Which of the following is NOT a position for carrying a handgun?

The option identified as 'Standing ready' is recognized as not being a designated position for carrying a handgun. In firearms training and handling, certain stances or holds are specifically designed for safe carry and readiness to shoot. The correct carrying positions, like the Combat tuck, Position Sul, and Firing positions, each have specific purposes in ensuring the safety of the weapon and the user.

The Combat tuck is employed when a shooter wants to keep their firearm close to their body while minimizing exposure during movement. The Position Sul is a safe carry stance where the firearm is pointed down and away from others when not in immediate use. The Firing position allows for effective targeting and control of the firearm when engaged in shooting.

In contrast, 'Standing ready' is not characterized as a formal carrying position; it suggests readiness to respond without the defined safety measures that the other positions ensure. Therefore, it stands out from the others concerning the formal methodology of firearm handling and safety.
