A valve sleeve for a CT40-type cannon that functions in association with a detonation assembly to activate a firing pin. The valve sleeve incorporates a receiver to ensure the mechanical support of the cannon's firing pin during firing events, the firing pin being coupled to the valve sleeve and translatable in relation to it, the receiver being constituted by a cylindrical firing pin sleeve, a firing pin valve, and a firing pin assembly inserted in the substantially cylindrical sleeve and the firing pin being inserted both in the valve and in the firing pin assembly, this receiver being revolving.

A firearm with manually operated bolt release includes a receiver defining a longitudinally-extending cavity, a barrel, and a bolt slideably mounted in the receiver for reciprocating axial movement between a forward closed breech position in battery with the barrel and a rearward open breech position. A recoil spring biases the bolt forward towards the closed breech position. A manually actuated bolt release is pivotably mounted in the firearm and movable between an engaged position and a disengaged position. The bolt release includes a locking portion configured to selectively engage a locking recess formed on the bolt for holding the bolt in the open breech position, and disengage the locking recess for releasing the bolt to reclose the breech. In one embodiment, the bolt may be automatically disengaged from the bolt release by retracting the bolt a second time.

A handgun which vertically displaces a magazine and cocks and snaps a hammer so as to fire a bullet out of the magazine once a trigger handle has been displaced from a first position to a second position. The handgun is made up of a body, a trigger handle, a barrel, and a magazine. A magazine lift mechanism is disposed in the body and functions to vertically displace the magazine upon displacement of the trigger handle. A firing mechanism is disposed in the body, trigger handle, and barrel of the handgun and functions to fire bullets in the magazine upon displacement of the trigger handle. A trigger force mechanism is disposed in the trigger handle and provides a force against which the trigger handle is displaced. The trigger force mechanism returns the trigger handle to the first position when the trigger handle is released from the second position.
