Provided is a pistol striker safety plunger having an axially nonrotatable plunger body configured for installation in a pistol slide to selectively block forward movement of a striker when in a fist position and to allow forward movement when in a lifted position. The body includes a bottom surface configured to interface with a lifting trigger bar and having a beveled forward portion being substantially flat rearward thereof. Alternatively, an adaptable pistol slide kit may be interchangeably operable on pistol frame assemblies of different configurations. The kit includes a slide body with a striker safety plunger socket and a plurality of interchangeable axially nonrotatable striker safety plungers configured to be slidably received in the plunger socket. A first plunger has a bottom surface with beveled forward and rear portions and a second plunger has a bottom surface with a beveled forward portion and substantially flat rearward of the forward bevel.

A firearm operating system includes a housing, a central pivoting member disposed within the housing, a trigger including a portion disposed within the housing and a portion extending outside the housing such that the portion of the trigger within the housing includes a hole and at least one finger that extends in a first direction from the hole. Due to movement of the trigger, the at least one finger presses against the central pivoting member to cause the central pivoting member to rotate.

Trigger-cycled firearms have a frame, a barrel, a bolt assembly connected to the frame in registration with the barrel and operable to reciprocate between a retracted position and a forward battery position, a trigger lever connected to the frame and operable to move between a forward rest position and a rearward actuated position, and the trigger lever operably connected to the bolt to move the bolt from the forward battery position to the retracted position and to release the bolt to the forward battery position and discharge the firearm in response to movement of the trigger lever from the forward rest position to the rearward actuated position when the bolt is in the forward position. There may be a connector bar pivotally connected to the frame and operably engaged to the bolt assembly and to the trigger lever. The connector bar may be slidably connected to the bolt assembly.

Trigger assemblies are provided for restraining a firing pin of a firearm on a selective basis. The triggers assemblies include a first and a second lever mounted for rotation within a housing. The first lever is configured to be rotated by the user, and rotation of the first lever imparts rotation to the second lever to initiate the discharge of the firearm. The trigger assemblies also include a safety mechanism having a safety lever that is movable between a first and a second angular position. The safety lever is configured to prevent movement of the first and second levers when the safety lever is in its first angular position, thereby preventing discharge of the firearm.

An intrinsically safe firearm may include a handle and a frame connected by a pivot pin. One or more latches of the firearm can temporarily fix the firearm in a stowed orientation or a deployed orientation. In the deployed orientation, a magazine of the firearm can be removed from the handle; a slide of the firearm can be removed from the frame; a magazine safety allows a firing pin to strike a primer of a round in the firearm; and a trigger of the firearm is accessible to discharge the round in the firearm. In the stowed orientation, the magazine is not removable from the handle; the slide is not removable from the frame; the magazine safety prevents the firing pin from striking the primer; and the trigger of the firearm is not accessible.
