I "cheated" with the finish on mine, Rich--That's what the machinist who helped me get up up to speed working with my little lathe almost 30 ago would have said about applying a file to establish a final surface. After that, 220/360 grit with a wooden paddle backer; and finally purple Scotch Brite.
O.D. depends on I.D., which is larger on the 9mm. I imagine that the wall thickness of the bbl is a bit greater, too, to handle the greater pressure of a 9mm. Yours looks good and I bet it will look even better on a pistol! Now I'm wondering if there was ever such a thing as a 9mm barrel with pencil taper, square sight block. I seem to recall that the 9mm barrels on commercials were "military" profile?
