You can save yourself some money and just wait until you have about 500 rounds through it and the trigger will be just fine.
I have seen very nice "trigger jobs" where the people didn't want to wait for it to wear in. Just took the side plate off and filled it with toothpaste and spent the evening dry firing at the TV and then cleaned and reoiled it. Smoothed right out!
YMMV
Yup. And, to lighten things up -- different from smoothing things up -- there's Wolff springs. You do want to make sure that the gun will still function reliably after putting in a lighter hammer and return spring, but that's just another excuse to go to the range.
A really high-end trigger job -- like the ones that Tom Castonguay or Cylinder & Slide are capable of -- may make S&Ws a little slicker than the combination of Wolff springs and a toothpaste job, but probably not much.
(Colts are much harder to work on, I'm told, and definitely more expensive.)
