He said Price is no issue, but still folks keep changing his question.
You are right. Mea culpa.
However, he
also said "...limiting this to
factory semis [no custom or aftermarket tweaks]...." [italics/bold mine]
I took that to mean he wanted a
make/model you can place an order on.
So why do so many people just throw out a
platform, instead of a make/model from a factory? Instead of saying 'get a 1911', a better answer should be 'get a Nighthawk T3' [for example].
My point was that his failure to take price into account makes this exercise moot.
How likely is it that a mass-produced 'factory' gun that sells for $500 will have the same quality trigger as a Nighthawk Bob Marvel Custom, a Wilson Combat Pinnacle or an Ed Brown Classic? None of these sell for less than $3000 [the Pinnacle is closer to $8000] and all can be legally defined as a 'factory' gun. They are as much 'factory' as my F150: both can be ordered with a specific blend of features.
So, if price is no object: buy the Wilson's Combat Pinnacle and be done with it.
It also meets your standards: buy a 1911.
But a RIA can have a trigger so good an average person couldn't feel much difference [with closed eyes] for less than $1200 [counting gunsmith fees].
Thus, the question seems to also include the idea of which gun has the
capability to have the best trigger. After all, those 3 above just do all of the aftermarket/custom work
in their factory.
I do agree though: the 1911 platform has the most potential!
