Provided are trigger safety devices for a gun configured to conveniently lock/unlock the trigger. Generally, the trigger safety device comprises a first component, a second component, means for releasably limiting the positions of the second component and an alarm module. The first component is attached to the barrel portion of a gun. The second component is either hingedly attached to the first component or slidably attached to the outer surface of the first component. The alarm module is disposed in the first component and is configured to alert a user when the trigger safety device is unlocked. In general, the alarm module comprises one or more sensors, a power supply, an alarm notice generator and a control system in electrical communication with the sensors, power supply and the alarm notice generator.

A bolt action firearm that cocks the firing pin upon closing the bolt and includes a cam pin with dual heads for a high velocity rimfire cartridge. In one embodiment, actuating the main spring while closing the bolt, instead of while opening the bolt, more uniformly distributes the physical energy required by the user over the bolt actuation cycle. The dual heads of the cam pin provide symmetric reactive forces with dual cam slots, thereby preventing the cam pin from skewing or canting within the cam slots. A safety system is provided for the trigger mechanism and a robust connecting systems for the stock.

Handguns are disclosed including improved safety mechanisms, improved magazine catch mechanisms, improved slide stop mechanisms, and improved optics mounts. Selected embodiments may include one or more than one of such improvements. Embodiments may be particularly suited to semi-automatic handguns, including 1911-style handguns and/or 2011-style handguns. Other embodiments may also be implemented in the context of different types of handguns.
