Which action should be taken if a gun fails to fire immediately?

The appropriate action to take if a gun fails to fire immediately is to wait a moment and then check. This is known as a "hang fire," where the cartridge may ignite after an unexpected delay. Waiting for a brief period (usually around 30 seconds) allows time for any potential hang fire to discharge safely, minimizing the risk of injury. After this waiting period, it is then safe to proceed with further inspection of the firearm.

Taking immediate action, such as removing the magazine or calling for assistance, may not allow for the possibility that the round could discharge on its own. Unloading and cleaning the firearm is also not advisable until it is determined that there is no danger of a hang fire. Learning to recognize and respond appropriately to a failure to fire is an essential safety protocol for firearm handling.
