This disclosure describes systems, methods, and apparatus for an ejection port cover allowing tool less insertion and removal. This is accomplished via a fixed pin and a spring-loaded pin that both mate with hinge openings at ends of the ejection port. The spring-loaded pin can be longitudinally biased by a spring, such as a torsion spring. This same spring can perform biasing of the ejection port cover toward an open position as well as biasing of a flag extending from the spring-loaded pin into a locked position when the ejection port cover is not installed.

An adjustable spent cartridge casing deflector includes a deflector body directly attached on the firearm; wherein the deflector body includes a front side having a deflecting surface facing an expected trajectory of spent cartridge casings and being near an ejection port; wherein the deflector body is rotatably arranged on the firearm via an adjustable axis to adjust a direction of the deflecting surface; wherein the adjustable axis is configured to be rotated for selectively tightening or untightening the deflector body mounted on the firearm.

A locking mechanism for a firearm accessory that is meant to be attached to the rail system of a firearm such as a pistol. The locking mechanism features a locking screw that can either be a set screw or a jam socket screw that is advanced within a bore housed by the device until the screw contacts and raises a platform featuring a protrusion configured to engage with a rail system on a firearm frame. The device can also feature a spring located between the locking screw and the platform that can be used to keep tension on the platform. In addition, the device can feature a thumbscrew that is used to advance the locking screw within the device's bore. The locking device is attached to the firearm and screwed into place, but has to be removed through the use of a separate tool.

A firearm shell casing catching system for collecting casings ejected from a firearm includes a mounting assembly, casing deflector, and a hopper.

Firearm ejectors and receivers and firearms including such firearm ejectors are disclosed. An example ejector for a firearm includes a body including a projection extending therefrom, the ejector to be movably coupled to a receiver of the firearm to enable the projection including an engagement surface to be disposed in a movement path of a breechblock, the engagement surface to be engaged by a cartridge casing during a recoil process to enable the cartridge casing to be ejected from the firearm; and a spring to bias the body relative to the receiver, the body to be movably relative to a longitudinal axis of the receiver upon impact with the cartridge.

Improved firearms including one or more of a removable and/or interchangeable top cover, an improved extractor mechanism, a striker safety mechanism with a direct trigger interface, a sear with direct striker interface, and/or a striker with integral striker spring retention features.

A firearm training barrel for a replica gun, the gun having a slide and a magazine with a follower. The barrel includes an extended or extendable member positioned or positionable to simulate the presence of one or more pellets in the magazine, whereby the replica gun can be fired even after the magazine's follower has reached the top of the magazine.
