A self-defense device with a body, a gun barrel, a trigger assembly, at least one forward light, and a switch is disclosed. The body is held by a human hand. The gun barrel can be positioned in the body and include an entry port and an exit port. The trigger assembly includes a trigger and a firing pin. The firing pin is moveable to engage a round in the barrel. The light can be exposed on an outer surface of the body. The light is positioned such that light emitted by the light projects forward, along the axis of the barrel. The switch can selectively activate and deactivate the light. The switch and the trigger are positioned close to one another so as to be concurrently engageable by a single human hand.

A folding pocket pistol has a frame, a barrel connected to the frame and defining a bore and a chamber and movable between an operating position and a loading position, a bolt connected to the frame and operable to reciprocate between a rearward cocked position and a forward battery position, a trigger connected to the frame and having a lever movable between a forward position and a rearward position, a grip connected to the frame and movable between a closed position abutting the frame, and an open position away from the frame, the grip defining a pocket adapted to receive the trigger lever when the trigger lever is in the forward position, and the grip having a pocket block surface adapted to contact a portion of the trigger lever when the trigger lever is in the rearward position, which prevents the grip moving to the closed position.

A safety pin locks a barrel latch while the firearm discharges a round of ammunition. The barrel latch safety locking mechanism is incorporated into the frame and is actuated by the trigger assembly. The barrel latch safety locking mechanism engages the barrel latch to prevent movement during firing keeping the barrel latch engaged with the barrel. The firearm is further comprised of a slide switch that is connected to the barrel latch that allows a user to disengage the barrel latch for loading.

A barrel has a barrel body that extends a barrel length and a bore extending through the barrel body. The bore has a cartridge chamber section and a rifled section with a bore diameter. A cartridge shell fits within the cartridge chamber section and the projectile extends from the cartridge chamber section into the rifled section. The cartridge shell with the projectile has a shell length within the bore, the barrel length is less than twice the shell length. The rifled section has rifling grooves between rifling lands, and each of the rifling lands has a land width. The groove diameter is greater than the land diameter by an amount that is more than one half of the land width. The barrel body has an extractor assembly with an arm retractably extending from a cavity. The arm can rotate in the cavity when extended and does not rotate when retracted.

A combination of autococking and decocking mechanisms for a single barrel break-open shotgun including a body, a barrel, a trigger and a hammer is provided. The autococking and decocking mechanisms include the autococking mechanism having an autococking lever to place the hammer in a firing position when the barrel is broken open from the body and the decocking mechanism having a decocking lever to selectively place the hammer in the firing position or a decocked position.
