Pound chops between parchment to 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 dish; separately whisk egg and buttermilk.
Flour chops, dip in egg mixture, then press into flour for craggy coating. Rack-rest 5 minutes; discard coating ingredients touching raw pork.
Heat oil in large skillet to about 350°F. Fry two chops at a time 2 to 3 minutes per side until golden and at least 145°F. Transfer to clean rack; rest each at least 3 minutes.
Leave 2 tablespoons frying fat; pour off rest and remove dark loose crumbs. Stir clean gravy flour into fat over medium-low 1 minute; gradually whisk in milk.
Simmer gravy 3 to 4 minutes until spoonable; add remaining salt and pepper. Spoon modestly over one side of each chop.
