Abstract: A firearm malfunction training device and method include a blank malfunction round that simulates a T3 malfunction and allows a realistic clearing protocol during the training. The malfunction round size and shape generally mimic the corresponding live round, so that malfunction round moves like the live round through the magazine. However, the malfunction round has a front end/portion that is oversized in diameter and does not fit properly or fully through the firearm breech, to jam the firearm loading mechanism at the breech. Preferably, the malfunction round also has a conical rear region radially-undersized relative to the live round casing, whereby the malfunction round leaves the magazine when the magazine is stripped from the firearm to start the clearing protocol. The enlarged front end and undersized rear region effectively simulate, and provide a realistic protocol for identifying, clearing and, correcting, a T3 malfunction.
