Magnas with a Tyler T grip adapter works well and looks and feels great on a 2.5" S&W model 66 No dash. I shoot this often with 357 magnums and don't find it abusive at all. In fact I shoot well (for me...eyes are failing me!) with them. I know that Pachmyers are much easier to handle recoil and there is a little precision pickup. But it's much harder to Conceal Carry with those rubber grips. Plus they don't look nearly as nice.
The nicest setup I have used on this gun and other K frame 357 magnums are the S&W RB Combat stocks
.
