Just one difference. S&W revolvers are all forged, even the alloy frames. Then they must be machined to accept the parts.
Those S&W .22 autos (except the Model 41) are neither forged nor cast. They are made from an aluminum extrusion in the shape of a frame, then sliced like a loaf of bread to make the basic frame. There is machining, of course, but aluminum is a lot easier on machine tools than steel.
