A slap fight is one thing. A kick to the head raises the escalation of force up a notch, as that can easily kill a person. There would be a firm, "Get the fu ck on the ground, NOW!" followed by "I will shoot you." If they take a step, drop the hammer, acquire next target, choose next action based on the remaining person's actions. Screw the physical altercation where they may get ahold of my weapon.

If I am anywhere with my kids and that happens, duck. I've drawn twice, once as a civilian, once as a deputy. Both times I've been part way through my trigger pull when they complied. No issues.
