Over at the Volokh Conspiracy there is a post about the history of magazines with greater than ten rounds capacity. Very short version: The 9th Circuit court has a case challenging the greater than ten round magazine ban, called Fyock v. Sunnyvale. David Kopel co-authored an amicus brief that gives the history of such things. Many interesting factoids for gun hardware geeks to appreciate, and many things for gun-rights people in general. Many things I knew, many more I didn’t. Worth a read.
It’s another good case to watch.
