I have both an SR9, and an SR9C. Neither has a trigger that can be described as pulling an Edsel, upside down, a half-mile".
My friend's S&W Shield also lacks for your description.
What I do perceive, though, is that, as a 1911A1 shooter, you prefer a single-action trigger. Neither of the guns under discussion possess that. Their designed triggers require more travel, and are designed to run around 5-6 pounds of pressure.
New shooters taught on single-action guns will almost always be disappointed in striker-fired, or DA/SA weapons triggers.
Both of my Rugers, and my friend's S&W, haven't lost much actual trigger pull with firing. However, all three guns FEEL lighter in trigger pull due to the smoothing in of the fire control parts with use. Often, the best gunsmith is Mr Firethehelloutofit. He works cheap, and you know your gun much better by the end of his work.
