Get a S&W 442 which is an alloy frame 5-shot steel cylinder .38 SPL 2" concealed hammer. The frame won't rust. The cylinder is blued, but it'll be covered by the holster. The .38 SPL is fine, you can load +P for real. The 2" barrel is fine for short range. You can get a Crimson Trace grip w/ laser. If you like it but want the option of .357 Mag, then upgrade to a S&W alloy frame, titanium cylinder, magnum model, there are a couple of options. The reason I suggest starting with the 442 is it is fairly inexpensive and much lighter than the steel framed models like the 642.
