Abstract: A firearm, especially a pistol, having a receiver and a guide rail for a slide that has a barrel, a retaining spring, and a slide stop device, the firearm further including a disassembling lever that is rotatable in the receiver, configured so that when the lever is in one end position: a) an abutment of the slide abuts against the lever and cannot be moved further forward, b) a fully inserted magazine is in contact with the lever and prevents any rotation, and c) an upper surface of the lever lies opposite an edge of the slide. When the magazine is withdrawn and the slide is stopped by the slide stop device, the lever can be rotated to allow the forward movement of the receiver.

Abstract: A delayed rotary blowback mechanism integrated into a firearm bolt and carrier subassembly. A plurality of radial locking lugs are configured at a rear end of the bolt and seat within a mating profile of a barrel extension of the firearm in a fully chambered position. A plurality of chamfered locations are configured between the lugs and a receiving profile in the barrel extension for influencing linear to rotational motion of the bolt. A cam pin extends upwardly from the bolt and seats through a circumferentially directed slot configured within the bolt carrier. Upon initiating of the discharge cycle, signaled by the round traveling through and out the end of the barrel, the chamfered configuration results in the bolt and cam pin rotating within the carrier and the lugs subsequently separating from the barrel extension, with the bolt and associated carrier retaining sufficient inertia to cycle through the discharge cycle to the set position concurrent with reloading a subsequent cartridge.

Abstract: A cocking/de-cocking mechanism for semi-automatic striker-fired pistols having a multi-function cocking lever for controlling, by rotational movement, the cocking or arming of the tiring pin, while effecting de-cocking by the lateral displacement of the cocking lever on its support pin.

Abstract: The present invention relates to a safety device for a firearm with a trigger bar in said firearm. The trigger bar moves in response to a pulling of a trigger. An actuator in said firearm is adapted to actively move said trigger bar between a first position and a second position. The trigger bar engages in the trigger induced movement with a hammer link for releasing a hammer and firing a cartridge bullet when the trigger bar is in the first position or first state. However, said trigger bar does not engage in the trigger induced movement with the hammer link, such that the cartridge bullet is not fired, when the trigger bar is in the second position or state.

Abstract: The invention discloses a safety mechanism of a handgun which depends on a magazine and which prevents the triggering of a handgun when the magazine is removed. Additionally, a mechanism enables handgun disassembly without need for the triggering after the magazine has been removed from the handgun. A safety mechanism is positioned inside the handgun receiver; including a magazine, sear catcher, sear catcher spring, grip safety pin, sear, sear pin, firing pin safety lever and firing pin. When the magazine is inserted into the handgun, the sear catcher is pushed into position in which it cannot block the firing pin safety lever nor catch the sear. When the magazine is removed from the handgun, the sear catcher spring pushes the sear catcher into position in which it blocks the firing chain by blocking the firing pin safety lever.

Abstract: A safety selector for selectively implementing a firing disabled position for the prevention of unintentional firing of a firearm. The safety selector comprises two prongs adapted to push a cross bolt safety actuation lever to the right or to the left. A DC electrical motor provides torque, which is transferred through a torque transferring mechanism, to the safety selector. The safety selector is particularly useful for actuation via remote control.

Abstract: A shotgun includes a forearm and a fastening mechanism that is used to couple the forearm to the remainder of the shotgun. The fastening mechanism moves between a first position where the forearm is coupled to the remainder of the shotgun and a second position where the forearm is uncoupled from the remainder of the shotgun. In one embodiment, the fastening mechanism is a lever-type fastening mechanism. In another embodiment, the fastening mechanism includes an anchor that is shaped to be received in a hole in a magazine of the shotgun. The anchor rotates between a first position where the anchor is unable to exit the hole so that the forearm is coupled to the magazine and a second position where the anchor is able to exit the hole so that the forearm is uncoupled from the magazine.

Abstract: Safety apparatus for firearms are described. An example safety apparatus may be used with a firearm having a latch movable between a first position to retain a breech of the firearm and a second position to enable movement of the breech. The safety apparatus includes a biased safety mechanism coupled to the latch and movable between the first position and the second position. Additionally, the safety apparatus includes a safety device moveable between a locking position and a non-locking position. The safety device interacts with the biased safety mechanism when the safety device is in the locking position and the safety mechanism is in the first position to enable the biased safety mechanism to prevent a trigger force from moving the latch to the second position but to enable the latch to be deflected by a returning breech.

Abstract: A firearm fire control assembly for disposition in a forwardly placed support-hand operative relationship within a firearm having a combination of a firing pin and a firearm hammer adapted to engage and fire a cartridge, a sear assembly to alternately engage and disengage the combination of the firearm hammer and firing pin, and a trigger assembly including a movable trigger mechanism that is operable to engage the sear assembly to cause the firearm hammer firing pin combination to fire the firearm, a fire control assembly including a fire control depression member and a fire control rod operably connected to the depression member, and being positioned in a forward disposition disposed within a forestock of the firearm, and the depression member adapted to be operably engaged and depressed by the user's conventional forwardly placed support hand to maneuver the fire control rod to provide firing control of the firing of the firearm.

Abstract: A closed bolt system with a trigger assembly for converting an open bolt, blowback type submachine gun into a single firing carbine is provided. The closed bolt system with trigger assembly includes a tensioned trigger member supporting a tensioned disconnector system. A tensioned sear interacts with the disconnector system and a tensioned hammer. The hammer strikes a firing pin in the bolt when it is released from the sear. The blowback of the bolt, as a result of expanding gases from the exploding and exiting round, re-cocks the hammer by re-engaging the sear with the hammer and disengages the sear from the disconnector system. Only after releasing the trigger will the sear re-engage with the disconnector system and thereby permit another round to be fired. A receiver having a cavity encloses the bolt and prohibits a fully automatic bolt to be used therewith.

Abstract: An inertia-resistant preventer mechanism is provided for use in a firearm safety enhancement system to reliably and selectably prevent or to unblock a firing mechanism of a firearm. The inertia-resistant preventer mechanism includes a first solenoid having a moveable blocking rod with a first actuation response speed. The blocking rod is normally interposed in the firearm to prevent activation of the firing mechanism and is selectably activated to unblock the firing mechanism. A second solenoid is also included, having a second blocking rod with a second actuation response speed equal to or faster than the response speed of the first solenoid. The second blocking rod of the second solenoid is normally interposed at an angle to the first solenoid to block the first blocking rod of the first solenoid against accidental unblocking caused by inertia and relative movement of the firearm.

Abstract: A semi-automatic pistol has a slide which houses a barrel and a firing pin, and a frame which houses a trigger and a mechanism for releasing the firing pin. The mechanism includes a sear engageable with the firing pin and a cam actuator which is operable by the trigger. The cam actuator prevents movement of the sear to release the firing pin and also operates a detent to prevent movement of the firing pin, until the trigger has moved the cam actuator by a predetermined amount. The firing pin can also be locked in position by a safety catch which can act at the same time on a linkage between the trigger and the cam actuator, to disconnect the latter from the trigger. The operating characteristics of the trigger may be determined by selection of an actuator having a required profile. The firing pin is held captive in the slide and cannot be tampered with.

Abstract: A fire control assembly (400) is provided with increased safety features. A set porch (470) is formed on a disconnect (404) to hold a firing window (416) of the disconnect (404) out of contact with a sear pin (412). A pin (458) engages a safety surface (460) on the disconnect (404) to hold the disconnect (404) in a direction (494) until the firing window (416) passes under the sear pin (412) and the sear pin (412) engages the set porch (470). Once the sear pin (412) is on the set porch (470), the trigger (402) must be pulled to engage the sear pin (412) with the firing window (416).
