Jelena, I don't know about the 27 items short version, but there is a 12 items short version (even reduced to 9 items) in an article in Diagnostica:
Küfner, A. C. P., Dufner, M., & Back, M. D. (2015). Das Dreckige Dutzend und die Niederträchtigen Neun – Kurzskalen zur Erfassung von Narzissmus, Machiavellismus und Psychopathie. [The Dirty Dozen and the Naughty Nine - Short scales for the assessment of narcissism, Machiavellianism and psychopathy] Diagnostica, 61, 76-91.
The authors of this article may be able to provide more information.
I would like to use the German version of the SD3 very soon, too. Have you found a German version or maybe translated it already? If not, maybe we could work on a translation together..? :-)
