A firearm including a barrel bushing is disclosed. The barrel bushing provides for guidance of the slide without a need for forward rails. The barrel bushing is retained by a bushing stop that allows the slide to be removed while the recoil spring and bushing are retained on the barrel.

Various embodiments for an angled action firearm that counteracts muzzle rise are described. The angled action firearm includes a receiver having a first receiver end and a second receiver end. The receiver has a top surface sloping upwards from the first receiver end to the second receiver end. The angled action firearm further includes a slide moveably coupled to the receiver having a bottom surface opposite that of the top surface of the receiver. The slide has a first slide end and a second slide end, where the angled bottom surface of the slide slopes upward from the first slide end to the second slide end. The angled action of the slide causes downward pressure during recoil counteracting muzzle rise.

A magazine is provided for a firearm. The magazine comprises a locking mechanism. The locking mechanism has a user interface adapted to enable a user to select between a locked condition and an unlocked condition. The locking mechanism has a rotor movable between a first rotational position when the locking mechanism is in the locked condition and a second rotational position when the locking mechanism is in the unlocked condition. The magazine comprises an elongated shaft connected to the rotor. The magazine comprises a block element connected to the elongated shaft. The block element is adapted to move between a first position when the locking mechanism is in the locked condition in which at least one of firearm operation and magazine extraction are prevented, and a second position when the locking mechanism is in the unlocked condition in which firearm operation and magazine extraction are enabled.

A barrel assembly for use in a semiautomatic firearm, including a barrel and a takedown lever. A rear portion of the barrel includes a follower lug and a rear lug extending from an underside of the rear portion. The follower lug further includes a follower notch. A pin of the takedown lever includes a notch with a vertical face configured to contact a vertical face of the follower notch when the firearm is in the locked position. The rear lug is configured to be supported by a portion of a locking block of the firearm prior to firing and during a portion of the recoil period. The modifications to the barrel assembly result in increased dwell time and accuracy of the firearm.

The present invention relates to a gun (1) with a pair of barrels (6, 6) flanking each other, each delimiting a cartridge chamber (12, 12). The gun further comprises a pair of firing pin tips (8, 8) for a cartridge (10, 10), movable towards the cartridge chambers (12, 12) by means of a firing device operated by a trigger (4, 4); such device acts on the firing pin tips to allow a substantially simultaneous advancement thereof. The invention also relates to a two row magazine for a double barrelled gun.

Improvements to firearms that load cartridges from a magazine and/or a clip are disclosed. Specifically, improvements to slide assemblies and bolt assemblies to depress a cartridge in a magazine and/or a clip are provided. Such improvements include a sloped bottom-facing surface of the slide assembly and/or bolt assembly. The sloped bottom-facing surface is sloped along the length of the portion that contacts a cartridge in the magazine and/or clip when the slide assembly and/or bolt assembly reciprocates.

A firearm assembly including a receiver, a barrel, a locking block and a slide configured to provide rapid changing of a barrel of a handgun wherein the barrel may be for an alternate caliber round of ammunition. The locking block is configured to be secured within the receiver and includes an upper surface that has front rise member, a rear rise member and a valley intermediate thereto. The upper surface of the locking block is mateably shaped with the second portion of the barrel, in particular the lower portion thereof. The lower portion includes a front shoulder member, a rear shoulder member and a notch formed therebetween wherein the notch is configured to mateably engage the rear rise member of the locking block. The slide of the present invention includes a void intermediate the sidewall and the extractor housing. A shim is provided to be secured within the void.
