I have an M&P full size and I love the Apex trigger on it. It's so much better than the factory trigger. I don't know who came up with putting a joint in the middle of the stock trigger but that's a terrible idea.
Yes, it seems so. I'm glad you mentioned that the hat looks a bit out of place, because it does. However, as the other guy mentioned, I doubt anyone would feel self conscious about wearing it at Pitti.
