Abstract: A firearm training system includes a firearm, a sensor, a data processor, and a display. The sensor measures and records the motion of the firearm before, during, and after the firearm is shot. In some embodiments, the sensor is located on the firearm. The sensor communicates with the data processor. In some instances this communication is conducted wirelessly. Data regarding the movement of the firearm is analyzed via the data processor and trends are determined. These trends are then correlated with shooting technique deficiencies which can be communicated to a user via the display. In some embodiments, the data processor and display are a single computing device, such as a tablet, smartphone, or laptop.
