[Sinister]

I got the gun.

Poke the knucklehead in the eye, teeth, or throat with the muzzle of your carbine.

Non compliant? FAck you, I ain't a cop, and I'm jocked up doing my job.

YOUR space dominance -- I AM THE GREAT WHITE SHARK AND I AM DOING MY JOB RIGHT HERE AND NOW.

If you truly are kinder and gentler there are some other tools (if you want to risk the sumbitch getting close enough to rassle your Carbine or pistol from you, and your buddies can't shoot him):

Pepper spray.
Stun gun.
Baton to a brachial nerve area.

But that's bullshit cop stuff.

As one of my Team Sergeants told a youngster with an M9, "Make sure that thing's well-oiled."

"Why?"

"So when the bad guy snatches it from you and jams it up your ass the front sight won't tear anything when we pull it out."
