Finally, finally, found one. Have been searching since 2008.
It's the 2005 Hardkick Version. The Prototype Phase II features the Heavy Weight slide.
Scored a pretty good deal. It came with a lot of uninstalled extras.
Accessorized... [Now with TM LAM Unit]
Overall I'm very satisfied with my purchase. It feels very solid and sturdy. Afraid I can't shoot it as of now because I'm scared of Green Gas. I guess I'll be getting some HFC134. Anyway, I'm happy. I've finally found my dream gun.
