1. A system for providing discharge monitoring of a firearm, the system comprising:
a first sensor disposed on the firearm that senses a first acceleration along a first axis and sends a first input signal;
a second sensor disposed on the firearm that senses a second environmental variable and sends a second input signal;
an event detection module that:
receives the first input signal and compares the first acceleration to an acceleration threshold indicative of a shot;
receives the second input signal and compares the second input signal to a second threshold indicative of a shot;
determines whether a discharge has occurred based on both the first signal satisfying the acceleration threshold and the second input signal satisfying the second threshold; and
generates an event detection signal based on the determination; and
a grip housing selectively coupled to the firearm and including an outer contoured body configured for receiving a hand of a user of the firearm, wherein the event detection module is received by the grip housing, the event detection module and grip housing collectively defining a grip module.
