Almost all of Springfield's frames and slides are made in Brazil and their basic guns, which is what you're describing I think, should be marked " FI Brazil" on the dust cover.
The custom guns- such as the Trophy Match- are a bit different. SA imports partially machined frames and completesthem here. Since it ain't a gun until the slide rails are cut (which they do here) they can legally say it's made in USA.
But that doesn't mean there's anything wrong with them, and I think the Trophy Match is probably the best buy around for a basic accurized pistol.
