After encountering Italian Villar Perosa machine pistols in the field, Austro-Hungarian troops requested a similar weapon. The project was given to FÉG to work on, and the result was the Pistolen-MG Model 1917: a pair of Frommer Stop pistols with long barrels and 25-round magazines, redesigned to fire from the open bolt, mounted to an adorably tiny tripod and spade grips.

Only a few dozen of these were made for testing, and they were not accepted for military service. Many thanks to Joschi Schuy for giving me access to film that fantastic surviving example for you!
