Just like many countries around the world, Brazil also has its share of illegal guns being seized by police authorities, some of which have occasionally been shown in TFB and, even more often, in Impro Guns (https://homemadeguns.wordpress.com/). This example was recently found in Minas Gerais State, a habitual source of DIY weaponry.
The pistol shown above, chambered to the .380ACP round, has an unusually decent overall finish and came with a very large capacity (30-round +?) box magazine. The tubular receiver extends to a muzzle area extension made of a brass-like material. The magazine housing just ahead of the trigger guard is a box-like structure, the ejection port being vertically-located there. Since no fire-selector or applied safety devices are visible, it would seem that the contrivance is a full-auto-only gun (confirmed in one of the videos), as it’s often the case with such DIYs. Sights? Who needs them?
The video below was made by PMMG – Polícia Militar de Minas Gerais (Minas Gerais Military Police) when the gun was seized:
A second video has been obtained by TFB, and this apparently shows the full-auto pistol being (very informally, indeed!) tested on an old mattress by probable designer/maker/user prior to falling into the hands of Law. The magazine was filled with ten rounds of .380ACP ammunition, which were subsequently fired in a single burst with a (expected) very high rate of fire. And when I say “fire”, I mean it…
