I grabbed this CHP pistol from CDNN. Everything checks out except I want to improve the finish. Rifling looks sharp and possibly untouched. It just has holster wear...

So, my questions:
1) Are the black parts/pieces carbon or stainless steel?
2) How does S&W accomplish this matte finish? Do they use a particular blast media?

Thanks for helping! 😊
