I saw one article that said that even though the injunction was put on, it means that all of the magazines bought across state lines before this court ruling but during the ban can now be unhidden because they can claim they bought it legally during this time.
The example was 30 round PMAGs (maybe a specific gen) because they came out after the ban so anyone with them had to get them after the ban was in place and could not claim it was grandfathered. Now that doesn't matter.
