Very likely, one of the things that finally lead to the Concealed Handgun License act was Democracy. throughout most of history, a cowboy or ordinary citizen or certainly a minority group member would be arrested for carrying a handgun but a banker, or professional would be left alone. With the move toward more universal enforcement of laws, the favored classes lost their immunity.
Along the same lines of what JohnKSa just said, I'm pretty sure the opposite was true. After the supreme court started striking down laws which specifically restricted the rights of black people, the politicians in the South started getting clever. A bunch passed concealed carry license laws, which spread like a plague, and a few followed Tennessee's lead, by limiting what guns you can own.
By making concealed carry laws with ridiculous restrictions, they just made a more legal way of selectively disarming blacks. A black person wouldn't be able to afford to pay for a CCW or meet the requirements (just like black people couldn't afford poll taxes nor pass literacy tests, in order to vote). But rich white people, cops would just assume had a license. And if they were caught anyway, someone would no doubt make a license for them, and date it sometime before the crime was committed. Of course, no Southern DA in their right mind would actually prosecute a white man for carrying a gun around without a license.
This still shows up if you compare gun control laws in the South vs. the North. In TX, a CCW costs $140 plus training costs, needs a very long training course, fingerprinting, I think a drug test, and can take several months to process. But in PA, a CCW is $19, with no training, no fingerprints, no drug test, and takes only about 1-2 weeks usually. One of the Carolinas says you can't carry a concealed firearm on
any private property, without the explicit consent of the owner. So if you walk on someone's lawn while carrying a firearm with a CCW, you've committed a crime. But in PA, you can carry a firearm wherever you darn well please, except for state and federal property.
Tennessee's "Army and Navy" law is the origin of the "junk gun" and "saturday night special" laws. That law said that the only handguns which were legal to buy were Colt Army and Navy revolvers, which are very large, heavy, and expensive compared to deringers. Much too expensive for the average freeman to afford. Of course, the law was selectively enforced on black people only. All non-Army/Navy guns that white people owned would be assumed to be grandfathered because they were owned before the law was passed, even if you were caught walking out of the gun store with one.
