Q:  Were there any AG Date Code P7M8s? 

A:  Yes, HK USA has said that the last of the P7M8s have been assembled and imported by the new HK USA Location in Trussville, AL and this is an example of one so marked.  Allegedly, there are 500 units to be imported, with another "rumored" P7M8 Commemorative (like the Jubilee)
