This video provides an in-depth analysis of the rare Roth-Sauer automatic pistol, designed by Karel Krnka and manufactured by J.P. Sauer & Sohn. It highlights the pistol's complex long-recoil action, where the bolt and barrel remain locked throughout the cycle. The firing mechanism is noted for its similarity to later designs like the Roth-Steyr 1907 and modern striker-fired pistols such as Glocks, featuring a striker tensioned to half-cock and fully cocked by the trigger pull. The video also discusses the specific 7.65mm Roth-Sauer cartridge, its dimensions, and its similarity to the short 7.65mm Frommer cartridge, with which Roth was also involved. The design is described as being significantly ahead of its time.
