The Model 36 Chiefs Special was produced from 1950 to 1999. It still survives in modern metals in the form of the Model 637, the Model 60, the Model 36LS, the Model 340, the Model 360, and their variants. Contemporary J-frame S&W revolvers are actually built on the J-Magnum frame rather than the true J-frame. If you compare a current J-frame with an original Model 36 or 60, you will notice that the frame and cylinder are slightly longer on the new guns. They are all built to the length that will accommodate .357 Magnum, even the models that are chambered for .38 Special. All of the new stainless J-frames today are chambered for .357 Magnum rather than .38 Special. (There have been variants produced in the Model 60, 66, and 640 that are “re-issued” in .38 Special, so check the gun you’re looking at.) If you go to the store today to buy an all-stainless J-frame, if it is new, it will be chambered in .357 Magnum as will be the Model 360 and the Model 340. You can, of course, shoot .38 Special in the .357 Magnums, but Smith & Wesson finds it necessary to enable their new snubs to chamber .357 regardless of how painful they may be to shoot. The stainless and alloy Airweights are still chambered in .38 Special and rated for +p, and IMHO, they’re the best value and most utilitarian members of the class.
The question of using modern +p ammunition in these old revolvers often comes up. While the all steel early models will probably stand up to a limited amount of +p, they were not designed to handle it. Loads like Speer 135g +p and Cor-Bon DPX did not exist when these guns were built. The safest course with the Model 36 is to stick with standard pressure loads if you choose to shoot it. +P absolutely should not be used in the early Airweights, the Model 37, 38 and 42. And, of course, the all aluminum “Aircrewman” revolvers should not be fired at all, even with standard pressure loads. The new Airweights, the Model 637-1, 638-2 and 642 are rated for +p and will handle it without damage to the gun.
The Model 36 and its children have endured for half a century and the odds are good that they will be around for quite some time.
