What condition must the weapon be in before proceeding with loading?

Before loading the M9 service pistol, it is essential for the weapon to be in Condition 4. This condition refers to the pistol being unloaded, with no magazine inserted and the chamber clear of any ammunition. Ensuring that the firearm is in this state is crucial for safety, preventing accidental discharges during the loading process.

Once the weapon is confirmed to be in Condition 4, it can be safely handled for loading. This procedure aligns with standard safety protocols that emphasize checking for ammunition presence before any handling takes place. It is a fundamental principle in firearm safety training to maintain awareness of the condition of the weapon at all times.
