I just bought a new P01 Omega Suppressor ready new in the box earlier this year. I understand your concern as I had read a lot about this problem. I went to great lengths to make sure the one I bought was a 2019 production. I have something over 500 rds through it without a bit of trouble. Not exactly a high round count, I know.
Now, mine came with the decocker installed, which is how I wanted to run it, and haven't switch back and forth between the safety and decocker. Neither have I tried to induce the problem by messing with the ejector, or disassembling the frame and its components. Is that a factor? I don't know, this is just to let you know other's experiences.
