A training pistol and method of providing the same having fixedly and adjustably removable base extensions to emulate the feel of a corresponding live fire pistol, a trigger mechanism configured to be fit in a compact pistol to provide a large number and sophistication of sear surfaces and biasing members such as helical springs and lasers into a compact pistol to provide training for an end user such as concealed carry holder or law enforcement personnel.

The present disclosure provides systems, devices, and techniques that can be implemented at a gun, such as an electromechanical gun. The gun may include a barrel located within a slide and a cylindrical spring enveloping the barrel. The barrel may be configured to act as a guide rod for the cylindrical spring, and the cylindrical spring may be configured to bias the slide in a forward battery position. The gun may include an electronic component such as an energy store, a processor, or a circuit board, located under the barrel and forward of the trigger when the gun is in an upright position. The gun may include a physical transmission medium that electronically couples the electronic component with an additional electronic component located rearward of the trigger, and the physical transmission medium may be at least partially encapsulated by a trigger guard.

A multi-function dry fire training device to be inserted into the chamber of a firearm, which comprises an illuminator for emitting, upon receiving a command from a controller, a beam of visible or invisible illumination from the barrel of the firearm, the beam being parallel to its central axis; a controller for controlling the functionality of the device including illumination of the illuminator, in response to activation of the firearm trigger; an actuator, being electrically connected to the controller, for activating the controller whenever being struck by the firearm striker and a power source for providing DC power to the controller and illuminator.

A toy gun and a toy gun assembly are provided. The toy gun includes a gun body; a first power supply, a first printed circuit board (PCB), an infrared emitter, a first infrared receiver, a first vibration motor, a trigger, a first display module and a first speaker are arranged in the gun body; the gun body has a gun body portion and a handle portion; the first vibration motor corresponds to the handle portion; and the first display module is exposed from an outer side of the gun body and is disposed towards the upper rear side in a displaying manner.

An apparatus includes a bolt carrier assembly and a bolt assembly. The bolt assembly includes a bolt body member, the bolt body member having a proximal end portion and a distal end portion, and defining a longitudinal axis extending from the proximal end to the distal end. The bolt assembly includes a guide member attached to proximal end portion and the guide member is parallel to the longitudinal axis. The bolt assembly further includes a bolt chamber interface attached to a distal end portion, the bolt chamber interface nests within an interior wall of a firearm chamber, and the bolt chamber interface limits rotational and axial movement of the bolt assembly relative to the firearm chamber. The bolt assembly includes a bolt nipple connector for mating with a nipple assembly of a magazine assembly.

A device can include one or more sensors configured to output sensor data, and a trigger detection module configured to receive the sensor data from the one or more sensors and to determine whether a trigger event has occurred. The trigger detection module can be configured to output a trigger detection signal when the trigger event is detected. The trigger detection signal can be configured to be used by an augmented reality or virtual reality system to cause an augmented reality or virtual reality event.
