What should be done while handling the M9 concerning its trigger?

Keeping your finger straight and off the trigger until you are ready to fire is a fundamental safety practice in firearm handling. This principle is crucial to prevent unintentional discharges, which can occur if your finger is inadvertently placed on the trigger while the firearm is being handled. By maintaining this discipline, you ensure that the firearm remains safe until the moment you complete your target acquisition and are prepared to engage.

This practice aligns with key firearm safety rules, which emphasize the importance of treating every weapon as if it is loaded and maintaining control over your trigger finger. It helps reinforce good habits among users, contributing to overall safety in handling firearms.

In contrast, other options, such as keeping your finger on the trigger at all times, would greatly increase the risk of accidental discharge. Testing the trigger frequently could lead to unsafe conditions, particularly in non-operational settings. Ignoring the trigger altogether until aiming may cause delays or result in poor handling practices, as it is essential to maintain awareness of all aspects of firearm control during handling. This understanding highlights the importance of the correct approach to trigger management in firearm safety.
