I just got my latest issue of the Sportsman Guide and saw an ad for Luger magazines for $16.95, this is the lowest I've ever seen repros go for. Having only seen one once they look like a KKK mag, but I'm not really sure, I also have no Idea if they would work correctly so neither I nor Pete are recommending them and neither of us have any connection whatsoever with this company.
