I recently found a used S&W Model 39-2
IRM can attest that in California finding any vintage handgun is difficult. The Model 39 was apparently an improved P38 pistol. They are so similar that the 39 magazines will work in the P38. I've never seen a P38 for sale here in California. I guess that it is one of those guns that are held closely because they work and work well.
On another note: when Herman Goering was surrendered to American forces there is a famous photo of him handing over a S&W .38 to his captors. He looks a bit annoyed that they'd do that to him. Victory model?
