This video delves into the innovative Glock 46, a pistol that marks a significant departure from Glock's traditional design. It features a unique short recoil, rotating barrel system and a novel striker disconnect, designed to meet stringent German police requirements for safe disassembly without dry firing. The video explains how these features, along with a modified trigger mechanism and a new disassembly lever, ensure compliance with German federal standards. It also touches upon the specific trigger pull requirements and discusses why this rotating barrel system might have been chosen despite not being a mandatory requirement. The Glock 46 is noted as being exclusively for police agencies, with limited availability outside of specific contracts, and unlikely to be seen in the US civilian market. The presenter highlights attending EnForceTac 2024 for access to the pistol.
This video explores a rare French firearm prototype, the MAT 1955, a short-recoil, tilting bolt, gear-ratio-delayed rifle. Developed as a potential improvement for the MAS 1949, it chambered the 7.5x54mm cartridge and utilized 20-round detachable magazines. The video details its open-bolt firing mechanism and a later iteration in 1956 that reduced weight by incorporating aluminum. Despite its innovative design, the rifle was ultimately unsuccessful and not adopted by the French Army. The presentation acknowledges a correction regarding the gear ratio's function, clarifying its role in bolt acceleration for reliable cycling, drawing parallels to systems in the Browning M1917/1919 and Lahti L35.
This video explores the Kordun pistol, a unique double-stack Tokarev-chambered firearm developed in Yugoslavia by Marko Vukovic. Designed in 1985 for the Yugoslav Peoples' Army as a softer-shooting and higher-capacity alternative to the standard M57 Tokarev, the Kordun features a short recoil, flapper-locked action. Despite its pleasant shooting characteristics, it was ultimately rejected due to its complexity and difficult disassembly. The video highlights the Kordun's historical significance as an early design from a key figure in Croatian firearm manufacturing (IM Metal and later HS Produkt) and showcases a prototype.
This video delves into the Walther Prototype MP, a crucial transitional pistol developed between the PP/PPK and the iconic P38. Focusing on the second "MP" design, the presenter highlights its exposed barrel (similar to the P38) and fixed barrel (like the PP), along with a unique locking system blending Pedersen and tilting bolt short recoil elements. The discussion also touches upon its single recoil spring and its eventual evolution into the P38, noting the scarcity of surviving examples of this specific prototype.
This video examines Captain Carl Pelo's 1954 prototype semi-automatic rifle, developed by Sako. The design features a short recoil mechanism with locking flaps, similar to Degtyarev machine guns. Pelo attempted to market his rifle to Finnish, British, and Swedish forces without success, primarily due to procurement issues and Finland's eventual adoption of the 7.62x39mm cartridge, rendering his design obsolete. Despite performing well in Finnish trials, it was rejected. The video showcases a rare surviving example from Sako's factory museum.
This "From the Vault" video explores the rare Johnson Model 1941 light machine gun, a potential successor to the Browning BAR. Hosted by Brownells Gun Techs Keith Ford and Steve Ostrem, the segment delves into the design's innovative features like its short-recoil system, rotating bolt, and selectable fire rates (200-600 RPM). While noting its advanced design for the era, including an easily replaceable barrel and open bolt firing in full-auto for cooling, the video also highlights its drawbacks: an awkward side-feeding 20-round magazine and significant recoil. Approximately 9,200 units were produced, seeing service mainly in the South Pacific. Ultimately, despite its fascinating place in firearms history, the Model 1941 did not surpass the BAR in overall utility.
This video from Forgotten Weapons explains the roller locking mechanism, differentiating it from roller-delayed blowback. It highlights that roller locking is a sub-type of flapper locking and is notably used in the MG42 and the Czech vz.52 pistol. The system utilizes rollers to secure the bolt and barrel during firing, relying on an external mechanism like short recoil for unlocking and cycling. The description also includes links to the channel's Patreon, Floatplane, and merchandise store.
This video covers the LWRCI SMG-45, a pistol-caliber carbine, showcased at SHOT Show 2020. The description highlights its development around UMP magazines, .45 ACP caliber, and its design leveraging LWRCI's AR platform experience with a unique operating system. The SMG-45 aims to be a "Step-Up" PCC with innovative features and ergonomics.
This YouTube video, titled 'long recoil v short slo mo' and described as 'Long vs Short recoil operation, Anvil 71', focuses on a technical comparison of two firearm operating systems: long recoil and short recoil. The content likely delves into the mechanics and performance differences between these systems, presented in slow motion for detailed observation. The mention of 'Anvil 71' suggests a specific context or demonstration setup. The video aims to educate viewers on these distinct firearm actions.
This video delves into the mechanical operation of Portugal's M938 Light Machine Gun, also known as the MG-13. The MG-13 was an interim German machine gun from the 1930s, designed to be perceived as a WWI-era weapon. The video highlights its closed-bolt, magazine-fed, short recoil, and hammer-fired mechanism. It also showcases unique features such as an adjustable recoil spring tension and a folding stock. The M938 is fed by 25-round box magazines and 75-round double drums. The focus is on the gun's internal workings rather than its developmental history.
This video breaks down the fundamental differences between operating systems and locking systems in firearms. The locking system is responsible for sealing the breech during firing, employing mechanisms like tilting bolts, rotating bolts, and roller locking. The operating system, on the other hand, handles the unlocking process after firing when internal pressure has safely decreased, utilizing systems such as long and short gas pistons or long and short recoil. Blowback mechanisms are presented as a unique case where a single system uses inertia for both locking and unlocking. The video aims to educate viewers on these core mechanical principles for a better understanding of how firearms function.
This video delves into the history and design of Paul Mauser's C98 semiautomatic rifle project, a lifelong endeavor to create a reliable and durable firearm for the German military. The description highlights Mauser's iterative design process, focusing on a flapper-locked, short recoil system. It poignantly recounts a significant event where an out-of-battery detonation during a firing test in 1901 resulted in Mauser losing a finger and an eye, underscoring the inherent dangers in early self-loading firearm development and influencing his later designs to prioritize safety.
