Q&A #38: Short-recoil SMGs and Kimber Model 1907 .45s

This video delves into the original Ingram M10 and M11 submachine guns manufactured by Powder Springs, clarifying common nomenclature errors like 'MAC-10'. It details the unique serial number system, where the first digit indicates caliber (.45, 9mm, .380) and the second denotes the 1970s production year. The function of the manual safety and select-fire switch, along with the internal mechanics of the sear and disconnector for semi-auto and full-auto fire, are explained.

This video demonstrates the HK UMP-45, known as the Striker 45 in MW2, showcasing its handling, loading with .45 ACP rounds, and live fire performance. It highlights rapid fire capabilities, tactical reloads, and the weapon's ergonomics, featuring an EOTech sight and vertical foregrip. The demonstration emphasizes proficient weapon manipulation and safe handling practices.

This video demonstrates the manual of arms for the M1A1 Thompson SMG, focusing on proper loading procedures and safe handling. It features a live-fire demonstration showcasing the firearm's performance in semi-automatic and full-automatic modes, highlighting recoil management and the open-bolt cycling. The content emphasizes the historical significance and operational aspects of this iconic World War 2 firearm.

This video showcases unique Finnish gun posters featuring iconic firearms like the Suomi KP/-31, AK variants, and Mosin-Nagant rifles. It highlights a Kickstarter campaign for a project called 'Forged in Snow,' suggesting a connection to Finnish design or history related to these firearms. The content appears to be visual and promotional, focusing on collectible art pieces for firearm enthusiasts.

The FNAB-43 is a unique Italian submachine gun from late WWII, featuring a compact design with a folding magazine well and a delayed blowback action. It utilizes a closed-bolt system with separate selectors for safe/fire and semi/full-auto modes. While not widely adopted, its innovative mechanisms offer insight into firearm development during the era.

This video features retired Master Sergeant John Keene, an NFA expert for Morphy's and a machine gun collector, discussing various aspects of machine gun lore, collecting, and history. The Q&A covers selling transferable SMGs, post-WWII German small arms engineers, the viability of the T24 (American MG42), market pricing of machine guns, potential popularity of new models if the NFA registry reopened, the effectiveness of open bolt systems on crew-served weapons, recommendations for a first machine gun, the legality and modification of Colt Balloon Guns, historical ownership requirements for Thompsons, the design merits of the MG42, the M1919A6's effectiveness as a squad automatic, significant machine gun improvements, the practicality of variable rates of fire, current machine gun collecting trends, the impact of Knob Creek's closure, and problematic feed systems. The discussion is based on patron questions.

This video details the unique 'French Finger Trap' issue with the MAS-36 rifle's bayonet, where two rifles can become unintentionally locked together. A 1951 French arsenal memorandum identified this problem, proposing a simple modification to the bayonet handle. Drilling a small hole allows a tool, like a firing pin, to depress the internal spring, enabling the separation of locked rifles.

The M134 Minigun is a scaled-down 7.62 NATO rotary cannon, requiring 24V DC power and consuming 1.5 kW. Its high rate of fire (3,000+ RPM) is essential for aircraft engagement windows. The complex delinker mechanism is critical for feeding ammunition, and practical hand-held use is impossible due to weight and recoil. Live fire demonstrates rapid ammunition consumption and the need for indirect aiming.

The H&K G11 is a revolutionary prototype assault rifle designed in the late 20th century, notable for its caseless ammunition and unique rotating drum bolt mechanism. Despite advanced features like a 2000 RPM burst fire rate and integrated optics, its development was ultimately halted by geopolitical shifts and cost concerns.

This video demonstrates the assembly and live-fire of the German 1936 pattern light mortar (L.Gr.W.36). It highlights the mortar's leveling mechanism for accuracy and the difficulty in visually tracking its 50mm projectiles after firing. The content showcases historical military hardware and its operational use.
