Quad Derringer

QUAD DERRINGER PISTOL. (See also, PISTOL) A four-shot palm pistol, the Derringer is easy to carry and often considered more tool than weapon. A Derringer is generally defined as the smallest usable handgun for any given caliber of ammunition. Though the original design was for a single-shot, single-barrel firearm, this particular variation quadruples the weapon's firing power without adding significantly to its weight

The term "derringer"is actually a misspelling of the last name of Henry Deringer, a manufacturer of small pistols. The gun was so popular that it was often copied, and the name has become the common term for any small firearm. Though easy to carry, it is not an offensive weapon as its shot is quickly spent, it is slow to reload, and it is accurate only in close range.
