  • Publication number: 20230304770
    Abstract: The present disclosure describes a foldable firearm that collapses into a folded state under spring pressure. The foldable firearm may include a foldable grip assembly. The foldable grip assembly may include a foldable pistol grip, a foldable trigger assembly, a folding bar, and a foldable hand stop. The foldable grip assembly may fold into the top shell of the foldable firearm. The foldable firearm may also include an ambidextrous charging handle assembly that may include a bottom portion, a top portion, a guide bar, and two opposing charging handles. The charging handles may be pulled to unfold the foldable firearm, and/or butterflied such that pivoting one charging handle causes the other charging handle to pivot. The first-pivoted charging handle may then be pulled rearwards to unfold the firearm. The first-pivoted charging handle may then be pulled further rearwards to rack the slide of the foldable firearm.

  • Patent number: 11098968
    Abstract: This disclosure describes systems, methods, and apparatus for a follower assembly comprising one or more dummy cartridges, the first thereof comprising an angled follower platform that when pressed between the follower spring and a final live cartridge in the magazine, rotates to a first side of the magazine and enhances follower interaction with a slide lock mechanism. The follower platform may also be angled back to front to further enhance this interaction. The follower platform may include a protruding heel extending laterally from a front portion of the first side of the follower platform configured to interface with the slide lock mechanism. A rear stop may extend from a rear portion of the first side and interface with a downward-facing surface of the magazine near the feed end, wherein contact between these two surfaces causes a front end of the first dummy cartridge to rotate upward.
