The MP34 (Maschinenpistole 34) is a submachinegun that use by the austrian police and subsequently by unit of the German Army.An exceptionally well-made weapon, it was used by some forces well into the 1970s.

HISTORY OF MP34
The MP34 was based on a design for the MP18.Restrictions on the manufacture of certain armaments within the 1919 treaty of versailles forbade Germany from manufacturing certain types of weapons, such as light automatic firearms.To circumvent the treaty, Rheinmetall acquired the swiss company "waffenfabrik" solothurn in 1929 and began secret production of a prototype. What was to become the MP34 was originally designated ‘S1-100’ using the company’s standard naming convention.

OPERATION
The MP34 was a selective-fire weapon firing in blowback mode with an open bolt. The return spring was located in the wooden stock and was linked to the bolt via a long push rod, attached pivotally to the rear of the bolt. Easy access to the bolt and trigger assembly was via a hinged top cover which opened up and forward by depressing two release catches. This makes cleaning procedures very easy to perform.32 or 20 round box magazines were fed in from the left side and the magazine housing was angled slightly forward to improve cartridge feeding to prevent jams. Additionally, the same magazine housing incorporated a magazine refilling feature. An empty magazine could be inserted from underneath and locked in place. From above stripper clips could be fed into the magazines.

SERVICE
In 1930, the Austrian police accepted the S1-100 as the Steyr MP30, chambered for then standard Austrian 9 x 23 Steyr pistol rounds. The weapon was also exported to Chile, Bolivia, El Salvador, Uruguay and Venezuela, and was sold in limited numbers to China, in 7.63 x 25 Mauser calibre.
With the 1938 Anschluss between Germany and Austria, the German Army acquired most of available MP30s and MP34s. A number were then re-barrelled to chamber 9 x 19 ammunition and issued to German troops as the MP34(ö) - Maschinenpistole 34 Osterreich (literally "Austrian Machine Pistol 34"). Production of the MP34 ceased in mid-1940, and manufacturing lines at Steyr moved over to the production of the MP40 – a much simpler designed weapon and far less expensive to produce than the MP34. As a substitute standard small arm, it had a relatively short combat service once quantities of the MP38 became available, though some MP34s were used by Waffen SS units in the early stage of the war in the poland and france.
