There was recently a post about nitriding and how it hardens the surface. Apparently to a point it was recommended to complete any machining beforehand.
Is the hardness introduced comparable to heat treating? Sufficient to prevent set back in an older military Mauser of unknown hardness?
They are not heat treated,1909s,they are case hardened. I don't think the steel can be heat treated. I think Melonite QPQ would be great on any 98.
