What is the difference between glock US and glock austria?

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.
