Based on your requirements, I'd go with a S&W M&P. I believe they are made domestically, and they are starting to have a loyal following.
I've only shot these guns a couple of times, but they shot very well when I used them. FWIW, I do own a S&W MP15T rifle, and I like it so far (it is still pretty darn new).
Honestly, the S&W M&P pistols would fall below a Glock or Springfield in my mind, if only because the guns from the other two companies have been taking care of business on the street for a longer period of time (I like a track record on a gun before I stake my life on it). Anyway, I moved the S&W to the top of the heap for you because of the fact that you want an American made gun.
Again, I've only heard decent things about these guns, but I don't know them all that well myself.
One thing I don't like about the M&P line is the magazine disconnect safety... Personally, I want the gun to be functional if there is a round in the chamber, period. I don't buy into this line of thinking that this is an important combat safety mechanism which allows you to drop the magazine if someone is grabbing your gun away from you. To me it is obvious that whoever created that argument has never had someone trying to take a gun away from them! If the gun is going to be lost to your opponent, then I'd say that the odds are strongly favoring an outcome in which you are not able to remove the magazine to begin with. And, the other argument I often hear about it preventing accidental shootings is equally silly... Treat weapons correctly, and keep them away from children. Do that, and you don't need an extra safety. Mechanical parts break, and I like to keep mine to a bare minimum when possible!
