A safety guard for an ammunition cartridge (cartridge) of a conductive energy weapon (CEW) includes a body having a first electrical contact on a first side of the body and a second electrical contact on a second side of the body opposite the first side of the body. The first and second electrical contacts are in electrical communication with each other through the body. The first and second electrical contacts are configured to contact a first electrode of the cartridge and a second electrode of the cartridge, respectively, when the body is placed over the cartridge. The safety guard is configured to prevent the cartridge from firing when a firing input, such as a trigger pull, is received by the CEW from a user. In implementations the body includes at least one clip having a projection configured to be inserted in a corresponding depression of the cartridge of the CEW.

A removable firearm chamber-obstruction mechanism includes a locking mechanism including at portion configured to be inserted in a chamber of a firearm and engage the chamber so as to be locked in place. The locking mechanism includes one or more finger actuators, a thumb bar actuator engaged with the one or more finger actuators, a release key connected to the thumb bar actuator, and a tooth key disposed in abutment against the release key. A handle covers the locking mechanism, and a lid encloses the handle. The locking mechanism locks and unlocks the tooth key upon a successful manual actuation of the one or more finger actuators and the thumb bar actuator, such that the tooth key engages the chamber in a locked position and is unengaged from the chamber in an unlocked position.

A handgun safety device comprising a safety element with a firing interrupting element configured for snug projection between a face of a duty cartridge and a fore end of a functional firing element, said safety element being articulated at a first end of a cord having a full length, with a second end configured for attaching to an article worn by a user.

A smart safety contraption for use with a firearm. The smart safety contraption includes of a tubular body adapted to fit into a barrel of the firearm. The tubular body having a front end having a first diameter and a back end having a second diameter. The first diameter is smaller than the second diameter. At least part of the front end is positioned within the barrel directed to a muzzle of the firearm. The smart safety contraption further comprises an image capturing device installed within the front end and directed to objects located in front of the barrel. The smart safety contraption further includes a control unit adapted to cause an image to be captured by the image capturing device upon receiving an indication corresponding to, e.g. a motion of the trigger. The image may include a graphic element designed to indicate a virtual point of impact.

The Gun Disabling Mock Ammunition is a device made to the same outward dimensional specifications and aesthetic characteristic as actual firearm ammunition; however, when attempted to be fired from a firearm, the effect is a non-hazardous, exothermic reaction taking place within the ammunition cartridge, producing heat substantial enough to bond the Gun Disabling Mock Ammunition to the inside of the chamber of the firearm, rendering the firearm immediately disabled and the chamber destroyed. This is accomplished while posing no risk of injury to the user or bystanders. The components of the Gun Disabling Mock Ammunition are non-toxic, non-hazardous, and chemically stable. Through use of the Gun Disabling Mock Ammunition, a reduction of deaths, injuries and crimes resulting from the intentional and unintentional use and access of unsecured legal, illegal and insurgent-force firearms can be achieved.

An external lock apparatus for a gun includes a gun receptacle. The gun receptacle is configured to receive a portion of the gun. An external lock is configured to engage with the portion of the gun when the gun is inserted into the gun receptacle. The external lock has on OPEN position and a LOCKED position. The external lock further includes an interference member. The interference member is configured to engage with the gun such that the gun cannot be removed from the gun receptacle and the gun cannot fire when the portion of the gun is received within the gun receptacle and the external lock is in the LOCKED position. In the alternative, the gun cannot be fired but can be removed from the gun receptacle if the portion of the gun is received within the gun receptacle and external lock is in the OPEN position.
