When you suspect a live round is chambered and you cannot confirm safety, the correct approach is to treat the weapon as loaded and clear it using established procedures, while seeking range safety guidance. This follows the fundamental safety principle that a firearm must be treated as if loaded at all times. By pausing, maintaining the muzzle in a safe direction, and performing the prescribed clearing steps under supervision (often with a Range Safety Officer present), you remove any live round from the chamber and prevent an accidental discharge. This keeps everyone on the range safe and ensures the weapon is handled only under controlled conditions. Ignoring the situation can lead to an unintentional discharge. Disassembling on the range without proper procedures and oversight introduces new hazards and violates range safety rules. Firing a round to test safety is not an allowed or safe method; it creates a real danger to nearby personnel and equipment and defeats the purpose of careful, controlled clearing.
