A method for sear engagement adjustment of a firearm trigger mechanism by installing a sear control device comprised of a compression spring of a given wire diameter or tube of a given wall thickness over a sear stop pin. The thickness of the sear control device installed over the sear stop pin affects sear engagement. The method for sear engagement adjustment is applied by changing between sear control devices of different thickness until a desired level of sear engagement is achieved.

A hybrid molded assembly includes a trigger comprising a trigger skeleton and a trigger molded portion that at least partially encompasses the trigger skeleton, a hammer comprising a hammer skeleton and a hammer molded portion that at least partially encompasses the hammer skeleton, and a disconnector comprising a disconnector skeleton and a disconnector molded portion that at least partially encompasses the disconnector skeleton.

A fire control group system for a firearm includes a trigger that includes a trigger base, a trigger extension extending from the trigger base, and an over-travel member coupled to the trigger base at a front end thereof. The trigger base has a sear hook extending therefrom and defining a recess and a transverse bore intersecting the recess. The over-travel member has a contact surface and is moveable relative to the trigger base such that a distance in a vertical direction between the contact surface and the trigger base is adjustable.

A firing mechanism provides a secondary interface between a hammer and a sear of a firearm that will automatically be engaged in case a primary interface between the hammer and the sear fails. In various embodiments, an actuator is employed to facilitate engagement of the primary and secondary interfaces.

A trigger assembly group for use in firearms is disclosed. The trigger assembly group comprises a primary trigger connected to a secondary trigger that is arranged and configured to reduce the incidence of accidental discharge caused by inadvertently rearwardly actuating a primary trigger. The disclosed primary trigger and secondary trigger are arranged and configured for linear movement within a housing. The secondary trigger includes locking wing members that move from engagement with upper locking housing grooves to lower housing grooves. The disclosed trigger assembly group further includes a trigger shoe connected to the primary trigger, wherein the trigger shoe comprises a channel formed therein. A lower portion of the secondary trigger is configured to move from a forwardmost position, extending outwardly from the front face of the trigger shoe, to a rearmost position in which the lower portion of the secondary trigger recedes into the channel of the trigger shoe.

A dart pistol utilizes an assembly of a pistol body, a launch channel, a carriage, a mainspring, an operating bar, an engagement feature, a trigger member, and a retainer pin to adapt a conventional game of throwing darts into a shooting sport. The launch channel is formed into the pistol body such that the carriage, mainspring, and operating bar are slidably mounted between a fore body end and a rear body end. The mainspring is connected between the carriage and the fore body end to impart a launching force to at least one projectile via the carriage. The retainer pin is laterally mounted into the channel to capture the engagement feature of the operating bar until dislodged by the trigger member. The trigger member is pivotably mounted to the pistol body, operatively coupling the trigger member to the operating bar to fire the dart pistol.

A trigger mechanism including a top sear for engaging a cocking piece, a transfer arm for engaging the top sear, and a safety lever and second stage sear which engages the transfer arm. The safety lever prevents unintentional firing of a firearm with the trigger mechanism. A bottom sear cooperates with the safety lever and the second stage sear. A reset spring biases the transfer arm. A single stage operation involves both a first stage spring and second stage spring upon trigger load application. In a two-stage operation, the first stage spring is engaged and then the second stage spring is also engaged. A selector pin provides flexibility to alter the mode of operation of the trigger mechanism between single stage trigger operation and a double stage trigger operation.
