Abstract: Systems for a firearm are provided to increase safety, reduce complexity, and improve precision of the weapon. In general, examples of the systems including a safe axis firing pin that prevents unintended discharge are described herein, where the firing pin is not aligned with the primer of a chambered cartridge until the user intends to fire the firearm. Embodiments of the system are capable of modular installation and generally include a user-actuated trigger configured to displace the firing pin from a safe axis to a firing axis, by rotation, translation, or a combination thereof. Additional features are provided to prevent displacement of the firing pin by input other than the trigger, e.g., if the firearm is dropped. In another aspect, examples of the systems described herein include a barrel interfacing a slide where the barrel and slide include features to centrally align the barrel as the slide completes a cycle.

Abstract: A handgun forearm support suitable, for example, for target and competitive handgun shooting, includes a grip adaptor configured to engage the grip of a handgun, an intermediate joint member that attaches to a proximal end of the grip adaptor with a pivot assembly, and a forearm brace that rotatably and lockably engages a proximal end of the intermediate joint member. Preferably the locking engagement is hand-operable, for example a joint having mating parts with interlocking radial teeth, with a wing nut and bolt engagement. The grip adaptor may insert into a recess in the handgun grip, or engage the sides of the handgun grip. One or more removably locking pins or screws lock the handgun to the grip adaptor.

Abstract translation: 例如，用于目标和竞争性手枪拍摄的手枪前臂支撑件包括构造成接合手枪的手柄的抓握适配器，用枢轴组件附接到握持适配器的近端的中间关节构件，以及 前臂支架，其可旋转地且可锁定地接合中间关节构件的近端。 优选地，锁定接合是可手动操作的，例如具有互锁径向齿的配合部件的接头，具有翼形螺母和螺栓接合。 握把适配器可以插入手枪把手中的凹部中，或者接合手枪把手的侧面。 一个或多个可拆卸地锁定的销钉或螺钉将手枪锁定到握持适配器。
