Walther Model 8

The Walther Model 8 was a 6.35mm single-action pocket pistol manufactured by Carl Walther GmbH between 1920 and 1940. It was fed by an 8-round magazine and chambered in .25 ACP. The Model 8 is a blowback pistol with a concealed hammer and has several design features that were innovative for Walther, including fewer parts and an easier disassembly.
The Model 8 was produced at the about same time as the smaller and less popular Walther Model 9.
