, then you
MUST buy an Omega-style gun. There is no way around that.
>> Not only is there no
change option for the original model, unwary owners who disassemble the original decocker system are in for a BIG surprise because the mechanism is extraordinarily complex. Unless you are a master gun smith, hold a degree in mechanical engineering, or repair complex mechanisms (such as clocks/watches) for a living, then you will be hard pressed to re-assemble this mechanism successfully.
Hope this fully answers the questions about which model you own and the original question pertaining to the decocker. As explained earlier, the non-coated rails are a non-issue.
