I have a Sanchez NIW dated 4/89 contract mag, Ohio. Has black follower. Basically mags made during the ban are dated and or marked LEO military use only. Now if you live in a current hicap ban state you still can not posses any high cap mags made after ?sept94? I have had some say the ones with the green followers are illegal?????? OK so what about the prebans I have needed to rehab? You best bet is to get a Receipt from the dealer with a good description and state they are "PREBAN" this may at least get you some leeway. In the long run, I would think if you have drawn enough attention to yourself to question your status of your mags you might have bigger issues.
