1. A method for determining an operational status of a firearm based on a discharge event, the method comprising:
measuring a first acceleration on the firearm at a first time;
measuring a second acceleration on the firearm at a second time;
calculating a measured shot separation of first and second accelerations between the first and second times;
comparing the measured shot separation to at least one shot separation threshold;
assigning a speed of a movement member in the firearm based on the comparing;
determining the operational status of the firearm based on the assigned speed; and
communicating the operational status to a first user of the firearm in real-time.
