Ya done good...
I scored my second 39-2 NIB about 6 months ago - SN A437xxx. It was so nice, it deserved Nill rhomlas.
Yours appears to have the small inverted V relieved at the bottom of the frontstrap at the magazine well, so I'm guessing yours is a lower serial number, like my other 39-2.
Next to my P7M8's, the 39-2's are my all-time favorite 9mm autoloaders...
