This may not be the right place to put this, but since the Model 66 was started in 1970, I thought that I would place it here....

I have heard that the model 66 is the smoothest shooter in either the .38SP or the .357 formulation, but that you have to be careful about the type of cartridge used in the .357 calibration. I am looking for a revolver to supplement my Bodyguard .38SP [which I will be using as my CWP revolver when the CWP gets here] which is smoother to handle without such a rough recoil.

After reading about the different model .357 S&W revolvers, I am interested in the model 66 because

I can save money on a quality used model.
It has a "target-like" trigger and I certainly like the trigger pull on my 617.
It is a supposedly the smoothest shooting of the K frame .357 revolvers.

Is the model 66 that much smoother?

Is it difficult to get the lighter .357 cartridges? Or should I restrict my search to the newer L frames?

I'm in no hurry to buy but would appreciate your wisdom and input.
