Also known as: Frank Wesson Tip-Up Derringer, Frank Wesson Single Shot Pocket Pistol

Overview

The Frank Wesson Pocket Pistol is a single-shot, spur-trigger pocket pistol chambered in .22 rimfire, produced by gunmaker Frank Wesson from the mid-1860s. It uses a spring-loaded tip-up barrel that pivots upward for loading when a lever beneath the action is released and the hammer is set at half-cock. With a roughly 3.5-inch barrel and a brass frame, it was marketed as a compact, easily concealable defensive arm during the American rimfire pistol boom that followed the Civil War.
