The present disclosure provides systems and techniques that can be implemented in a gun, such as an electromechanical gun. The gun may charge a capacitor bank, identify a trigger break based on an output generated by a trigger sensor, and transmit a signal based on the trigger break. Transmitting the signal may result in the capacitor bank discharging electric charge such that electric current is directed at an actuator mechanism so as to cause displacement of the actuator mechanism, and the displacement of the actuator mechanism may result in the propulsion of a projectile through a barrel of the gun. The gun may determine that a projectile has been fired based on an output of an accelerometer or a gyroscope, and the gun may recharge the capacitor bank in response to determining that the projectile has been fired.

Live firing a semi-automatic pistol, resets the firing pin, and the semi-automatic pistol is ready to be fired again. With dry fire practice, the shooter removes a hand from the pistol and ratchets the slide resetting the firing pin to simulate each shot. This invention provides a simulated ammunition magazine that provides realistic muscle training by duplicating the trigger action of normal live fire, the feel and the sound of the release of the firing pin, and the resetting of the trigger for additional trigger activations. There is no firing pin interaction, and no alterations required to the pistol. This dry fire training device is narrow enough to work in single stack pistols.

The invention relates to a safety and / or decocking control mechanism that is centrally positioned and partially embedded within the firearm frame. This arrangement allows the bolt assembly to pass over the mechanism when opened. The control mechanism is ergonomically mounted, ensuring accessibility for both left-handed and right-handed users. It facilitates four distinct positions when the bolt assembly is in the closed position and two positions when the bolt assembly is in the open position. Notably, the handcocking button has the capability to pivot back and open, causing the handcocking arm to first decompress the hammer springs and then obstruct the trigger. Upon closure of the bolt assembly, the control mechanism automatically redeploys. The open position of the handcocking button enables safe positioning or decocking of the firearm. Overall, this invention eliminates constraints on the bolt assembly passage during opening and closing, positioning the handcocking button within a highly ergonomic area.

The invention relates to an anti-opening bolt assembly system utilizing the hammer springs, achieved by sliding the hammer spring rod end from a first end A to a second end B within a built-in opening of the hammer. This mechanism facilitates the forward movement of the bolt assembly, ensuring its closure following the firearm firing. The system leverages components of the percussion system without additional parts, preserving the simplicity, compactness, and reduced weight of the firearm. While no risk arises from the partial or full opening of the bolt assembly after firing, it is preferred to keep the bolt assembly closed after firing. During firing, the movement of the hammer spring guide rod end from the first end to the second end of the opening enables the hammer to apply forces to the bolt assembly, utilizing the decompression forces of the hammer springs.

A self resetting main valve assembly 103 for compressed gas partially discharges a shot plenum 117 when actuated. When actuated, compressed gas pressure within the shot plenum 117 is used to pull the main valve plunger 109 back from an outlet 150 of the shot plenum faster than a spring 111 biasing the main valve plunger toward the outlet of the shot plenum can move the main valve plunger toward the outlet of the shot plenum. The spring pushes the main valve plunger back into contact with the outlet of the shot plenum, sealing off the outlet of the main valve assembly before the user resets the trigger. When the user allows the trigger to reset, an inlet 119 of the shot plenum is unblocked such that compressed gas can flow into the shot plenum via the inlet to refill the shot plenum.

A firearm analysis device for determining the firing mode of a firearm (7) is described. The device comprises a voltage generation unit (401) that generates an alternating voltage (Ue) during the forward and / or reverse movement of a moving part of the firearm (120), a signal processing unit (410) that converts the alternating voltage into electrical energy and stores it in an energy storage device, and a signal evaluation unit (420). The signal evaluation unit remains in activated mode during two consecutive firings if it is supplied with a minimum supply voltage and switches to a non-activated mode if the supply voltage falls below the minimum. The firing mode is determined by checking whether the signal evaluation unit remains in activated mode (continuous fire) or switches to non-activated mode (single fire).The device can be integrated into firearms and enables a reliable distinction between single shots and continuous fire.

The feedback loop enables the voltage and current control to alter a voltage set point.

A trigger mechanism that can be used in AR-pattern firearms has a hammer, a trigger member, a disconnector, a locking member, and a “three position” safety selector having safe, standard semi-automatic, and forced reset semi-automatic positions. In the standard semi-automatic position, rearward movement of the bolt carrier causes rearward pivoting of the hammer such that the disconnector hook catches the hammer hook, at which time a user must manually release the trigger member to free the hammer from the disconnector to permit the hammer and trigger member to pivot to the set positions so that the user can pull the trigger member to fire the firearm. In the forced reset semi-automatic position, rearward movement of the bolt carrier causes rearward pivoting of the hammer causing the trigger member to be forced to the set position, the safety selector preventing the disconnector hook from catching the hammer hook, and thereafter when the bolt carrier reaches the substantially in-battery position the user can pull the trigger member to fire the firearm without manually releasing the trigger member. The locking member is pivotable between a first position at which the locking member mechanically blocks the trigger member from moving to the released position and a second position at which the locking member does not mechanically block the trigger member allowing the trigger member to be moved to the released position. The locking member is spring biased toward the first position and moved against the spring bias to the second position by contact from the bolt carrier during forward movement of the bolt carrier as the bolt carrier reaches a substantially in-battery position.
