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.

A toy launcher with a drum magazine assembly that has a rotatable drum portion mounted for rotation, with a rear plate and a central support with an opening for a support axle. A ring of projectile holders is connected to the rear plate, with each projectile holder holding at least two projectiles arranged in a generally radially stacked configuration. Generally radially extending walls are located between adjacent projectile holders. Each of the projectile holders includes a slot on a radially inner side into which a projectile biasing arm extends at a projectile launch position. A pusher is located in the housing adjacent to the projectile launch position. Drive wheels are positioned in front of the drum magazine assembly at the projectile launch position. The drive wheels are motorized so that they rotate to propel a projectile pushed from the drum between the drive wheels for launching the projectile.

A number of embodiments of a firearm are disclosed where the firearm includes a magazine configured to hold the bolt in an open position when the magazine is empty. In one embodiment, the firearm includes a bolt stop mechanism that moves between a first position where it allows the bolt to cycle between an open position and a closed position and a second position where it holds the bolt in the open position. The magazine is configured to actuate the bolt stop mechanism to the first position when the magazine is empty.

A firearm is provided comprising a frame which defines a forward aperture. A cylinder is mounted rotatably to the frame to rotate on a cylinder axis. The cylinder defines a plurality of passages each at a common radius from the axis, each passage includes a chamber and a rifled bore. At least one of the passages is being chambered for a different caliber than at least one other of the passages.

A structure of a wheel-type positioning device includes a gun body, a wheel and a grip portion. A bullet is placed into a receiving slot of the wheel through a lead trajectory on the gun body. The receiving slots of the wheel can sequentially correspond to a barrel to complete loading actions through frontward and rearward reciprocating displacement actions of the grip portion, and through a linking rod of the grip portion driving a limiter thereon to rotate the wheel.

Drum magazines have a housing defining an ammunition passage having an outlet, a first spring mechanism adapted to bias ammunition in the passage toward the outlet, and a follower element in the passage, the follower element including a second spring mechanism adapted to generate a biasing force against a passage surface portion, such that the follower resists movement within the passage in the absence of a deliberately applied force. The magazine may be a drum magazine, and the passage may have a spiral shape. The first spring mechanism may include a control adapted to selectably change the first spring mechanism from a biasing condition in which force is applied to the follower element for motivating ammunition toward the outlet, and a loading condition in which the first spring mechanism is restrained to facilitate loading of the magazine in the absence of a biasing force.
