FROM WIKIPEDIA
The FP-45 Liberator is a handgun manufactured by the United States military during World War II for use by resistance forces in occupied territories. The Liberator was never issued to American or other Allied troops, and there are few documented instances of the weapon being used for its intended purpose; this was compounded by the intended recipients – irregulars and resistance fighters – rarely keeping detailed records due to the inherent risks if the records were captured by the enemy. Few FP-45 pistols were distributed as intended, and most were destroyed by Allied forces after the war.
