Improved firearms including one or more of a removable and/or interchangeable top cover, an improved extractor mechanism, a striker safety mechanism with a direct trigger interface, a sear with direct striker interface, and/or a striker with integral striker spring retention features.

The present specification discloses a sight mount used to attach or otherwise secure an optical sight to a firearm as well as methods of modifying a firearm to receive a sight mount disclosed herein.

A holster system for receiving and releasably retaining a handgun with or without a reflex sight mounted thereon. The holster body comprises a pair of opposing side wall portions and an upper wall portion. The holster body may define a rear accessory sight opening for receiving the handgun with the reflex sight attached thereto. The holster system may include a first rear sight cover selectively and robustly coupleable to the holster body so as to cover the rear accessory sight opening when a handgun with conventional sights extending upwardly about 3/8 of an inch or less mounted thereto is used in conjunction with the holster system. The holster system may also include a second rear sight cover selectively coupleable to the holster body so as to cover the sight opening when a handgun with a reflex sight mounted thereto is used in conjunction with the holster system.

Certain aspects of a novel weapon sight system combine a direct view, a visible light video view, and an infrared (IR) video view mode. Each of the view modes may be viewed individually or simultaneously with one or more of the other view modes through a single viewing aperture. Further, the one or more view-modes may be provided while providing a bore-sighted reticle superimposed on the selected view. Further, the reticle may be powered separately from the video view electronics enabling use of the reticle regardless of the power status video view electronics.

Folding firearms have a frame having a trigger assembly and defining a passage containing a bolt, a barrel assembly pivotally connected to the frame, the barrel assembly including a barrel element defining a barrel axis, the barrel element including a barrel, a plurality of suppressor baffles forward of the barrel, and having an interior space, the barrel assembly including a sleeve encompassing the barrel, the sleeve having an interior defining an expansion chamber in gas communication with the interior space of the barrel element, a front closure and a rear closure at respective ends of the sleeve to provide a gas seal enclosing the expansion chamber, and the sleeve being rotatable about the barrel axis. The sleeve may be movable between an operating condition in which the sight facility is in a first position and a stowage condition in which the sight facility is rotationally offset from the first position.
