APOSTC Firearms Practice Test

Focus on how each type of discharge starts. A negligent discharge happens when the shooter handles the firearm unsafely or violates safety rules, leading to an unintended discharge. An accidental discharge occurs even with proper handling, due to a mechanical failure inside the firearm. A misfire means the cartridge did not ignite at all, so no discharge occurs (there can be a delay, but the round fails to fire). This makes the best description the one that states: negligent discharge results from unsafe handling or safety-rule violations; accidental discharge is due to mechanical failure despite proper handling; misfire is a failure to ignite a cartridge. The other descriptions mix up these distinctions (for example, treating misfire as normal ignition or as the bullet leaving the barrel, or claiming negligent and accidental are the same), which isn’t accurate.
