Rabbi:
I have four 1911s that have been hard-chromed, and they seem highly resistive if not impervious to holster wear. Additionally, hard-chrome seems to resist scratching better than stainless steel, and I have even had two stainless pistols hard-chromed.
However, while they are beautiful pistols, and I carry them regularly, I would not carry, let's say, a polished blue Python. If I had a beautifully blued pistol and wanted to completely avoid holster wear, I would not holster the pistol.
I have a friend who CCW but brings his polished blue Python to the range practically in a baby's blanket. We Ooh and Aah, blast some magnums downrange, then carefully wrap the Python in the blanket for the trip home. I am careful with my little children (real children, ages two and three, not 1911s) but feel that I am just about tossing them in their car seats when I consider the handling of the Python.
If you find that your pistol wears prematurely (and I think that muzzle wear is inevitable for a blued or painted pistol), you might want to consider hard-chrome. I have used Tripp, Metaloy and Metalife with outstanding results. All three shops are staffed by highly experienced gunsmiths, so your pistol should be returned properly assembled and in top notch condition.
Best luck.
