Stop looking at the grass on the other side...you won't get there. Pick the one you like to shoot best, and use it often-- the more you shoot, the more you will learn to live with it. Best is the (-) connector with a 6 pound trigger spring, and reduced power striker plunger spring, and leave all other parts stock then be happy with what you have.
Resign that every gun is different, and feels different (I own several 1911's, they all feel different, I also own several Glocks, and they are not identical either). Trying to turn one into another will just be an exercise in frustration
