What configuration indicates that a firearm is in Condition 3?

Condition 3 for firearms generally indicates that the magazine is inserted, but the chamber is empty. This configuration allows the user to quickly load a round into the chamber from the magazine when needed while ensuring that there is no live round in the chamber, which can be safer during transport or non-operational periods.

In this scenario, having a magazine inserted but an empty chamber means that the firearm can be readied for use with minimal effort, allowing the user to maintain readiness while also prioritizing safety. This condition is commonly recognized across various firearm safety protocols.

In contrast, other configurations like having a loaded chamber or a safety disengaged might indicate greater readiness for immediate use, which does not align with the definition of Condition 3.
