The Palm Pistol is a firearm specially designed to be easy to use for the elderly or people with limited hand mobility. It fits in the palm and can be used with either hand. The muzzle fits between the first two fingers, and the trigger is pressed with the thumb rather than the index finger, which gives greater firing stability and reduces muzzle drift.The Palm Pistol: Main Site

Previous Palm Pistols
Otherwise known as a turret revolver, firearms designed to be concealed in the palm were first patented in 1882 by Jaques E. Turbiaux in Paris. Original models held seven or ten rounds. The Palm Pistol from Constitution Arms is a single-shot weapon.
In 1883, the Minneapolis Firearms Company produced a palm pistol called the Protector under license from Turbiaux. The protector fired seven rounds.Genitron.com: Turbiaux Palm-Squeezer Pistol
