A lightweight, compact, collapsible, and easily concealed pistol. The pistol has a barrel and a handgrip which are pivotally attached to the frame. The barrel is locked to the frame by a barrel lock. Operation of the barrel lock releases the barrel, allowing the barrel to pivot for reloading. In the collapsed position, the handgrip folds to cover the frame and the trigger, which is retracted therein. In the firing position, the handgrip is rotated away from the barrel, and locks in place via grip locks disposed in the frame, and the trigger extends from the frame. The hammer is pivotally attached to the frame. The hammer incorporates a firing pin. A safety located on the hammer retracts the firing pin within the hammer to prevent firing the pistol in the safe position, and extends the firing pin to fire the pistol.
