A system and method for determining a performance metric based on a discharge event of a firearm includes a first inertial measurement unit (IMU) and a first event detection module. The first IMU is disposed on a first firearm and senses movement including at least one of accelerations and rotations. The first event detection module can receive a plurality of first input signals from the first IMU indicative of the movement. The first event detection module can identify an occurrence of a first shot discharge of the first firearm at a shot time based on the plurality of first input signals; determine a first orientation of the first firearm at the shot time; determine a second orientation of the first firearm at a first time before the shot time; compare the first and second orientations; and assign a first stability index based on the first and second orientations.
