I've had a S&W 60 3" full lug and a S&W model 642 Centennial .....there was absolutely NO doubt that the shorter model 642 kicked like an angry mule compared to the model 60~3inch ....when using the same 38+P loads....
Accuracy-wise, the model 60 3 incher had good adjustable sights... the 642 had groove and blade sights..... difference in accuracy was day vs night.
