C96 Mauser
7.63×25mm Mauser or 9×19mm or .45 ACP
Produced from 1896 to 1937 with some variants, this very accurate and powerful pistol was the first successful semi-auto used extensively in battle. Later variants were used by German SS units and Luftwaffe dispatch riders in the early part of WW2.
The distinctive handle earned it the nickname "Broomhandle". It came with a standard 10-round magazine although later variants offered a 20 round alternative. It also came standard with a wooden stock that doubles as a holster.
The model shown is the Schnellfeuer with a selective fire button switching between single and fully automatic fire.
