Apparatus and methods facilitating the discharge of a firearm by sound are disclosed. The present invention relates to methods and means of firing a firearm on the firearms receipt of a sound avoiding the use of a mechanical trigger facilitating the grip of the firearm not changing during the act of firing avoiding any motion by the shooter therefore improving the accuracy of the aim of the firearm. No personalization or additional security is incorporated in the firearm.

A trigger mechanism for semiautomatic and automatic firearms may include a trigger body having a trigger which extends rearwardly toward the back of a pistol grip so that a user may fire the weapon by pressing downwardly on the trigger with the user's thumb.

The current invention discloses a semi-automatic firearm which has two sections which can move independently of each other in opposite directions, in line with the barrel. One section contains the barrel and a trigger that can be pushed forward to activate the gun. The second section contains a trigger activator such as a rod, edge, or object or it positions or supports a body part as the activator such as a finger or thumb and may contain a hand grip or shoulder stock for support and/or leverage. A shooter holds the firearm up using up to two hands and optionally shouldering it for support and aims to shoot. Once the activator object or body part pushes into the push activated trigger, it activates the next step in the firing sequence of the self-loading firearm such as the release of a hammer, striker, or other object or impulse that ultimately causes the cartridge or round in the gun to be fired. Once fired, the self-loading gun cycles, typically ejecting the used case, and resetting the internal mechanisms.

This device is designed to universally attach to firearms for both left, right, and dual handed use. It assists users of firearms who may or may not have a deformity of their hands from damage sustained by birth or environmental accident, resulting in limited use of Phalanges and Metacarpals. User input activates the device with the closing an electronic circuit from the battery to the circuit board, commanding the Linear Actuator to move. The Linear Actuator is connected to the Trigger Actuator resting in the vicinity of the trigger. The Trigger Actuator starts one cycle by making contact with the trigger, depressing it, causing the firearm to discharge as designed when the trigger is pressed. After the actuator travels a distance in one direction, it is withdrawn, releasing pressure on the trigger, resetting the trigger and ends the cycle. It is now ready to complete another cycle upon user input.

A form-factor for a palm pistol which reduces recoil movement and engages natural point of aim has a body for receiving and containing pistol action, a finger grip disposed on a top side of the body, a thumb grip disposed on a bottom side of the body, and a metacarpals grip disposed on a back of the body such that a bore axis of a barrel in the pistol action forms an angle with the metacarpals grip between 0 and 90. This form-factor provides palm-forward, knuckles-up grip that aligns the barrel with the operator's forearm bones, thus distributing the rearward recoil force directly in-line with the forearm bones, thereby reducing recoil movement, and utilizing natural point of aim of the user.

A firearm spade grip assembly can comprise a firearm, paddle trigger assembly, and/or a mounting system. A paddle trigger assembly can comprise a base spanning between and comprising a base forward end and a base aft end; a paddle trigger coupled to the base; a trigger actuator coupled to the base; and/or an actuator housing coupled to and extending forward from the base, wherein the trigger actuator is disposed at least partially within the actuator housing. Movement of the paddle trigger can be configured to translate the trigger actuator. A mounting system of a firearm spade grip assembly can comprise a mounting base configured to couple to a firearm receiver base or a firearm receiver of the firearm.
