Many knife makers have asked about this. You will never have another pin show if you do it this way.
Use a tapered pin reamer 4/0 from McMaster for 3/32.
Clean the pin stock and the hole w/ Acetone
Use a pin press
Use the flat side of the hammer polished / to do the final work.
Used this method maybe 15 years and don't recall one ever showing

when you hitting a pin it swells from the bottom up.
