  • Patent number: 9664471
    Abstract: An end cap for a semiautomatic pistol is mounted at the breech end of a slide to maintain the striker assembly in place when subject to inertial loads. The end cap includes a body with a base and a cover. A metal plate is mounted between the base and cover to prevent striker blow-out in the event that a primer is pierced. Flexible, resilient projections extend from the base and engage the slide within a recess, the projections extending transversely to the firing axis to counter inertial forces that might otherwise dislodge the end cap and cause a stoppage.

  • Patent number: 9347726
    Abstract: A firearm is provided according to the present invention. The firearm can be a striker style firearm having a slide. A trigger contacts a sear block at the front of the striker to fire the firearm. The striker then moves rearward with the slide under operation of the recoil spring and then returns forward. A reset plunger engages the striker during the second part of this process to reset the striker. The trigger has a release lever which is allowed to rotate relative to the rest of the trigger when the striker is reset and the sear block moves the release lever to the rotated position. The release lever rotates back to the ready position as the trigger is released. A slide stop is also provided that is held in place under operation of the recoil spring.

  • Patent number: 8572879
    Abstract: A firearm hammer that has its cocking spur attached in a hinged manner that is constantly biased to the closed position. Upon sufficiently applied force, the cocking spur can pivot about the hinge from the closed position to a plurality of open positions, and then due to the constant bias, the cocking spur automatically and rapidly returns to the closed position. In one embodiment, a spring at the hinge causes the constant bias of the cocking spur to the closed position. In the closed position, the cocking spur rests upon the main body of the hammer and is thereby supported to allow the hammer to be cocked. This invention reduces the probability of snagging the hammer on clothing as the firearm is drawn for use. This invention also allows instinctive use of the cocking spur since it is automatically and rapidly returned to the closed position after deviations thereof.

  • Patent number: 8371058
    Abstract: A mechanism for the disassembly of a handgun without triggering, which prevents the consequential accidental firing of a cartridge in the chamber upon triggering. The mechanism including a disassembler, sear catcher lever, sear catcher and a sear catcher spring. The disassembler has an eccentric pin. Rotation of the dissembler moves the sear catcher lever forward. The sear catcher spring pushes the sear catcher which abuts the other end of sear catcher lever. The sear catcher can catch the sear as soon as the sear is pressed downwards around the sear pin by the slide, and it can hold the sear beneath the plane of cocking of the firing pin. At the same time, the sear catcher blocks the firing pin safety lever if the sear catcher lever is in its utmost forward position. That way the cocking of the firing pin is prevented and the triggering is blocked.

    Abstract: A locking system for a firearm is disclosed. A lock has a set state and an unset state, and substantial movement of any one or more fire control group components is inhibited with in the set state. A biometric sensor attachable to a grip of the firearm is receptive to an input biometric feature data set corresponding to a physiological feature of a user. A biometric input controller stores biometric feature data sets corresponding to enrolled user identities in a memory, and compares it against the input biometric feature data set to generate a biometric input validation status indicator signal. A proximity sensor attachable to the grip detects possession of the firearm by the user and generates a corresponding grip detection indicator signal. A system controller selectively actuates the lock to the set state and the unset state based upon a received combination and sequence of the biometric input validation status indicator signal and the grip detection indicator signal.

  • Patent number: 8356437
    Abstract: A firing pin position indicator may be mounted to the breech end of a weapon. The indicator may include a solenoid with a plunger and a firing pin adapter that is selectively engageable with the plunger. The firing pin adapter may be fixed to the firing pin of the weapon. The solenoid plunger may be coupled to a quick-release lock. The quick-release lock may be selectively engageable with the firing pin adapter. The quick-release lock may include a housing and a spring-loaded piston that is translatable in the housing. The quick-release lock housing may be coupled to the solenoid plunger with a pin. A sensor may sense the position of the solenoid plunger and may provide a control signal to the weapon.

  • Patent number: 8276502
    Abstract: This disclosure describes embodiments of an ambidextrous or reversible safety mechanism for firearms. The safety mechanism can be utilized on specific rifles and shotguns, for example an AK47, SAIGA or similar firearms, as a retrofit to reposition the existing safety mechanism to a configuration similar to or nearly identical to an AR15, M16 or similar firearms. In this way, personnel familiar with the safety operation of the AR15 or M16 will be able to operate the retrofit firearm without learning the operation of a new mechanism. Once retrofitted, the firearm safety mechanism will have the same visual appearance, action, and “feel” as the firearm with which they are familiar. The distance from the grip (trigger) to the engagement portion of the safety mechanism of the retrofit firearm will be very similar to that of the familiar firearm.

  • Patent number: 8245427
    Abstract: A firing pin safety catch mechanism for a firearm, especially an auto-loading firearm which operates with a closed action such as found on the United States Military's M16 and its various derivatives. The firearm includes a firing pin which is housed within a bolt carrier group and which is capable of being moved from a rest position in which its proximal end is out of the travel path of the hammer to a firing position. The safety catch mechanism includes a safety catch, a pin and a spring for biasing the safety catch to hold the firing pin in its rest position to prevent the unintentional movement of the firing pin and thereby prevent the unintentional discharge of the host firearm. The safety catch includes a cam surface cooperating with the hammer so that the catch is released from engagement with the firing pin when the hammer has substantially completed its path of travel.

  • Patent number: 8220193
    Abstract: Applicant has disclosed an improved trigger assembly for firearms, and a related method, to avoid premature firing after an unintentional trigger rotation, especially where light trigger pulls have previously been set. In the preferred embodiment, Applicant's trigger assembly has two triggers: a slotted primary trigger and a secondary trigger which can pivot into the slot. During an intentional trigger pull, the shooter's finger initially pushes against the secondary trigger until it pivots and nestles within the primary trigger's slot. Continued pulling on both the secondary and primary triggers causes a hammer to rotate off a sear, thereby allowing the firearm to discharge. In an unintentional trigger rotation, where the secondary trigger is not pulled back enough to nestle within the primary trigger's slot: an upper portion of the secondary trigger (unseen within the housing) constrains a protrusion on a spring-biased mainspring guide.
