MP9 and TP9: A Complete History From Steyr to B&T

This video provides a detailed look at the B&T TP9, comparing it to the MP7 and highlighting its features. It covers the deployment of the folding stock, attachment of a B&T suppressor, and the mounting of a Holosun red dot optic. The unboxing of a KCI USA 30-round magazine and a function check of the laser and light system are also demonstrated, showcasing a complete tactical setup.

This review covers the B&T MP9, highlighting its iconic status and a new 3D-printed titanium suppressor. The new suppressor offers improved performance, reduced weight, and HUB compatibility for broader use on 9mm firearms, retailing at $850. The MP9 itself is shown in a full-auto demonstration, emphasizing its compact and select-fire capabilities.

The B&T TP9 is a compact PDW with a unique niche for discreet firepower in WROL scenarios, but its high price, proprietary suppressor system, and significant trigger flaws limit its appeal. While offering excellent size and ambidextrous controls, its performance is hampered by muzzle rise and a poor trigger, making it unsuitable as a primary rifle.

The B&T TP9 is a Swiss-made 9mm semi-automatic pistol, evolving from the Steyr TMP/SPP and B&T's MP9 SMG. It features a unique rotating barrel locked-breech system, an AR-15 style charging handle, ambidextrous controls, and a proprietary tri-lug muzzle device. The trigger pull is linear, and field stripping is straightforward, revealing the innovative barrel mechanism. The review also touches on NFA trust laws and includes a demonstration of a speed loader.

This video details the history and technical evolution of the B&T MP9/TP9, tracing its origins from a Steyr project. Key improvements by B&T include the addition of a stock and the adoption of a standard Picatinny rail. The firearm's unique rotating barrel, short recoil operation, and innovative bolt manipulation feature using a 9mm cartridge are highlighted.

This video features a review and discussion of the B&T TP9 firearm. The creator questions whether the TP9 is a "legit" or "over-hyped" gun, inviting viewer opinions.

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.
