It is easier on the hands. It still increases your grip without being painful after a 100 rounds. Checkering can be made less painful by blunting the points. But most people leave the points sharp as its the sign of a quality checkering job.
While not as well done and pronounced as yours, I had a Browning High Power that I wanted some texture on the grip. I experimented using different ways of doing so and came up with this using files and a mallet. I have since done 10 different guns for different people that I know.
