Hey, What's up Guy, I have found two places that advertise PMI mags. I have not delt with either of these companies myself but, they advertise weekly in "Shotgun News" and "Gunlist Index etc." The first one is "SWFA" in De Soto Texas. They do have a webpage but, they only have scopes on it. I do not have their add in front of me but, I have seen them recently advertise PMI mags 20 30 40 rounds for $49.95. In addition, "Frank's Center" in Nevada at 417 667-9190 is currently running an add for PMI's as well. Hope this helps.
