US12416473 - Dry fire practice training device

When a semi-automatic weapon is live fired, it's firing pin is reset, and it is ready to be fired again. The shooter's hands remain in the firing position, and just the trigger finger and trigger are employed. With dry fire practice, the shooter must manually rack the slide to reset the firing pin, allowing the trigger to return to its unfired position each time a shot is simulated. This invention provides, realistic muscle memory training by duplicating the action of the trigger in normal live fire, the feel and the sound of the release of the firing pin, and the resetting of the trigger for additional trigger activation. The invention further provides components that allow use with other electronic training devices such as lasers, video simulators, and virtual reality.

The dry fire practice training device simulates the firing mechanism of a semi-automatic pistol, allowing shooters to practice trigger control without live ammunition. It incorporates a simulated ammunition magazine with a lever and microswitch that provide tactile and audible feedback, enhancing muscle memory during training.

Claim 1

A dry fire training device for use with a pistol having an ammunition magazine compartment and a trigger mechanism, the dry fire training device comprising: a simulated ammunition magazine that has opposing side portions, an exterior surface, and an interior cavity, the simulated ammunition magazine having a platform at a top end portion for operative engagement with a compression spring; a lever that is pivotably carried within the interior cavity of the simulated ammunition magazine, the lever is elongate and has a bottom end portion that is proximate an inside bottom surface of the interior cavity, and a top end portion that is proximate the top end portion of the simulated ammunition magazine, the lever further having a projection at the top end portion thereof that operatively communicates with the trigger mechanism of the pistol, and a projection for engagement with the compression spring, and the lever is pivotably movable on a fulcrum between a resting position and a firing position, the fulcrum is sandwiched between the opposing side portions inside the interior cavity of the simulated ammunition magazine; a detent reed carried on the lever, the detent reed formed of a material that generates a tactile and audible signal when manipulated through an activation point between an un-tripped position and a tripped position; a microswitch operatively connecting the lever to the simulated ammunition magazine such that the microswitch is activated when the lever is pivotably moved on the fulcrum from the resting position to the firing position; and a microprocessor operatively communicating with the microswitch and which sends a signal when the microswitch is activated. a simulated ammunition magazine that has opposing side portions, an exterior surface, and an interior cavity, the simulated ammunition magazine having a platform at a top end portion for operative engagement with a compression spring; a lever that is pivotably carried within the interior cavity of the simulated ammunition magazine, the lever is elongate and has a bottom end portion that is proximate an inside bottom surface of the interior cavity, and a top end portion that is proximate the top end portion of the simulated ammunition magazine, the lever further having a projection at the top end portion thereof that operatively communicates with the trigger mechanism of the pistol, and a projection for engagement with the compression spring, and the lever is pivotably movable on a fulcrum between a resting position and a firing position, the fulcrum is sandwiched between the opposing side portions inside the interior cavity of the simulated ammunition magazine; a detent reed carried on the lever, the detent reed formed of a material that generates a tactile and audible signal when manipulated through an activation point between an un-tripped position and a tripped position; a microswitch operatively connecting the lever to the simulated ammunition magazine such that the microswitch is activated when the lever is pivotably moved on the fulcrum from the resting position to the firing position; and a microprocessor operatively communicating with the microswitch and which sends a signal when the microswitch is activated.
