I've shot several K38s over the years and found that once in a while you will come across one that shoots spectacularly well. Have no idea what is responsible, but it happens.

Have heard same from a couple of other people over the years. And I remember Skeeter Skelton tested 3 K Masterpieces in "Shooting Times" (believe it was late-1970's) and the K38 he got turned out to be one of those extra-accurate ones. Grouped one ragged hole at 20 yards or so. He said something like "I didn't think I needed another .38 Special, but this one isn't going back to Smith". Or words to that effect.

I remember finding a NIB factory single action K38 some years ago and was hoping it was going to be in that exalted category. But its accuracy was run-of-the-mill so I sold it.
