Here's my 539. It's a nickeled one, definitely scarcer than the blued version. The factory letter states "ambidexterous safety". I don't know why the safety is stainless; perhaps that's all they had (made for the 639?). Does anyone else have either a stainless or blued ambidexterous safety on a nickeled 539?
