Norseman, I don't have any idea how many 1911s I have repaired, customized, or built from scratch (custom parts) over the last 35 years. What you see is common on some mil-spec pistols, and is nothing really out of the ordinary.
I also don't know how many so called mil-spec 1911 pistols have been built over the years by various companies. They all have a little different take on what is mil-spec. Springfield is one of the better ones.
Just enjoy the pistol.
