AI summary

A firearm training system comprises a firearm training device that includes: a device body; a trigger; a trigger sensor; a laser emitter; and an electronic control system. The electronic control system has settings data stored thereon that includes one or more laser settings that defines a pulse length and/or an emission duration of the laser. The electronic control system is configured to: responsive to actuation of the trigger, control the laser emitter to emit the laser at the pulse length and/or the emission duration defined by the one or more laser settings; receive a command to change a laser setting of the one or more laser settings; and update the laser setting based on the command to vary the pulse length and/or the emission duration of the laser to be emitted by the laser emitter responsive to actuation of the trigger.
