7.65mm Radium Pistol
This video delves into the unique Gabilondo y Urresti Radium pistol, a precursor to the Ruby pistol. It highlights the Radium's unusual 7.65mm caliber and its innovative internal magazine loaded via a sliding grip panel. The pistol's production was short-lived, ending around 1915 due to the success of the simpler Ruby pistol in securing a large French military contract.
