The disclosed firing assembly for use in a firearm according to various aspects of the present technology may comprise a hammer configured to pivot between a cocked position and a firing position. The firing assembly may also comprise a hammer release assembly configured to releasably retain the hammer rearwardly in the cocked position. The hammer release assembly may comprise a housing axially connected to the firearm and a spring-loaded disconnector. In addition, the firing assembly may comprise a biasing component configured to bias the hammer and housing forwardly and upwardly, respectively. The firing assembly may further comprise a trigger assembly connected to the hammer release assembly via a trigger bar and configured to controllably operate the hammer release assembly.

Firearm control mechanisms have a frame, a trigger element connected to the frame and movable with respect to the frame, a selector connected to the frame and pivotable with respect to the frame about a pivot axis, the selector including a first cam surface operably engaged to a follower portion of the trigger element, the selector having a detent portion having a detent surface opposing a spring biased detent follower connected to the frame and operable to reciprocate against the detent surface, the detent surface having a plurality of stable positions, each corresponding to an operating condition of the fire control mechanism, and the detent portion being a body lacking any concave surfaces. The detent surface may have a plurality of flat cam surfaces. At least two of the flat cam surfaces may be perpendicular to each other. A corner may join the plurality of flat cam surfaces.

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.
