derringer

A type of very small, concealable pistol with one or two barrels, but without any loading system or magazine.

“Afraid? Oh no! they never interfere with me. […] And look here,” and diving her little hand into the bodice of her dress she produced a double-barrelled nickel-plated Derringer, “I always carry that loaded, and if anybody tried to touch me I should shoot him[…]”

Alternative form of derringer (“pistol”).
