Abstract: A gun has parts that slide past one another during operation. A coating is formed on at least a surface of a first part that contacts a second part. At least an upper layer of the coating is porous and comprises a thermoset polymer and a filler. One or both parts may be part of a gas-operated reloading mechanism. The coating prevents jamming by excluding particles, yielding to particles that still manage to intrude, and by providing a reservoir for lubricant. The coating reduces clearances, improves accuracy, and reduces operating temperatures. The coating excludes particles from the lubricant, effectively allowing a large volume of lubricant to be used without the drawback of trapping dirt and other contaminants in the lubricant.

Abstract: 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).

Abstract: A trigger assembly has a sear with a stop surface engageable with a reciprocating component for holding the reciprocating component in a cocked configuration. A trigger is movable into and out of engagement with the sear to hold and release the reciprocating component. A drop pendulum has a trigger cam engageable with the trigger. A spring acts between the trigger and the drop pendulum to bias the trigger cam into engagement with the trigger. The drop pendulum also has a head cam follower engageable with the reciprocating component. Motion of the reciprocating component acting through the head cam follower and the trigger cam forces the trigger to return to a configuration of engagement between the trigger and the sear. Use of the drop pendulum improves the stability of trigger mechanisms and effectively inhibits accidental discharge of firearms when subjected to inertial forces which occur when the firearm is dropped.

Abstract: This application is directed to a firearm that is functional, but is not fully functional as it is incapable of discharging ammunition, e.g., causing ammunition to ignite and discharge a bullet. Related methods, techniques, and approaches are also discussed. In embodiments, the firearm is functional, but not fully functional and it is impractical and/or irreversible to alter the firearm to make it fully functional through replacement of interchangeable parts that correspond to that particular firearm model. In embodiments, the firearm is also identifiable as being less than fully functional, e.g., it is incapable of discharging ammunition.
