Representative implementations of devices and techniques provide a handgun lower receiver to be used with firing components from a donor handgun. The lower receiver includes additional features to improve stability during a triggering event. The additional features can include a rear attachment port comprising a receptacle with a cavity for receiving a brace extension component. The receptacle can have one or more coupling features for coupling the brace extension component to the rear attachment port.

Apparatus and associated methods relate to a handgun brace arranged with a rigid structure extending radially away from a handgun trigger guard, and having a forward-facing surface configured to physically engage with at least one finger of a user's non-primary grip hand in a stable position below the handgun's barrel and in front of the handgun's trigger, such that a counter-force applied by the finger(s) at the forward-facing surface tends to prevent the handgun (especially the muzzle), from rising or rotating in response to shooting, such as due to muzzle jump. In an illustrative example, the brace may be releasably fixed to the handgun (e.g., as a modular handgun accessory). A handgun brace that substantially mitigates the unwanted effects of muzzle jump/recoil may advantageously yield higher shooting accuracy and beneficially promote proper handgun grip positioning.

A pistol brace includes a main frame, a forward hand grip, an adjustable front bracket attaching the main frame to the forward hand grip, a pistol muzzle guard extending forwardly at a top of the hand grip, a stock frame member attached to a rear of the main frame by an adjustable stock bracket having a stock pivot hinge for collapsing and extending the stock frame member. A stock adjustment slide allows for adjustment of the length of the stock to accommodate different size operators. A collapsible butt stock is pivotally fitted to an end of the stock frame member. A rail mount above the forward hand grip attaches to a picatinny rail on an underside of the pistol barrel and a pistol grip mounting mechanism and a pistol locking mechanism secure the grip of the pistol to the main frame.

In some embodiments, a grip for a shooting device comprises a first body portion configured for attachment to the shooting device and a second body portion engaged with the first body portion. The second body portion is moveable with respect to the first body portion between first and second positions. A biasing member is arranged to bias the second body portion to the first position. In some embodiments, the second body portion comprises a guard defining a guard cavity and at least a portion of the first body portion is oriented in the guard cavity.

A method includes defining a designation point on a target within a view area of a scope coupled to a firearm and determining an angular motion deviation of a muzzle of the firearm from the designation point. The method further includes initiating firing of the firearm when the angular motion deviation is below an acceptable level.

A self-stabilizing small arm having a barrel assembly rigidly connected to a stock assembly. The small arm includes at least one shooter interface surface and a stabilization assembly controlling the relative position of the shooter interface surface and the barrel assembly or stock assembly. The stabilization assembly includes (i) at least one movement sensor; (ii) at least one actuator; and (iii) a controller using signals from the movement sensor to operate the actuator in order to compensate for unintended movement of the small arm.
