FP-45 Liberator
The FP-45 was a crude, single-shot pistol designed to be cheaply and quickly mass-produced. It had just 23 largely stamped and turned steel parts that were cheap and easy to manufacture. It fired the .45 ACP pistol cartridge from an unrifled barrel. Due to this limitation, it was intended for short-range use, 1–4 yards (0.91–3.66 m). Its maximum effective range was only about 25 ft (7.6 m).
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; though the intended recipients, irregulars and resistance fighters, rarely kept detailed records due to the inherent risks if the records were captured by the enemy.
It was originally intended as an insurgency weapon to be mass-dropped behind enemy lines to resistance fighters in occupied territory. A resistance fighter was to recover the gun, sneak up on an Axis occupier, kill or incapacitate him, and retrieve his weapons.
