As much as I love that quote, I'm pretty sure it's fake. After I heard it I did a little research and I couldn't find a credible source that attributes it to Hitler.
Correct, there is no source for that quote and the language is not of the time period. However, the following can be attributed:
er größte Unsinn, den man in den besetzen Ostgebieten machen könnte, sei der, den unterworfenen Völkern Waffen zu geben. Die Geschicte lehre, daß alle Herrenvölker untergegangen seien, nachdem sie den von ihnen unterworfenen Volkern Waffen bewilligt hatten.
[The most foolish mistake we could possibly make would be to permit the conquered Eastern peoples to have arms. History teaches that all conquerors who have allowed their subject races to carry arms have prepared their own downfall by doing so.]
--- Adolf Hitler (1889-1945), April 11, 1942, quoted in Hitlers Tischegesprache Im Fuhrerhauptquartier 1941-1942.
