Sorry I'm wasting you guys' bandwidth.
I like S&W revolvers., but the newer ones are cheapened.
Now, so I don't waste bandwidth- anodizing is a very hard aluminum oxide surface. It can be dyed any color, or left natural. Anodizing is produced using electric current and acid compounds. It holds up fairly well, considering the aluminum beneath the surface treatment is soft.
The gun paints (clearcoat, etc.) are still paint. They are much softer than anodizing-probably softer than the underlying aluminum. Paint, IMO, is for the hobbyist, not manufacturers-though it seems this trend is expanding.
