The Parabellum pistol was adopted by the German Navy in 1904 and later by the German Army in 1908.
This gun was supplied to the German army until 1942, and was used by various countries until the middle of the twentieth century.
The Gletcher replica of PO8 Parabellum is a full blowback and has a full drop-out metal magazine that holds the CO2 and 21 BBs.
The blowback action is just like the real pistol, with the top toggle pulling up and back over the pistol.
Bristol Airguns opinion, an iconic pistol, well made and worth a look, certainly a definite for any WWI or WWII collector.
