whats wrong with the holes??? if there are three of them, that may be the Ruger "pattern" .just leave them be, put in plug screws ( cap heads),,,as for a reblue ,about ANY decent refinisher can do that job, and easy enough to polish ( prep yourself and just send it out and get the receiver dipped) cheapest way to go............any high school shop class student can polish the upper receivers of the Ruger semi auto 22s ,they are a piece of cake,,,wish I had a nickel for every TWO that I have done the past 53 years.... :roll: :wink:
all done by hand......... 8)
