Springfield Armory's 1911's are at least still American made.
The XD pistol was and still is Croatian( Take a look, it even says so on the grip in the photo)
I'll let you do the math.
You want a poly, go with either Glock or a S&W M&P. The Glock is Austrian, true, but it's design has held up quite well over 25 years.
The Smith, Well it's only been out on the market for 4-odd years, but it's at least American made, has had a few years to work the bugs out, I have no concerns with it's polymer frame ( as of this year there's a .357 Sig model out--if it can handle .357 sig , it's plenty sturdy enough for .40) it has an ambidextrous slide stop, it's mag release can be swapped out by the user to be either right or left handed, it can be had with or without a thumb safety, it can be had with or without a mag disconnect, in all free states the mag capacity for each caliber in the fullsize models is the same as Glock, it's hands down far away better than Smith's early Sigma series, and as far as all the "vs. Glock" comparisons, as far as handling and ergonomics it doesn't "compare" with the Glock--it kicks its *** hands down for me. YMMV
