S&W 439 is what generation?

[jrothWA]

Think its the third, with adjustable rear sight and steel frame??

Local shop has a 439 for $400.

That would be a second-generation S&W.

[jrothWA]

and the 439 was third?

Thanks for response.

Here is a link that describes the three generations of S&W semi-autos. I have a 3rd generation 5903. A 459 is a 2nd generation and a 39 is a 1st generation.
