Some other OSS weapons of note:

Sedgley .38 glove gun, single shot, fired by squeezing the body while the barrel stuck out between the middle two fingers.

A .22 single shot Stinger that was extremely compact.

The most popular was a modified HiStandard HDM .22 with a long silencer that was a great assignation weapon.

Interesting is that a followup to the Liberator was made by the CIA for use in Vietnam. Called the Deer Gun, it was aluminum, used a 9mmx19 round, and had a plastic clip that functioned as a safety until ready to use and then became the sight. The barrel unscrewed to load and once again, used a rod to eject the cartridge case. 1000 were made at a cost of $3.95 and again, they were never used.
