Overview

The National Arms Derringer is a single-shot .41 rimfire pocket pistol built by the National Arms Company of Brooklyn, New York on Daniel Moore's patent. It uses a side-swinging barrel released by a button on the right side of the frame, an exposed hammer, and a spur trigger, and was one of the first large-caliber metallic-cartridge derringers. When Colt acquired National Arms in 1870, it continued the identical design as the Colt Deringer No. 1 and No. 2.
