Apologies to 35remmington who's words I purloined for the title of this thread. He scribed that in a recent thread concerning 1911 reliability and that remark was actually a two sentence phrase; "Who knows the breechface isn't supposed to be straight? Are they making them that way?"
Well, got to looking and just by eyeball the breech faces of my two samples from Ruger seem to have been milled straight, with one little caveat. EDIT, IT IS THE LEFT SIDE, THR EJECTOR SIDE! LEFT hand side (shooter's perspective, the ejector side) has a slightly raised sort of "quarter moon" shaped area right against the side wall. A few thousands of an inch above the face proper, I guesstimate. The cartridge case's head does rest upon that little ridge and spent cases do show its imprint, especially loadings beyond plinking power. Some of my older cases have been so embossed all the way around to where it has obliterated the brass brand name or at least the bottom half of it. I have seen another report (complaint) about that on a Ruger forum. I never gave it much consideration since the function and reliability are excellent and the brass continues to cycle regardless the imprinted crescent dents.
Is what I notice the way it was and should be? Is it a machining error or an easy way around doing it "correctly" (or the old way)?
