A couple years ago, the discussion of MIM vs forged vs cast was discussed at length over on the Ruger forum. Numerous posts offered links to various web sites, metallurgical studies, etc., etc. One fella offered many case studies regarding the subject. The results were interesting; when it comes to manufacturing precision, tolerances, durability, economics, and design geometry, MIM parts are every bit the equal of forged, and superior to cast.
