In Search of Hard Currency: Prototype 9x19mm vz52 Pistol

The Cordova Estandar is Colombia's domestic service pistol, developed by Indumil starting around 2009-2010 and entering production in 2014. It features a polymer frame, hammer-fired action with a Browning tilting barrel, and a modular fire control unit. Design influences from the IWI Jericho and Beretta are evident, with shared manufacturing processes and materials with the Galil rifle.

The 6.5x25mm CBJ cartridge offers significant armor-piercing capabilities, even outperforming standard rifle rounds against hardened steel. It achieves this by utilizing a small, high-velocity tungsten penetrator within a sabot, scaled down from tank ammunition technology. The cartridge is designed for easy conversion of existing 9x19mm platforms like the Glock and MP5 with just a barrel change, maintaining compatibility with standard magazines and bolts.

The Rideout Arsenal Dragon pistol features a unique lever-delayed blowback system designed to reduce recoil by lowering the bore axis. This design aims for a linear impulse, minimizing muzzle flip. It also incorporates ambidextrous controls and a 1911-style sliding trigger for enhanced ergonomics and safety.

The Full Conceal M3D, a folding Glock 19, aimed to solve deep concealment issues by mimicking a smartphone profile. Despite a mechanically sound design with a protected trigger when folded, the $1,000 MSRP and production costs led to the company's bankruptcy. It performed adequately in a backup gun match, finishing 8th out of 39.

The Glock G45 Gen 6 represents a significant evolution, blending the G17's full-size grip with the G19's compact slide. This review highlights key enhancements including an improved recoil system for faster return to battery, a more aggressive grip texture, and an updated Modular Optic System (MOS) with polymer adapter plates. The Gen 6 also features a factory flat-faced trigger and reduced weight compared to its predecessor, making it a highly popular and shootable option.

This review unboxes the new Glock 45 Gen 6, highlighting its hybrid design combining a G17 grip with a G19 slide. Key Gen 6 updates include enhanced grip texture, a flared magwell, rounded beaver tail, and a trigger guard undercut. The speaker notes the improved ergonomics, a 5.5 lb trigger pull, and the MOS-ready slide, with an MSRP around $700.

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.
