About the Pedersoli Derringer Guardian

The Pedersoli Derringer Guardian is a single-shot, muzzle-loading percussion pocket pistol built by Davide Pedersoli in Italy. It is a diminutive 4.5 mm caplock derringer with an 80 mm rifled barrel and an external hammer, styled after the concealable single-shot pocket pistols of the 19th century. The standard model uses a traditional nipple for #11 percussion caps, while a separate version is set up for #209 shotshell primers.

Small enough to vanish into a coat pocket, the Guardian revives the classic gambler's derringer as a working caplock: a single 4.5 mm ball loaded from the muzzle and fired by a percussion cap on an exposed nipple.
