@ASH556, don't sweat it too much. If a 1911 made to a concise specification runs well, do all the details mentioned matter? Maybe, if you pay for those details. I greatly admire Jason Burton's work, but even he says a lot of what he does isn't by necessity -- it is what people who buy a bespoke pistol are paying for.
The risk in buying a 1911 isn't that the design is bad or prone to malfunction. The problem is that manufacturers have inconsistent quality control, or deviate from the specification in ways they shouldn't. Getting into the 1911 without an understanding of what things can go wrong and how to address them is what will lead to frustration. Sometimes the solution to a problem is simple to address, but it's hard to avoid feeling like it should have never happened in the first place.
If one buys a Government Model .45 from a quality manufacturer the gun will probably run and run without a lot of drama. Deviate from that pattern and the chances of something going wrong increase a little bit. Get into 9mm 1911s only if you have the patience and determination to see it through if you run into an early snag. It may also take some time and expense to figure out which magazines work best in your gun.
