What is M9 Weapons Condition 4?

M9 Weapons Condition 4 indicates that the weapon is in a safe and non-operational state. This condition means the chamber is empty, the magazine is also empty, and the hammer is down. This condition is essential for ensuring safety when the weapon is not in use or being handled by personnel.

Maintaining the firearm in this condition reduces the risk of accidental discharge significantly since there is no round in the chamber to fire, and the absence of a magazine further enhances its safety. Firearms training emphasizes the importance of these conditions to promote responsible handling and prevent incidents, making Condition 4 a key aspect of firearm safety protocol.
