Evolution of the Submachine Gun: Three Distinct Generations

This review ranks the top 5 submachine guns, highlighting the MP40's superiority over the Thompson due to weight and ergonomics. The Walther MPL is noted for its unique forward assist, while the Uzi is praised for its compact design and safety features. The HK MP5 is crowned the 'King of SMGs' for its accuracy via a closed-bolt, roller-delayed blowback system. Honorable mentions include the MK760 and the high-rate-of-fire Mac-10.

The MP-18,I is recognized as the first submachine gun to see combat, developed by Germany in late 1915 for trench clearing. It features a simple open-bolt, blowback-operated mechanism with full-auto fire only, lacking a disconnector. The design includes a Trommel magazine with a sleeve to prevent over-insertion, and early models bear distinct markings like 'M.P. 18,I.' and the year of manufacture.

This video compares a suppressed Thompson M1A1 prototype with the Sten Mk.IIS, detailing the Thompson's unique suppressor design and modifications. Despite comparable muzzle noise, the Thompson's significantly louder mechanical action and heavier, longer profile led to its abandonment in favor of the M3 Grease Gun in 1944 trials.

The M3 Grease Gun's magazine design was driven by its mass-production, low-cost philosophy, mirroring the British Sten gun. Unlike the Thompson's complex T-lug system requiring milled receivers, the M3 used a simpler single-feed magazine compatible with its stamped sheet metal construction. This design choice prioritized manufacturing efficiency over inter-operability with existing Thompson magazines.

The Hyde/Marlin M2 SMG was a rare WWII firearm designed by George Hyde to be more accurate and controllable than the Thompson. Despite superior performance in trials, manufacturing issues with metal sintering and the development of the cheaper M3 Grease Gun led to its cancellation. Only 400 M2s were produced, making it a forgotten rarity in firearm history.

This video, "Apache Arms Carbine: A Saga of Compliance and Crappy Manufacture," delves into a firearm with a title that suggests a focus on its compliance with regulations and potential manufacturing flaws. The description includes hashtags related to forgotten weapons, the Apache brand, Thompson firearms, the National Firearms Act (NFA), machine guns, and semi-automatic function, along with gunsmithing. This indicates a review or discussion likely highlighting the challenges of manufacturing compliant firearms and potentially comparing them to other iconic models like the Thompson.

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.
