Final answer:
If a firearm doesn't fire or sounds incorrect, keep it pointed in a safe direction, wait 30 seconds in case of a hangfire, carefully unload it, inspect for visible issues, and seek professional help if needed.
Step-by-step explanation:
If your firearm doesn't fire or doesn't sound right after you pull the trigger, it's important to handle the situation with caution to ensure your safety and the safety of others around you. The first thing you should do is keep the gun pointed in a safe direction, preferably downrange if you are at a shooting range.
Then, you should keep the gun on 'safe' if it has a safety, and do not touch the trigger. You should wait for around 30 seconds since some issues might be related to a 'hangfire' where there is a delay between the triggering of the primer and the gunpowder ignition.
After waiting, if the firearm is still not discharging, you should carefully unload the firearm, making sure to keep it pointed in a safe direction.
Inspect the firearm for any visible signs of damage or obstruction that might explain the misfire. If you do not have the expertise to resolve the issue yourself, or if you are uncertain about what to do next, it is crucial to seek assistance from someone trained in firearms safety or a gunsmith.
Remember, handling firearms with care and responsibility is paramount for the safety of everyone.
