[Terminator] I'm a T-800 model sent back from the future. What is the weakest weaponry that can destroy me?

Assuming I'm just a standard model, what's the weakest thing that can destroy my impressive metal body?

I think it’s mostly a question of what part of a Terminator would have to be damaged in order for the Terminator to be nonfunctional. So the question becomes, “What weapon could penetrate the Terminator skull and damage the chip there beyond repair?”

In the first two movies, we saw a Terminator be severed with a home made pipe bomb, limbs torn off with industrial machinery and run through with an iron bar by the strength of a T-1000. Reece’s shotgun was essentially ineffective and the police were not able to stop the T-800.  It would seem that the Terminator’s skin likely serves as some level of protection, if for no other reason than the true nature of what you would need to hit in order to damage the Terminator... the police were aiming for the body, which essentially does nothing to affect the functionality. But in Genysis, we watched someone who knew what a T-800 was destroy one with a sniper rifle. 

This is all evidence to say: If you knew what the T-800 was, a powerful hand gun, especially one with armor piercing bullets, would likely be sufficient, so long as you hit the right place.
