FWIW, most of the famous gunfights of the Old West, specifically including the OK Corral, were precipitated by law officers attempting to enforce “gun control” laws within city limits.
Also, recently read an essay on the history of Bowie knives. They were outlawed, prior to Civil War, in a bunch of southern states. I suspect concealed carry of pistols was also often outlawed. Of course, the 2nd arguably didn’t apply to the states at that time.
Yes, it was -- this because the only reason to hide weapons was to engage in unsavory business, as all law abiding citizens could and did carry openly -- see New Mexico's State Constitution (Art II, Sec 6) as an example.
That was, of course, before the demonetization of guns and the falling out of everyday carry by citizens.
