All I know is that my Ruger's are amazing performers for the price point. My tiny, light $300 LCP has done two years, five months pocket carry and over 1,000 rounds with nary an issue. My 10/22 all-weather stainless takes all the abuse I can dish out and laughs. MIM parts in Rugers don't concern me.
