Yup. Pretty much a Security/Service/Speed Six sized gun which is pretty close to a K frame Smith.
If you're looking to buy a new gun a Smith 66 is about as small as you can go with 6 rounds of .357, the Kimber K6S might have a small advantage with the way the cylinder is shaped like a hexagon. If you don't mind buying used I'd say buy a Ruger Six series gun, they can be had for $350 to $550+ depending on model, finish, and barrel length.
Go to the biggest gun store in town and fondle a bunch of stuff because that's the only way to really understand the size and feel of the guns.
