The practice barrel assembly is configured and dimensioned to replace the factory barrel of the firearm. The practice barrel assembly includes a processor, a radio transmitter, a firing pin strike sensor and a rechargeable battery. The processor is in wireless communication with an electronic device, such as a smart phone. To initiate a practice drill, the electronic device provides a start signal to the user and, simultaneously, an electronic timer is started. In response to the start signal, the user performs a practice drill that includes a dry fire of the firearm. The firing pin strike sensor detects the dry fire of the firing pin, which causes the stop of the electronic timer. The electronic device then displays the elapsed time between the start signal and the stop of the electronic timer. ## Claims ### Claim 1 A system for conducting practice drills using a firearm, the firearm having a factory barrel and a firing pin, said system comprising: a practice barrel assembly configured and dimensioned to interchangeably replace the factory barrel of the firearm; the practice barrel assembly having a barrel body; a cavity formed in the barrel body of the practice barrel assembly; a processor located within the cavity in the barrel body of the practice barrel assembly; a radio transmitter located within the cavity and in communication with the processor; and a firing pin strike sensor in communication with the processor; wherein the processor is programmed to cause the radio transmitter to transmit a wireless signal to a remote electronic device in response to the firing pin strike sensor detecting a dry fire of the firing pin. ### Claim 2 (depends on 1) The system of claim 1, wherein the barrel body comprises a weight. ### Claim 3 (depends on 1) The system of claim 1, wherein the practice barrel assembly further comprises a cap that is removably installable over the cavity. ### Claim 4 (depends on 1) The system of claim 1, further comprising a rechargeable battery disposed within the practice barrel assembly, the rechargeable battery providing power for the processor. ### Claim 5 (depends on 4) The system of claim 4, further comprising a charging port for recharging the rechargeable battery. ### Claim 6 (depends on 1) The system of claim 1, further comprising a flexible member disposed over the firing pin strike sensor. ### Claim 7 (depends on 6) The system of claim 6, where the flexible member is formed of polyurethane. ### Claim 8 An apparatus for practicing firearm training drills, said apparatus comprising: a firearm having its factory barrel replaced by a practice barrel assembly; and a processor and radio transmitter located within a cavity formed in the practice barrel assembly; wherein the processor causes the radio transmitter to transmit a signal to a remote electronic device. ### Claim 9 (depends on 8) The apparatus of claim 8, wherein the practice barrel assembly comprises a barrel body that is formed of a plastic or a polymer. ### Claim 10 (depends on 8) The apparatus of claim 8, wherein the practice barrel assembly comprises a weight to simulate the weight of the factory barrel. ### Claim 11 (depends on 8) The apparatus of claim 8, wherein the processor causes the radio transmitter to transmit a signal to the remote electronic device in response to a dry fire of the firearm. ### Claim 12 (depends on 8) The apparatus of claim 8, wherein the processor is programmed to provide an electronic timer. ### Claim 13 (depends on 8) The apparatus of claim 8, further comprising a firing pin strike sensor in communication with the processor. ### Claim 14 (depends on 8) The apparatus of claim 8, further comprising a battery to provide power to the processor. ### Claim 15 (depends on 8) The apparatus of claim 8, wherein the firearm is a pistol. ### Claim 16 (depends on 8) The apparatus of claim 8, wherein the remote electronic device is a smart phone. ### Claim 17 A method of performing firearm practice drills using a firearm, said firearm having a factory barrel for firing live ammunition, said method comprising: replacing the factory barrel of the firearm with a practice barrel assembly, the practice barrel assembly comprising a processor and a radio transmitter; performing a practice drill that includes dry firing the firearm; transmitting a radio signal from the radio transmitter to a remote electronic device in response to a dry fire of the firearm; and displaying an elapsed time for performing the practice drill on the remote electronic device. ### Claim 18 (depends on 17) The method of claim 17, further comprising causing the processor to track an elapsed time of the practice drill. ### Claim 19 (depends on 17) The method of claim 17, wherein the remote electronic device is a smart phone.
