In which hand should officers always hold their handcuffs?

Holding handcuffs in the dominant hand is strategically important for officers as it allows for greater control and efficiency when applying restraints. Officers are typically trained to handle equipment with their dominant hand because it often reflects their natural dexterity and precision. This method not only enhances the officer's ability to perform the task smoothly but also ensures that they can keep their non-dominant hand free for other necessary actions, such as maintaining physical control of the subject or protecting themselves.

Using the dominant hand allows for a more secure grip and faster reactions, which is critical in dynamic law enforcement situations. This practice reinforces the need for both safety and tactical readiness when dealing with potentially unpredictable subjects. The other options suggest holding the handcuffs in ways that could compromise the officer's effectiveness and operational safety.
