Stainless parts that are tumbled and chemically treated. Once you see it in person you either love it or hate it, it seems. Personally I love it. Very smooth polished feel but a dark gray color.
Ruger made long guns in target gray too. The most popular is the Super Redhawk 454. That is a nice pistol with the old lett style grips with black lam wood inserts. Very pretty indeed. Again my opinion.
