The Sedgley OSS is a single shot, break action .38 Special pistol which was designed by the Naval Intelligence Office. It was meant as a covert operations and assassination weapon. It was mounted on the back of a cowhide glove; the gun would be usually worn along with a long-sleeved coat to hide the weapon until it was used. Due to its appearance, it was commonly nicknamed "Glove Pistol" or "Glove Gun".
The trigger is a bar parallel to and extending past the barrel. After being loaded and cocked, the weapon is fired by pressing the trigger against the target's body.
