How come gun dealers in the US do not sale the Glock 25 Glock is a manufacture in Austria?

The Gun Control Act of 1968 set forth certain criteria which firearms manufacturers must meet before their firearms can be imported for resale on the US civil market. Even the Glock pistols which are sold in the US must be shipped with adjustable sights, which are then replaced with fixed, US manufactured sights once they arrive. The Glock 25 does not meet the criteria sufficiently to be allowed for import onto the US market.
