A incrível pistola Kolibri de 2,7 mm!

This video provides an in-depth look at the 2.7mm Kolibri, the smallest centerfire pistol ever produced, originating around 1914. It details its autoloading mechanism, unique design lacking a trigger guard, and surprisingly low ballistics, barely capable of penetrating cardboard. The presentation highlights its historical context, inventor Franz Pfannl's background as a watchmaker, and its design lineage from the Steyr 1908.

This review from Forgotten Weapons, presented by Ian McCollum, details the world's smallest centerfire pistol, the 2.7mm Kolibri Autopistol. The video provides a historical context, designer information, and mechanical overview, emphasizing its extreme concealability and unique status among firearms. McCollum uses comparative pistols like the Walther PPK and Model 9 to highlight the Kolibri's diminutive size.

Ian McCollum of Forgotten Weapons provides an expert overview of the 2.7mm Kolibri, the world's smallest production firearm. He details its blowback action, tiny detachable magazine (typically 5-6 rounds), and unique centerfire ammunition. Despite its size, the Kolibri is noted as being underpowered even for its era, primarily serving as a historical curiosity rather than a practical self-defense tool.

This video explores the compatibility of a 50 BMG cartridge with a 12 gauge flare gun. The experiment reveals that while the cartridge fits, the flare gun's mechanism cannot ignite the tough 50 BMG primers. However, it successfully fires a standard 12 gauge blank, highlighting the difference in primer hardness. The content is presented from a hobbyist perspective, focusing on experimental curiosity rather than professional instruction.

This video from Tática Civil, featuring an expert instructor, explains the dangers of firing upwards due to projectile drop and terminal velocity. It demonstrates the safe use of 9mm shot shells for controlled demonstrations, highlighting the Canik Mete MC9 Prime with a Gideon Valor red dot sight. The instructor emphasizes crucial firearm safety protocols.

This guide details an experimental test to debunk the myth that a .50 BMG round passing near a target can be lethal. Using a ballistic mannequin, cardboard indicators, and a concrete backstop, the test demonstrates that a near miss from a .50 BMG round does not impart enough shockwave or air pressure to cause fatal injury, though the projectile itself possesses immense kinetic energy as evidenced by its impact on the concrete block. The test was conducted objectively by an individual with high authority, indicated by their empirical testing methods and proper safety protocols.

This video explores the surprising functionality of a realistic toy shotgun, the M870 by Dart Armory. The presenter tests if it can chamber and cycle real 12-gauge shotgun shells, comparing its operation to a Mossberg 590. The toy shotgun successfully loads, chambers, and ejects real shells, demonstrating a high degree of realism in its mechanical operation.
