An apparatus for ambidextrous control of a bolt carrier and/or a magazine release is disclosed. In certain examples, the apparatus includes a lower receiver of a firearm including a protrusion extending outward from a first side of the lower receiver, the protrusion. The protrusion, in certain examples, includes a first slot for receiving an L-shaped lever, the L-shaped lever having a vertical arm coupled to a bolt catch lever and a horizontal arm that extends through a trigger area to a second side of the lower receiver that is opposite the first side. In certain examples, the protrusion also includes a second slot for receiving a magazine catch lever.

Pistols have a frame, a firing facility operable to discharge the pistol, a safety device connected to the frame and having a safe condition in which discharge is disabled and an operable condition in which discharge is enabled, an actuator responsive to the presence of a safety-indicating element and operative to control the condition of the safety device such that the safety device is in the safe condition when the safety-indicating element is absent and in the operable condition when the safety-indicating element is present, a selector connected to the frame and operably connected to the safety device, and the selector being movable between an enabled position in which the safety device is operably responsive to the presence and absence of the safety-indicating element, and a disabled position in which the safety device remains in the operable condition irrespective of the presence and absence of the safety-indicating element.

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 takedown lever assembly for a semiautomatic handgun includes a receiver, a slide displaceable along a top of the receiver, a grip portion defining a magazine well, and a fire control group that includes a trigger pivotable between a resting position and a pulled trigger position. The takedown lever assembly includes a takedown actuation lever operable between a firing position and a takedown position. In the takedown position the takedown actuation lever permits removal of the slide from the frame. A safety block is operatively coupled to the takedown actuation lever, wherein moving the takedown actuation lever from the firing position to the takedown position moves the safety block rearward, thereby blocking the trigger from rotating to the pulled trigger position. In some embodiments, the takedown lever rotates counterclockwise from the firing position to the takedown position as viewed looking at a left side of the handgun.

A magazine identifier is provided. The magazine identifier is an endless band having a front surface, a rear surface, a first side surface, a second side surface, an inner surface, an upper rim and a lower rim. The endless band is formed of a material with rubber elasticity. For example, the endless band may be made of natural rubber, synthetic rubber, silicone or any material with a similar elasticity to rubber. The endless band is placed over a magazine of a firearm to identify the type of ammunition carried within the magazine and the owner of the magazine.

Provided is a firearm cartridge chamber with a relief feature that traps a portion of a cartridge case within the cartridge chamber when fired. The relief feature causes the cartridge case to deform within the chamber, wherein it optionally separates into a forward section and a rearward section. The deformed case remains trapped after firing, preventing extraction of the fired case and the chambering or firing of any subsequent cartridges, thereby causing a firearm malfunction. The cartridge chamber can distinguish between higher and lower pressure cartridges by allowing for normal firing and function with blank training ammunition while also facilitating localized deformation of the cartridge case when firing standard ammunition that includes one or more projectiles. The inventive chamber prevents more than one higher pressure round from firing while allowing lower pressure or training rounds to fire without limitation, which aids in enhanced safety during training exercises.
