Yes, I know Glock is Austrian, not German. Did you know that Adolph Hitler (originally born Adolph Schickelgrueber) was also Austrian?
As for a book calling Glock America's Gun, that could not be further from the truth. Originally designed and made by Gaston Glock, yes, an Austrian, the main reason it rose in popularity in the US is because it was priced ultra cheap for police/law enforcement. That didn't make it better than anything else, just made it cheaper. Same reason people shop at Wal-Mart and fill their homes with Chinese junk. Cheap! Same reason unemployment is running rampant in this Nation. Jobs are being moved to China because labor is, you guessed it, CHEAP! But all that is a different topic and has no place here. What it all comes down to in the end is that America has real gun manufacturers. Colt, Browning, Smith and Wesson etc... who have designed and built some of the greatest firearms in history. Including the M1911A1 in .45 ACP. There is a reason the MP40 was called the Burp Gun and the Thompson was called the Trench Sweeper. We don't need Glock as America's gun. We already have our gun and it isn't replaceable with a piece of Austrian Tupperware any more than John Moses Browning could be replaced by Gaston Glock. Glock isn't even in the same league.
