There are a few casting companies that are putting them out but you have to complete them. I can't remember if it was caspian or essex but they had one in the white ready to go. Barrels are easy. Clark, wilson, kart, storm lake, they all make a 6 inch barrel. Dang, now you got me think'n if I should forget buying a NIB HK P7 PSP and just get going on building one.
