The Walther TP and TPH handguns are extremely compact double-action lightweight semi-automatic pistols in .22 Long Rifle and .25 ACP calibers. Pistols in this size range are sometimes referred to as pocket pistols, or Taschen Pistolen in German (TPH stands for the Taschen Pistole, Hahn, or "pocket pistol, hammer" variant). The TP was produced by Walther from 1961-1971 and the improved TPH has been produced continuously since 1968. Models have been produced in Germany and (by Interarms) in the US.
