The shooter's hands remain in the firing position, and just the trigger finger and trigger are employed. But with dry fire practice, the shooter must remove a hand from the weapon and ratchet the slide to reset the firing pin, allowing the trigger to return to its unfired position. This must be done each time a shot is simulated. This invention provides, by incorporating a modified ammunition magazine in the weapon's magazine compartment, realistic muscle memory training by duplicating the action of the trigger, the feel and the sound of the release of the firing pin and the resetting of the trigger for additional trigger activations. It does not interact with the weapon's firing pin and does not require any alterations to the weapon such as disassembling and reassembling of parts. ## Claims ### Claim 1 A dry fire practice-training device utilizing the weapon's empty magazine compartment, said training device comprised of: a modified ammunition magazine acting as an encasement for the device's other components, said components being: a lever providing a means for interaction between the weapon's trigger mechanism and a doubled detent reed; an adjusting assembly providing for the regulated activation of said detent reed; a compression spring providing a forward force to return said lever to its initial resting position; a sliding member, providing for the positioning of said detent reed bearing lever behind the said weapon's trigger mechanism when the said device is inserted into the said weapon's empty magazine compartment; and an orange base plate providing for the alignment of the said sliding member and for the recognition that the weapon is in a safe training mode; whereby the said dry fire practice-training device provides audible and tactile simulation for realistic, repetitive dry fire training. ### Claim 2 (depends on 1) The dry fire training device of claim 1, comprised of a mechanism whereby the said weapon's empty magazine compartment is utilized to provide a means for the said device to provide audible and tactile simulation for realistic, repetitive dry fire training, and the resetting of the said weapon's trigger mechanism for multiple activations. ### Claim 3 (depends on 1) The dry fire training device of claim 1, comprised of a said modified ammunition magazine acting as an encasement for the said device's other components, and providing for an interface between the said device and the said weapon's trigger mechanism. ### Claim 4 (depends on 1) The dry fire training device of claim 1, comprised of a said ammunition magazine that has been altered by three holes: one to receive the fulcrum pin for the said detent reed bearing lever, a larger hole to allow the sound from the said detent reeds to be heard better by the shooter, and another larger hole to provide access to the said detent reed's regulating assembly. ### Claim 5 (depends on 1) The dry fire training device of claim 1, comprised of a said ammunition magazine that has been altered with a said regulating assembly comprised of a set screw in a nylon lock nut adhered to said magazine's inside back surface which allows the said detent reeds to be adjusted to activate at the position when the said trigger mechanism would release the said weapon's firing pin during normal live fire. ### Claim 6 (depends on 1) The dry fire training device of claim 1, comprised of a lever providing a member for the interaction between the said weapon's trigger mechanism and a said doubled detent reed, said lever being fabricated from a channel material of proper dimensions for the support of said detent reeds, and providing a platform for a compression spring. ### Claim 7 (depends on 6) The dry fire training device of claim 6, comprised of a said lever fabricated of a length of channel material with: a slot to support a said doubled detent reed, providing audible and tactile simulation for repetitive trigger action; a hole for a machine screw and nut to retain said doubled detent reeds in said slot; a platform for a compression spring which returns the said lever to its resting position thereby resetting the said weapon's trigger mechanism for multiple activations; a hole for a fulcrum pin for said lever to rotate upon; and an elongated member that intercepts the said weapon's trigger mechanism. ### Claim 8 (depends on 7) The dry fire training device of claim 7, comprised of a lever of a length of channel material fabricated to support a compression spring between a platform of the said lever and the back wall of the said ammunition magazine which when compressed, returns the said lever to its resting position, thereby allowing for the intermediate reset of the said trigger mechanism for multiple trigger activations or when the trigger is completely released, allows the trigger to return to its unfired, resting position. ### Claim 9 (depends on 1) The dry fire training device of claim 1, comprised of a sliding member, providing for the positioning of said lever behind the said weapon's trigger mechanism when the said device is inserted into the said weapon's empty magazine compartment. ### Claim 10 (depends on 8) The dry fire training device of claim 8, comprised of a said sliding member which has an angled surface providing an interaction between the said lever and the inner front surface of the said ammunition magazine to retract the said lever toward the back of the said magazine far enough to be positioned behind the said trigger mechanism when the said device is inserted into the said empty magazine compartment. ### Claim 11 (depends on 8, 9) The dry fire training device of claim 8, comprised of said sliding member which has a bent projection on the opposite end of the said angled surfaced end which extends through the base plate and receives the upward force of the shooters hand when the said device is inserted into the said weapon's empty magazine compartment thus producing the sliding motion to accomplish the action of claim 9 ### Claim 12 (depends on 1, 9, 10) The dry fire training device of claim 1, comprised of a said base plate altered with a slot to provide for the alignment of the said bent projection of claim 10 to extend through said base plate to receive the activating force of the shooter's hand to accomplish the action of claim 9. ### Claim 13 (depends on 11) The dry fire training device of claim 11, comprised of a said base plate of an orange color to indicate to the shooter and others that the said weapon has a safe, non-live ammunition magazine inserted.
