Revolver experts, your advice

I'd say never try to do any of those WITHOUT KNOWING WHAT THE HELL YOU'RE DOING.

Yup, that would include me.

My attempt at stoning these parts was done with an FF-46 India stone.

My peerless trigger job did NOT last long.

Well, I'm not sure what FF-46 translates to in the fine, medium, coarse matrix, but I do know that I prefer ceramic stones to Indias or Arkansas, and in the 800 to 1,200 grit range.

At that point you're no longer really cutting material, you're polishing.
