The Walther TP and TPH handguns are extremely compact double-action lightweight semi-automatic pistols in .22 Long Rifle and .25 ACP calibers.

Unlike the Walther TP, with its open-top slide, the TPH has an enclosed breech with an ejection window.

The extractor is an L-shaped piece of steel which is spring supported and positioned in a groove on the right side of the frame beside the striker.

The one-piece firing pin and the striker spring protrude through the safety arbor and are held in position by it.

There is a break-trough on the left side of the slide where the safety lever, which is fixed to the arbor, is positioned.
