摘要： A charging handle accessory has an upper portion with a pair of parallel, spaced-apart sidewalls connected at their upper extent. The upper portion is configured to be assembled over an upper portion of the charging slide. A lower portion has a pair of parallel, spaced-apart sidewalls connected at one end. Each of the sidewalls of the lower portion has a lip configured to engage a lower extent of the charging slide. A sliding connection is provided at the lower extent of the upper portion and the upper extent of the lower portion, wherein the upper and lower portions are coupled together in sliding relation. A fastener extends between the upper and lower portions to secure the upper and lower portions against sliding relative to one another and secure them on the charging slide of the firearm.

摘要： An assembly for a modular, compact firearm includes a universal action and an interchangeable, non-reciprocating barrel. The barrel may directly mount various optical sighting systems and provide integral muzzle compensation and sound suppression capabilities. The firearm utilizes a universal action comprised of a slide assembly, breechblock assembly, recoil assembly, and receiver which mounts a variety of barrel assemblies and assembles into a variety of different grip frames. The action of the firearm utilizes a partially-locked breechblock which amplifies the inertia of a slide.

摘要： The invention relates to a firearm, comprising: a housing (1) having a barrel (2) arranged therein; a magazine, which can be inserted into a receptacle of the housing and which has cartridges; a breechblock (3), which can be moved relative to the housing (1) in the longitudinal direction of the barrel (2), for conveying cartridges out of the magazine into a cartridge chamber (4) located in the housing, and for conveying cartridge cases (5) from the cartridge chamber (4) to an ejection port (6) after a shot has been fired. An extractor (8), which is connected to the breechblock (3) and is preloaded in the direction of the cartridge case (5) by means of a spring (7), and an ejector (9), which is likewise connected to the breechblock (3), are provided for the ejection of the cartridge cases (5). The ejector (9) is arranged in a cylindrical ejector seat (10). The extractor (8) is arranged on an extractor seat (11), which is arranged for pivoting about the ejector seat (10). The extractor seat (11) can be fastened at different positions along the pivoting path in order to adjust the ejection direction of the cartridge cases (5).

摘要： A semiautomatic pistol has a takedown lever which also acts as an ejector. The takedown lever includes an ejector head and a finger. The finger is engageable with a sear when the takedown lever is rotated by depressing the ejector head through the ejection port when the slide is out of battery. This rotates the sear so that the slide may be removed by sliding it toward the muzzle end of the pistol.

摘要： The inventive disclosures pertain to an improved handgun (and related retrofit/after-market kits) that incorporates an improved gunsight and ergonomically enhanced pistol-grip member. In embodiments, an elongated gunsight-augmentation member is adapted to be inserted between a handgun's existing rear and front gunsights such that the gunsight has been basically transformed into a barrel-length U-shaped channel that makes it clear to a user how to line-up a target, while ensuring that the entire length of the device has a smooth shape and edges to significantly reduce snagging when drawing the firearm. The gunsight-augmentation member can also incorporate an internal fiber-optic rod as a visual aid to line-up a firearm. In variations, the improved handgun incorporates an ergonomically enhanced finger-receiving member disposed at the bottom surface of the pistol-grip and/or magazine that is especially useful for compact handgun designs.

摘要： A trigger bar for a semi-automatic firearm including a continuous U-shaped body and a single tab extending outward from a base of the U-shaped body. The tab is offset from a centerline located between legs of the U-shaped body. The trigger bar is configured to operate the sear when the legs are coupled to a sear assembly of the firearm, and only the single tab is coupled to a trigger of the firearm via a trigger bar slot of the trigger.

摘要： A high capacity handgun/pistol is disclosed with a horizontally oriented magazine that is aligned with and disposed beneath the gun barrel. The magazine defines a plurality of hollow tubes arranged radially around a central axis about which the magazine can rotate automatically during operation of the handgun/pistol. The hollow tubes each contain a plurality of ammunition rounds, and can each be aligned with a loading tray one at a time, wherein a coil spring will push out a single round at a time onto the loading tray. The handgun uses a gun slide to load a new round into the chamber via the loading tray, and further enabling the loading tray to automatically rotate the magazine as each hollow tube becomes empty. Moreover, the slide will re-set a hammer to re-engage with a sear, after a pulled trigger releases the hammer to strike a firing pin. The handgun is further equipped with a selector switch enabling automatic and semi-automatic firing modes, wherein the semi-automatic firing mode can be further specified to select a three round burst fire mode. The handgun can also be configured with a simpler firing mode cam and fewer parts that limits it to semi-automatic firing mode. Additionally, the handgun barrel is separable and replaceable if the barrel becomes too hot after rapid fire.
