A method providing discharge monitoring of a firearm includes a signal processing module and a safety selector switch sensor. The event detection module has at least one sensor that senses an acceleration and generates an acceleration signal. The signal processing module receives the acceleration signal and is configured to determine whether the acceleration signal is a discharge event and generate an event detection signal based on the determination, the signal processing module further configured to maintain a shot count of the firearm based on the determination that the event detection signal is a discharge event. The safety selector switch sensor communicates with a safety switch configured on the firearm, and communicates a safety switch signal to the signal processing module corresponding to a position of the safety switch. The event detection signal is further based on the safety switch signal.

A method for determining an operational status of a firearm based on a discharge event is provided. A signal indicative of a plurality of accelerations sensed by an inertial measurement unit is received by an event detection module. A sample shot profile is determined based on the signal. The shot profile can comprise a first peak at a first time representing initial discharge of the firearm wherein a bolt of the firearm moves from an initial forward position, a second peak at a second time, representing the bolt engaging a rear buffer of the firearm, and a third peak at a third time, representing the bolt returning to the forward position. A measured bolt speed of the weapon is determined based on a difference between the second and third times. The measured bold speed is compared to a baseline weapon bolt speed. An operational status of the weapon is determined.

A system and method for recommending a corrective action based on a performance metric related to a discharge event of a firearm is provided. The method includes receiving, by a first event detection module associated with a first firearm, a plurality of first input signals over a sample window of time from a first inertial measurement unit configured on the first firearm; identifying, by the first event detection module, an occurrence of a first shot discharge of the first firearm at a shot time based on the plurality of first input signals; determining a first orientation of the first firearm at the shot time; determining a second orientation of the first firearm at a first time before the shot time; comparing the first and second orientations; determining a first performance metric related to pre-shot weapon orientation; and displaying a first recommended corrective action based on the first performance metric.
