Here's my wacky theory

Spoiler!

re-the guns and bullets. I believe they are real. I believe that when guests come to Westworld, they are sold or rented guns and clothing in a gift shop, and those items have some kind of personal shield. I would think that the guests would want the actual realism and thrill of shooting a real gun. But because of the personal shields humans can't kill each other and robots can't kill them.

Ok, my main theory.

The Gunslinger is a robot, and one of the first realistic builds by Anthony Hopkins, and he's been around since near the start of the park, and long before most of the current employees. At some point, as we've seen with Hopkins, he made the Gunslinger nearly perfectly human and as such self aware. He began to believe himself to be human or better then human, or had a melt down like the father and was boxed. But somehow he reactivated himself and escaped.

At some point, the Gunslinger forgot he was a droid, or programmed himself to be human, and because of that he overcame his programming and began to act human, and also, if my above theory is right, he stole the tech to shield himself. So at that point he could kill robots.

Because all of the employees came on board after this rebellion by the gun slinger, they don't realize that he's a robot, they think he's an especially vile and homicidal human.

But the gunslinger never leaves the park, he just goes into the badlands and hides.

The next logical question, is can the gunslinger kill a human? I have my doubts if the protection is actually worn by the humans and is not some programmed individual shield (if they are using real guns and real bullets). But that might be what his quest is or what he's searching for. He's either looking for the humans that run the park, or he's looking at a way to shut down the protective tech so he can kill everyone.

Just my 2 cents
