I just purchased the short reset kit for my P-02, which gave me a reason to disassemble the gun and at the same time polish some surfaces. Pretty straightforward disassembly. Only snag I had was realizing that the ejector was free and pivoted on the sear pin, preventing the removal of the pin. From the parts diagram I realized this and freed the ejector. Of course the tiny spring flew across the room. Fortunately I found it.
The Omega system is quite simple and fewer parts. I polished the sear and hammer notch surfaces, lower half of the hammer that rubs on the frame, part of the trigger base and pivot area and trigger bar, top surface of ejector that rubs on the frame, FPB and lifter arm contact area. I also polished the disconnector where it contacts the hammer. Replaced the hammer spring, FPB spring, extended firing pin and spring, disconnector and lifter arm with the parts kit. Actually I put back the OEM hammer spring since it is 14lbs vs the 15lb spring in the kit.
Pull weight is almost the same. The only difference I feel is in the smoothness of the moving parts. I have to test the reset when I go to the range.
I also polished the slide rails and that feels buttery smooth when installed in the frame.
