A location-based gun magazine has a housing having a plurality of locking apertures, a spring, a wireless receiver switching device, a battery, and an electromagnet locking mechanism. The electromagnet locking mechanism has a locking tab for engaging and locking with the plurality of locking apertures, the locking tab actuatable via the electromagnet, the electromagnet receiving a signal from the wireless receiver switching device. The wireless receiver switching device may have a radio receiver, a GPS chip, or other device for receiving location-based information.

A firearm magazine includes an elongated tube defining a tube axis and having an upper end with feed lips and an opposed lower end. The tube has elongated front, rear, left and right side walls. A closure element is a bottom cap removably connected to the lower end of the tube and includes a latch movable between a retention position wherein the closure element is secured to the tube, and a released position wherein the closure element is removable from the tube. The closure element includes a spring loaded latch biased upward to lock into its retention position, and the closure element is slidably receivable onto the lower end of the tube by movement transverse to the tube axis in a removal direction. The latch is on a tube side opposite from the removal direction and configured to abut the tube to prevent removal when locked in its retention position.

A handgun has a grip portion defining a magazine well, the grip portion having a web region configured to be grasped between a thumb and an index finger, a forward portion of the web region defining a first width. The grip portion also has a palm region configured to be grasped by a user's palm, the palm region defining a second width greater than the first width. A magazine is configured to be received in the magazine well and includes a hollow magazine tube with a single-stack portion and a double-stack portion positioned below the single-stack portion. For example, front portions of the opposite tube sidewalls have a stepped shape between the upper tube end and the double-stack portion.

A device implementable on a firearm includes a magazine funnel and a securing mechanism. The magazine funnel is configured to couple to an opening at a bottom of a grip of the firearm. The magazine funnel has a first side and a second side opposite the first side. The securing mechanism protrudes from the first side of the magazine funnel such that, when a gap related to the securing mechanism is expanded while the magazine funnel is coupled to the opening with the securing mechanism inserted into a void of the grip, the securing mechanism secures the magazine funnel to the grip of the firearm.
