The belt buckle pistol was an experimental German World War II firearm consisting of two 7.65 mm or .22 long rifle barrels and lockwork concealed within a Nazi Party belt buckle. The barrels were 2" long and the wearer needed to get very close to their victim. A lever was pressed which allowed the spring-loaded buckle to pivot downwards, exposing the barrel. Noted firearms authority S.P. Fjestad claims that they were designed by Louis Marquis while he was in a prisoner of war camp during World War 1 and that less than ten of these guns have been discovered.
