Wow, that's a pretty good report! Sounds like you can shoot it!
I had the same reaction to mine. I didn't really want to like the P-09, but, once I shot it, I was hooked. I could gripe about the plastic feel and sound, but not about the results. The results were as good as I had been able to do with some very expensive reworked all steel guns. In some cases, better.
I might clean mine when I put in the latest CGW trigger parts. Not before. Maybe not even then, except for the how-to video.
