It has a steel frame and slide, but the barrel is fairly short, and it is a light weapon. The first Model 39 was manufactured from 1954-1966. Virtually all subsequent Smith & Wesson pistols can trace their ancestry more or less to the Model 39. Most Model 39s are made of blued or phosphated steel, but Model 439 variant uses a carbon finish, and the Model 639 variant is made of stainless steel. There was some small use by US personnel in Vietnam, and then the US Navy modified the Model 39 into a silenced weapon (the Mk22 Mod 0 "Hush Puppy"). The 39 seemed to also be a failure until the late 1950s, and in 1967, the Illinois State Police became the first police agency to equip with the Model 39. He thus designed the Smith & Wesson 39 and insisted it be marketed, despite the fact that previous Smith & Wesson automatic pistols had been dismal commercial failures. Notes: Immediately after World War 2, Carl Hellstrom (the president of Smith & Wesson at the time) saw the large number of automatic pistols used by both sides during the war and saw that the American public would be fascinated by them. They just kept that piece and made the short run of 539's wothout making steel backstraps. Notice that the backstrap is alloy, like all of the original M-39's. The early 39's were officer owned as well as was my 539. finally decided to go to the Smith autos.shows you how long ago I started, huh? We did have a couple of M-39's, but all issued guns were 39-2's and later. This came in after I had carried one Colt Police Possitive and two different S&W wheel guns, and when our Dept. Here is a pic of my personal 539.modified, but carried on duty for about 12 years of my 35 year law enforcement career. a production model with a run of somewhere in the area of 3000 pieces. However if steel, it most likely a later Model 539. There are rumors of such, but I have never seen one. Yes, if it happens to be a steel M-39 it's VERY rare. The ejectors remained the same in both models. In the early '60s they went to a milled, short extractor with a coil spring to maintain tension, also in a different, smaller milled recess in the slide. The original M-39 had a long, spring steel extractor set into a recess in the slide.they had a tendency to break.
