About

What it is, and why it matters

Copy a link to this section

The Blunt & Syms Pepperbox is a six-shot, double-action percussion pepperbox pistol sold by the New York firm of Orison Blunt and John G. Syms between roughly 1837 and the 1850s. Built around a rotating cluster of .31 caliber smoothbore barrels rather than a single bored cylinder, it uses an underhammer mechanism in which the hammer strikes a percussion cap on the bottom barrel, and a ring trigger that both rotates the barrel group and cocks the action with each pull. The streamlined underhammer layout, with a small shield to protect the shooter's hand from cap fragments, made it a popular concealable self-defense arm before the rise of the cartridge revolver.

Pepperboxes like the Blunt & Syms were the everyday concealed-carry pistols of the 1840s and 1850s, valued for delivering multiple shots before the single-barrel cap-and-ball revolver and metallic cartridge displaced them.

Made in small, medium, and large frame sizes; many examples are unmarked, while marked guns carry 'BLUNT & SYMS / NEW YORK' on the frame. Orison Blunt received U.S. patent 6,966 (25 December 1849) covering an underhammer pepperbox design.
