So much misinformation in this thread it really hurts my head.
Springfield owns a forgery in Brazil, and yes the cheaper models are assembeled there, some of the more expensive ones are assembled in the US.
Imbel is not owned by Springfield.
STI has their cheapest model the Spartan's parts built by Armscor and finish them themselves (actually great guns for the money) Their other models are US produced.
STI does no work on the Spartans. They spot check batches here in the US but they do not "finish" them here. It is more like they are blessed in TX. I would guess that 99.9% of them receive no fitting or finish by STI. If they did they would not be selling them at the price point they do. This does not make them bad guns it just makes them what they are. Armscor frames and slides with some STI parts assembled in the Philippines on its own assembly line inside of Armscor.
I'm looking for another 1911. I'm stubborn. Make that very stubborn. I only buy and own (all) American made 1911's. As I dig a little, I find there are very few, make that none that I can find, mass produced 1911's made in America. SA frames and slides are made in Brazil. Some STI's are made in the Philippines. Para USA still made in Canada. Smith and Wesson bought out by the Germans. Colt is going foreign/offshore. U.S. Marines are carrying Benelli shotguns. Kimber is hooking up with HK? Winchesters made in Japan. Besides Ruger and Remington are any decent .45 pistols made in the USA??
Aguila Blanca covered these but I am going to add some additional detail.
Really only one STI is made in the Philippines it is the Spartan. There are 3 different versions of the Spartan coming in 45 ACP and 9mm so yes 6 STI guns are made in the Philippines. All others are made in TX.
Para is now made and serviced in the US in Pineville, NC. They have been for a while now. They are making better guns these days. Still not something I would buy but they have an improving track record.
Colt is not making any 1911s off shore at this time. They have saved themselves with a cash influx for the short term and will be around for a long time IMHO. They are not going anywhere.
Smith and Wesson is a publicly traded company. NASDAQ:SWHC The co-marketing and serving agreement with Walther is over and it last year IIRC. They were never owned or even controlled by Walther.
The GI's were all made more or less by Imbel with the except of a few cuts to the frame, and final finishing. Same goes for the N marked Mil-Spec's, and loadeds. The NM serial numbers on Loadeds, TRP, and Trophy Matches were finished mostly in the US, the forgings from Imbel. The internal cuts were made by Imbel but the rest of the maching and rails were all cut and finished in the US.
The entire NM or N mark on Springfield 1911s is a point of constant confusion.
Springfield uses the prefixes of "N" and "NM" to designate 1911-A1 type pistols, just as we used "AM" as the prefix for the P9 series of pistols. The only pistols which use the national match frames are the complete custom pistols built through our custom shop. These pistols have "Springfield Custom" etched on the slide, and will have the "NM" prefix to the serial number.

NM is used in two ways by SA. One is by the custom shop to mark National Match frames which come out of the custom shop and the the "NM" in the serial number along with the SA custom shop logo.
Then there are the NM serialized guns that do not have a custom shop logo which is believed to designate final finishing in the US vs Brazil. Some believe these to be superior to N marked guns. I am not a big enough SA fan to tell you if that is true or not.
