Subguns for South America: the Steyr-Solothurn MP-34 in .45ACP

Cool Forgotten Weapons merch!

The MP-34 was made by Steyr-Solothurn in four different calibers – 9×19 for the Germany army, 9×25 for the Austrian army, 9×23 for the Austrian police, and .45 ACP for the export market. This is one of the .45 caliber examples, of which only about 500 were made, all for South American countries (including El Salvador, Chile, Bolivia, and Uruguay). The gun shares most of its parts with the 9mm versions, with the exception of the magazine housing, rear sight mounting, bolt, and barrel. The receiver and magazine housing are the same length as the standard pattern, which much simplified production; it just has a wider housing to fit the double-stack 20-round .45 caliber magazine. In addition, because of the lack of common .45 ACP stripper clips, the clip-loading feature of the MP-34 mag housing was left off the .45 caliber model.
