Your best bet is to find a decent Ruger Security-Six. The square-butt is comfortable for small hands, though you can get a Speed-Six with round-butt, and that's one sweet gun.
If your hands are abnormally small, you can spend two minutes on a grinder and fit a round-butt to a Security-Six (which I did just out of preferance, but I wouldn't do it with a 6-incher). The Ruger has the benefit of being stronger, easy to field strip, and of having oversized parts. The stainless hammers and triggers (unlike S&W's MIM hammers and triggers) slick up on their own, just by dry snapping.
The S&W 686 is another wonderful choice and is arguably the best production .357 ever made. Here in Maryland I posted an ad offering to swap a mint 629 .44 mag for a mint 686 and didn't get one taker. The 686 is one of those guns (like the Security-Six) that most people just don't want to get rid of.
The 686 also comes in a 7-shot configuration, which I don't know a whole lot about. I'd look into one of those, too, if I were shopping for a .357.
Finally, and this is just my opinion, the .357 is the greatest handgun caliber of all time. I'd steer clear of the Tauruses, though.
The Ruger Security-Six can be fitted with round-butt after just a minute or two of grinding.
