Good to hear a positive comment on here, I don't have the P09 but I do have several other ASG guns and have had a great experience with all of them. All of my original generic Wingun DWs are shooting as well as they did on day one after tens of thousands of rounds and my 715 is quickly chewing through the pellets as well. My classic CZ75 is a masterpeice, the external barrel has certainly benefitted from machining and it is very difficult to spot the cast components from their exterior faces.
When it comes to the old "known fault touted round the internet", a lot of it is just gossip and ignorance. One of the (many) downsides of social media and the rise of the self proclaimed you tube expert is that they provide a ready made audience for people who have little experience and really don't know what they are talking about.
