[2] The Sedgley OSS is a single-shot, break-action, smoothbore .38 Special pistol which was designed by Stanley M. Haight for the Office of Naval Intelligence.

It was mounted on the back of a cowhide glove; a long-sleeved coat would usually be worn to hide the weapon.

After being loaded and cocked, the weapon is fired by the shooter making a fist and pressing the trigger against the target's body.

[5] The Sedgley OSS is seen in the Quentin Tarantino World War II alternate history film Inglourious Basterds.

The film centers on elements of the First Special Service Force operating under orders from the OSS dropping behind German lines to conduct a political assassination of Nazi high-command.
