Thanks!I spent maybe an hour,watching tv but the scratches werent deep.Took grips off and cylinder out before polishing,the Mothers paste really worked well,turned the wash cloth black,it would be well worth your time on that 64-3 even if it took longer,just keep going over it till you are satisfied.Thats what I love about stainless pistols,if a blued gun you cant do anything with it,it is what it is.Anyway pre lock smiths are climbing in value and wont get any cheaper,they started putting the lock on them in 2000.You cant go wrong with a pre lock S&W,good trade!
