Colt made the gun to Browning's patent specifications.
FN did the same in Europe. Colt and FN had an "agreement" of sorts concerning Browning's patents that way. South America was more or less a free-for-all IIRC, but the lines were clearly drawn between North America and Europe in that way. Not sure where Asia fell into that...anyway.
OP, would it surprise you to know FN made their own version of the 1911? If it does, you haven't really spent any time digging into the history of the 1911...sadly WWI broke out and FN never went into serial production of the gun. There are a few out there though; tool room samples and a couple of completed sales samples that were shopped around before everyone decided to start shooting at each other.
FN never tooled back up after the war to make them because there were a ton of GI and commercial 1911s all over Europe after WWI and they felt like they couldn't compete.
Also, the original chamberings of the 1911 and all of it's prototypes would include 38 ACP, 45ACP, and .455 Webley Auto. At least those were the ones that it was chambered it (and it's prototypes) while Browning was alive. I'm sure 38 Super was in the works as well before he passed.
The FN chambering was again a mid-caliber (9.65x23mm per the internet, or roughly .38 cal - not .355) cartridge if I remember right. Again, this was while Browning was alive, so you can't really say "but it's not a 1911"...it was literally made to the patent and drawing specifications.
