Buzz, Im not a craftsman who does this stuff but my impression is flat top checkering is more difficult to execute properly than pointed. Seems to me sharp checkering doesnt require every line to be exactly the same depth as flat top does to result in flat diamonds all the same size. And I dont think it would be out of place on a modern gun. In fact, it might draw envious responses from fellow shooters.
