A barreled firearm having a mass-locked breechblock and a recoil-damping element which is connected on one side to a frame assembly and on another side to a barrel assembly including a barrel. A housing part of the barrel assembly is mounted in the frame assembly in an axially slidable manner. A support element stationary relative to the barrel is mounted in a breechblock housing or in the frame assembly in an axially slidable manner. Alternatively, a support element stationary relative to the frame assembly is mounted in a breechblock housing in an axially slidable manner. The breechblock housing is guided by the frame assembly in an axially slidable manner and the breechblock housing is supported by the support element by means of a spring element. This design absorbs or reduces recoil when a shot is fired from the barreled firearm.

An apparatus and method for modifying a handgun to accept an optical sight comprises a modified slide mechanism adapted to include a flat recessed rear section configured to receive an adapter plate for mounting an optical sight. Various embodiments of the adapter include modified internal components used to replace stock components what will no longer fit within the modified profile of the slide mechanism. Replacement of the slide mechanism and associated internal components will allow a user to add an optical sight to an existing handgun.

A recoil-operated pistol has an arrangement which lowers the barrel bore axis and reduces the effect of felt recoil on the user. The pistol has a frame having a handgrip adapted to receive a magazine and a slide mounted for alternating longitudinal movement. A barrel carrier is mounted for alternating longitudinal horizontal movement along the frame and has a barrel rotatably connected to it near its muzzle end. The axis of the barrel bore when in the position for firing is below the lips of the magazine. An actuating mechanism under the influence of the recoiling barrel carrier rotates the barrel upwards such that the breech end of the barrel moves upwards to allow a cartridge to be removed. The recoiling barrel carrier urges the slide rearwards to facilitate the extraction and feeding of cartridges.

The present invention relates to a gun (1) with a pair of barrels (6′, 6″) flanking each other, each delimiting a cartridge chamber (12′, 12″). The gun further comprises a pair of firing pin tips (8′, 8″) for a cartridge (10′, 10″), movable towards the cartridge chambers (12′, 12″) by means of a firing device operated by a trigger (4′, 4″); such device acts on the firing pin tips to allow a substantially simultaneous advancement thereof. The invention also relates to a two row magazine for a double barrelled gun.

A magazine is provided for a firearm. The magazine comprises a locking mechanism. The locking mechanism has a user interface adapted to enable a user to select between a locked condition and an unlocked condition. The locking mechanism has a rotor movable between a first rotational position when the locking mechanism is in the locked condition and a second rotational position when the locking mechanism is in the unlocked condition. The magazine comprises an elongated shaft connected to the rotor. The magazine comprises a block element connected to the elongated shaft. The block element is adapted to move between a first position when the locking mechanism is in the locked condition in which at least one of firearm operation and magazine extraction are prevented, and a second position when the locking mechanism is in the unlocked condition in which firearm operation and magazine extraction are enabled.

Various embodiments for an angled action firearm that counteracts muzzle rise are described. The angled action firearm includes a receiver having a first receiver end and a second receiver end. The receiver has a top surface sloping upwards from the first receiver end to the second receiver end. The angled action firearm further includes a slide moveably coupled to the receiver having a bottom surface opposite that of the top surface of the receiver. The slide has a first slide end and a second slide end, where the angled bottom surface of the slide slopes upward from the first slide end to the second slide end. The angled action of the slide causes downward pressure during recoil counteracting muzzle rise.
