I have polished a few AR trigger and hammer sears, but I wonder if I should have followed that up with case hardening. Does stoning and other polishing remove any surface hardening? Sometimes I use 600 grit sandpaper followed by crocus cloth; sometimes I use a stone then crocus cloth; sometimes just crocus cloth.
I see Brownells sells Surface Hardening Compound and I was thinking maybe I should use that.
Years ago, I polished the trigger sear on my Colt 1911 and it works fine now 30+ years and thousands of rounds later. So should I be concerned about having soft surfaces now that I have polished them? Thanks.
