I just bought a Smith and Wesson Pre-Model 10 Snub nose on gunboker which was advertised as .38 Special, however the gun shop I got it deliver to said that .38 spl didn't fit in the cylinder and neither did .357 magnum, but .38 S&W did fit. I haven't been able to get over to the shop to pick it up yet so I haven't seen it up close. It has no caliber markings. Did they make K frame Smiths in .38 S&W? I haven't come across one before, Or did the gun shop possibly try the wrong round or something? Thanks
