I am not very well versed in the S&W semi-automatic pistol so please excuse what may be a very dumb question. While touring the gun show today I observed what looked to be a Mod. 39 Smith, I asked the owner if it was not a mod. 39 since he had a visible tag that stated it to be a Mod. 38-2. He asked about my old eyes and then handed the gun to me and I believe I read Mod. 38-2 on the alloy frame with steel slide and barrel. Seems that there is at least one Mod. 38-2. Oh, yea, it is a 9mm caliber. Since there are two first generation 9mm's what is the difference please? Thanks for the education.
