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

/ forgottenweapons
www.floatplane.com/channel/Fo...
Cool Forgotten Weapons merch! shop.bbtv.com/collections/forg...
The MP-34 was made by Steyr-Solothurn in four different calibers - 9x19 for the Germany army, 9x25 for the Austrian army, 9x23 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.

@Graham Nah, be easier to get a machinegun dealer license. Wouldn't need to cut it up at all, it could be registered as a dealer sample, and you might even make some money renting it. Still plenty of movies needing Germanic weapons for props and everyone loves the gun ranges that will rent you a magazine or two through a full-auto. A lucky find in the attics of Bolivia could become the start of a beautiful business empire.

[@genericpersonx333]

@Graham You can't assemble it again as a working machinegun except with the right licenses, and the same licenses allow you to import it as a complete unit so no harm need be done to the gun. If you make it a parts kit, you are destroying a complete weapon to have a wallhanger or spare parts.

It's possible that they could have had sales of MP-34 in 45acp to Norway. Norwegian Army pistol being M/1914 11.25mm (Norwegian built Colt licensed 1911 in .45)

[@troy9477]

Nice. The replaceable firing pin and its little buffer is certainly a good idea. The clip loading attachment is innovative and creative, if a bit busy. I am surprised they sold so few 45's. With that many countries using 45, i would have expected sales to be a few thousand at least. Of course, money was tight and most national police forces down there used various Mauser carbines, which they already had. That one had a rough life- lots of chips and gouges on the stock in addition to the metal wear you point out. I shudder to imagine them possibly being piled in arms rooms rather than kept in proper racks. Third world countries often do not take the best care of their firearms. Great video as always. Thank you

[@Arkeo36]

Dauerfeuer literally translated means "throughout-fire" as in "fire through the whole magazine with one pull of the trigger."

I agree with nirfz, Dauer means steady, permanent, continuous, perennial or continuant. Throughout can be translated to "immer" (always) but the meaning would be different. Have not seen one example where throughout has been translated to Dauer- in German. What you explain sound more like durchgehend (throughout [all the time])
