An ejector mechanism for a firearm includes an ejector disposed at a forward face of a bolt. The ejector includes a hole designed to provide clearance for the firing pin to pass at least partially through the ejector. The hole may include a counterbore on a rear side of the ejector.

A pocket pistol having at least one barrel in alignment with at least one associated chamber for receiving a firearm cartridge; a barrel release trigger; a double-action firing trigger; and a frame carrying the at least one barrel, the barrel release trigger, and the firing trigger, and defining a cavity within the frame carrying a hammer set and a firing pin.

A recoilless firearm apparatus for firing at least one bullet of a respective standard cartridge, including a front barrel, a disposable firing activator and a rear discharge opening formed behind the front barrel and aligned with the longitudinal axis of the front barrel. The standard cartridge further includes a casing having an external diameter that is smaller than the rear cartridge-chamber diameter, wherein the casing encloses a sealed inner-casing space that contains gunpowder, and wherein the casing includes a primer. Upon activating the primer, the primer explodes to thereby detonate the gunpowder, forming propellant gasses inside the cartridge that are directed both forward and backward as follows: a) forward: firing of the bullet via the front barrel; and b) backward: pushing, by a recoil force F.sub.p, the casing, being a counterweight to the bullet, to thereby eject the casing from the firearm apparatus via the rear discharge opening.

The present invention relates to a pistol comprising a firing pin safety device integrated into a slide (5) of the pistol comprising a firing pin (1) comprising a lateral extension (25) comprising at least one safety lug (10,11) and a firing pin butterfly safety (2) positioned on an axis of rotation (27) fastened to the slide and parallel to the axis of translation of the firing pin (20), said butterfly safety (2) being able to rotate in a vertical plane between a firing position and a blocking position, said butterfly (2) comprising at least one bearing surface (17,18) on which the at least one lug (10,11) rests when said butterfly is in the blocking position and at least one recess (14) able to allow the at least one lug (10,11) to pass when said butterfly is in the shooting position, the center of mass of said butterfly (2) being on its axis of rotation (27) and the axis of rotation (27) being a main axis of inertia of said butterfly (2).

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.

Adjustability of trigger pull force is enable by the use of a spring interfacing with a trigger shoe counterweight. The spring force is adjustable by use of a set screw interfacing with the spring. A pivot arm member acts between a trigger shoe counterweight and a firing pin release arm to fix the ratio of trigger shoe pull force and firing pin release arm force.

A configurable blowback bolt system is provided. Embodiments include a two-part configurable bolt assembly having a bolt carrier and a configurable bolt that allows for use with various calibers of ammunition, both rifle and pistol. The configurable bolt may also eject cartridges to the right or left side of the rifle by moving the extractor to one or the other side of the bolt. A buffer may be included as part of the configurable blowback bolt to shorten the stroke based on the caliber of ammunition being fired with the configurable blowback bolt system.

A hammer assembly of the automatic mechanism of a firearm, comprising a breech (4) that is pushed towards the barrel (3) by a return spring (6). On the breech (4) and/or in the breech case (3) a hammer carrier (10) is arranged in a sliding way that is pushed towards the breech by a striking spring (13). The hammer carrier (10) carries a hammer (11). The hammer (11) is arranged on the hammer carrier (10) movably between the front end position and the rear end position wherein between the front and rear end positions of the hammer (11), there is a play (F). The hammer (11) is pushed to the front end position by the hammer spring (12).
