The physible Liberator's release to the Internet can be understood as Defense Distributed's attempt to more successfully execute the historical psychological operation, and as a symbolic act supporting resistance to world governments. However, though used in France, there is little proof that the pistols were ever dropped into occupied Europe in large quantities. Occupying forces in Europe would have to weigh evidence of distributed pistols as a factor in planning against civilian resistance, which would complicate their strategy and affect morale. A project of the OSS (which would later become the CIA), it is thought the Liberator was equally purposed as a tool of psychological warfare. The OSS intended to air drop the gun into occupied Europe for resistance forces to use. The pistol is named after the FP-45 Liberator, a single-shot pistol that George Hyde designed and that the Inland Manufacturing Division of the General Motors Corporation mass-produced for the United States Office of Strategic Services (OSS) in World War II. President Joe Biden announced in early April that the Justice Department would issue new rules for ghost guns within 30 days. On April 27, 2021, the United States Court of Appeals for the Ninth Circuit vacated the injunction and ordered the district court to dismiss the case, holding that Congress had expressly prohibited judicial review of the agency decisions in question. On the same day the tweet was posted, a federal judge stopped the release of blueprints to make the Liberator due to it being an untraceable and undetectable 3D-printed plastic gun, citing safety concerns. Already spoke to NRA, doesn’t seem to make much sense!” On JPresident of the United States Donald Trump posted on Twitter about the decision to allow the online publication of the Liberator's files: “I am looking into 3-D Plastic Guns being sold to the public. On Jthe United States Department of Justice reached a settlement with Defense Distributed, allowing the sale of plans for 3D-printed firearms online, beginning August 1, 2018. The plans for the gun remain hosted across the Internet and are available at file sharing websites like The Pirate Bay and GitHub. The plans were downloaded over 100,000 times in the two days before the United States Department of State demanded that Defense Distributed retract the plans. The open source firm Defense Distributed designed the gun and released the plans on the Internet on May 6, 2013.

The Liberator is a 3D-printable single shot handgun, the first such printable firearm design made widely available online. For the shotgun, see Winchester Liberator.
