The Model 2 Pen Pistol features a stainless steel barrel and frame with a brushed finish, built into a pen-shaped tubular body complete with a pocket clip. It is designed to fold into an L-shaped configuration for firing, exposing a small trigger when deployed.
Chambered in .25 ACP (6.35mm), this single-shot design uses a front-loading, one-round chamber. Loading is accomplished by unscrewing the knurled front cap, inserting a cartridge, and reattaching the cap, making operation simple and direct.
The 2-inch stainless steel barrel and absence of sights keep the profile clean and minimal, consistent with the pen-style form factor. The brushed stainless finish complements the utilitarian design and resists wear.
This discontinued U.S.-made model carries a PP-prefix serial, associated with the Model 2 Pen Pistol series. It stands out as a specialized derringer variant that showcases American Derringer’s compact, all-steel construction approach.
