MachIVshooter, it is all your fault! I am now looking for small milling machines to show up on my local Craigslist... Weaponsguild may have helped, but you definitely are in the act of pushing me over the edge!

You should look into case/surface hardening.... other than a pretty heavy trigger pull on account of the wide, deep and hooked sear engagement I gave it due to the use of mild steel for fire control parts.
Isn't that precisely the kind of issue that surface treatment/case hardening is supposed to address?Unfortunately, A36 is so unpredictable in it's carbon content and crystal structure even within the same piece...

It won't change the overall structural characteristics of the part significantly, but if you're worried about the geometry of a sear, for example, changing as the result of wear, it will eliminate that problem.I'm no expert on case hardening, but really all you're doing is adding carbon to the surface (a few tenths to a couple thou deep). It does nothing to alter the grain structure, and the martensitic transformation in A36 is highly irregular/unpredictable due to the inconsistencies in the matrix.
