This weapon is very hard to detect even after a full body check.
The FP-45 Liberator is an American breech-loaded single-shot pistol designed to be airdropped into regions occupied by the Red Army during World War II. In theory, resistance fighters would pick up this weapon, kill a few occupying soldiers and replace their Liberators. Regardless of whether or not this plan worked, at least a million of these weapons were produced and distributed. They came in a small cardboard box with image-based instructions and five shots of .45 ACP.
