I think using a firearm to "wound" could be construed as inhumane.
It should only be pulled from the holster to use deadly force as an absolute LAST resort. You shoot to stop a threat, you don't shoot to "wound" someone. When defending life, limb, or eyesight (and that of someone else) you don't aim at the legs or arms, you aim center mass to ensure you stop the threat. If it isn't a true threat then you don't use a firearm.
