Which stance emphasizes the position of the weapon arm being almost fully extended?

The modified weaver stance emphasizes the weapon arm being almost fully extended while also allowing for a stable shooting platform. This stance combines traits from the traditional weaver stance, where the shooter is turned slightly sideways to the target. The weapon arm is extended forward but not fully locked out, enabling better control and higher accuracy while allowing for a strong supporting arm position.

In contrast, the isosceles stance involves holding the firearm with both arms extended straight out towards the target, forming a triangular shape with the shooter's body. The tactical ready stance is more focused on preparedness and less on extending the weapon arm, keeping it closer to the body for quick response rather than precision aiming. The hip shooting stance, as the name suggests, involves holding the firearm at hip level, which would not include an extended position for the weapon arm, focusing instead on quick draw and point shooting.

The focus on a nearly fully extended weapon arm in the modified weaver stance provides a balance that enhances stability, control, and aim during shooting, which is crucial in defensive situations.
