The correct word is " banned ". FIE, Firearms Import and Export, made their fortune from importing knifes, firearms and other small sporting ( and non sporting ) items from Europe. Their goal was not quality but cheap or inexpensive products. The knifes were soft steel and guns of low reputation. The 1968 Gun Control Law set certain standards a firearm had to pass before it could be imported. Size, strength, sights, and so on. The laws purpose was to limit the importation of cheap Saturday night " Specials " { our own home grown manufacturers could handle that job

} On the most part they were successfully but unfortunately a few good guns were caught in the web such as the Walther PP and PPK. FIE firearms are held in very low regards as to quality and dependability. There were many efforts made to get around the law such as adding target sights to an already existing model but most of these import firms did go out of business. As to value, see the second post on this thread.
