Im not saying MIM is bad. Im suggesting S&W switched from forged to MIM because its cheaper and brings the price down. I dont think they switched to MIM because its functionally better.
At best I think MIM is equal to forged, and most likely MIM is marginally worse than forged. But since as the final consumer I can have forged for about the same price as MIM (because a used vintage gun is about the same price as a lightly used new MIM gun), then this one piece of the calculus shifts in favor of the older gun, at least slightly.
