Pound chops between sheets of parchment to an even 1/4-inch thickness. Season with 1/4 teaspoon salt and 1/4 teaspoon pepper. Mix dredging flour, cornstarch, paprika, 1/4 teaspoon salt and 1/4 teaspoon pepper in a dish; whisk egg and buttermilk in another.
Coat chops in seasoned flour, dip in the egg mixture and press back into flour for a craggy coating. Rest on a rack for 5 minutes and discard leftover raw-pork coating ingredients.
Heat oil in a large skillet to about 350°F. Fry two chops at a time for 2 to 3 minutes per side until golden and at least 145°F; transfer to a clean rack and rest each for at least 3 minutes.
Pour off all but 2 tablespoons frying fat and remove loose dark crumbs. Stir clean gravy flour into the fat over medium-low heat for 1 minute, then whisk in milk gradually.
Simmer gravy for 3 to 4 minutes until spoonable, season with remaining salt and pepper and spoon a modest amount over one side of each chop to serve.
