Question: Why? Seriously. I have three .38s and a .357. Two of the .38s are snubbies, a S&W M-36 and a Charter Arms Undercover, and one is a 4" barrel Taurus that was my father's. My .357 is a S&W M-19 4.25". I shoot all of them on occasion, but by far the M-19 the most, and usually with .38s in it. I carry .357s in it for "business" loads. Unless you are wanting to go to a smaller frame, such as a J frame S&W, or you find a really good deal on a .38, why buy one? The .357 of the same size category, as you know, does the exact same thing as a .38 and gives you the option of also using magnum loaded cartridges. A .357 is just a long .38 that can handle higher pressures. I mean, you know that. You have one. Now....If you are looking for an excuse to get a new gun, by all means do so. And, if you really just want something that is officially a .38 only, by all means go for it. That's the best reason I know of, right after needing one, is because you just want one. Enjoy whichever way you go with this.
