A sensor system for a firearm is disclosed. The sensor system contains a body, a mounting facility adapted to mount the body to the firearm, a first accelerometer connected to the body operable to generate a first acceleration signal based on detected acceleration of the body, a second accelerometer connected to the body operable to generate a second acceleration signal based on detected acceleration of the body, the first accelerometer operable for detection of accelerations within a first range between a first lower limit and a first upper limit, the second accelerometer operable for detection of accelerations within a second range between a second lower limit and a second upper limit, the first lower limit being less than the second lower limit, and the first upper limit being less than the second upper limit, such that at least portions of the first range and the second range do not overlap.

An accessory for a firearm includes a deflector structured to alter a path of discharge gasses and/or debris after such gasses and debris pass a Loaded Chamber Indicator (LCI) of the firearm. The LCI indicates a presence of a cartridge within a firing chamber of the firearm, but openings within and around the LCI also provide a path for hot gasses and debris to strike accessories, which causes fouling and other deterioration.

A firearm (1) includes a detection system (10) suitable to detect a configuration change of the firearm from an initial configuration. The detection system (10) includes a detection device (100), on the slide (20) suitable to be moved, starting from an initial position, to a detection position in which the detection device (100) detects a configuration change of the firearm. An idler device (200) on the slide (20) engages with the detection device (100) which moves the idler device (200). The detection device (200) includes at least one primary sensor element (250), a receiver device (300) on the main body (5) suitable to receive the information of the configuration change of the firearm from the primary sensor element (250) and at least a secondary sensor element (350).

Firearm stock of the type which comprise an electronic control unit in said stock and comprising a receptacle with at least one opening in the stock comb and which is configured to receive a display device. It also comprises a battery configured to be connected to the display device and a control unit configured to receive data from the electronic control unit and send it to the display device. When the display device is installed it is housed in the receptacle and the user has visual access to it by the opening of the comb so that he has access to all the firearm information in his own line of sight when he is aiming. Furthermore, the stock is equally valid for left and right-handed people.
