The Walther Model 1 was Carl Walther's first commercial semi-automatic pistol design, chambered in 6.35mm Browning (.25 ACP). A simple pocket pistol with fixed barrel and blowback operation, it established Walther as a pistol manufacturer. The early Walther pocket models (1 through 8) are sought by collectors specializing in early 20th century German semi-automatic pistols and represent the foundation of the Walther legacy.
