You'll need to be more specific - there are 5 pistol models that use .40 S&W rounds. They are: -Glock 22 -Glock 23 -Glock 24 -Glock 27 -Glock 35

"GAP" when referring to Glock refers to a caliber. A few years ago, Glock designed the .45 GAP (which stands for "Glock Auto Pistol" as a way to get a .45 caliber cartridge in a smaller frame gun. It was a failure. There is nothing wrong with the cartridge, but it just doesn't do much the .45 ACP won't do.
The companies, or the firearms? Glock USA is an importer. Since Glock pistols cannot be shipped as is due to the provisions of the Gun Control Act of 1968, they have to be shipped with adjustable sights in order to be importable. Glock USA receives the pistols, removes the adjustable sights, and replaces them with the standard fixed Glock sight, manufactured in the US. The firearms themselves are pretty much the same, except American Glocks are sold with American made sights. The only other difference is that the .380 ACP Glocks - the Glock 25 and Glock 28 - are not available in the US as they cannot be made to meet the criteria of the Gun Control Act of 1968.

No. Because a Glock 26 is chambered in 9mm, as a Glock 23 is chambered in .40 s&w. For example you can use a Glock 22 (full size) in Glock 23 (compact) and in Glock 27 (sub-compact) But you cannot use Glock 27 mags in Glock 23 or Glock 22.
