Punches, yes. Weapons/guns hurt but don’t seem to wound. Yes, there’s a certain level of God-mode which would probably disappoint the most experienced of guests, but I think the average guest would prefer knowing they’re not in any actual danger (I know I would, lol).
Good luck! You’re in for a treat.
So far I am enjoying it, the android management aspect is interesting, although the android (host) question sessions are becoming tedious, (how many times must they question Dolores?

), breaking the western story atmosphere which I really like, which is really good, although I realize they serve a narrative purpose in the story.
There is room to speculate as to why headquarters don’t know immediately when any host violates their set limits while acknowledging the difficulty of this. Like how would they know that Dolores swatted a bug that landed in her neck? And I find it really interesting that Stubbs (the host
clean up the mess guy) is always ready for a revolt, when he says,
there is just one line of code that prevents them from tearing us apart, prophetic indeed.
The man in black (Ed Harris) who just walks all over androids, and does not seem to experience broken immersion when he is shot multiple times, while I realize he has some sinister agenda, or maybe he is just a little nuts or obsessed with some element of how the Park works. I initially mistook him for Yul Brenner’s role, the gunslinger in the original movie. I noted at headquarters after he killed a group of androids, it was asked if he should be slowed up, it was said that he gets whatever he wants, so I assume he is a billionaire who spends a lot of time in the park. No spoilers please as if he turns out to be something else.
Which brings up a logical element that is my speculation- what happens when a guest acts like my Grandson, in Red Redemption (video game), riding into a town and starts killing everyone, just for entertainment? I would imagine in a theme park like this, it would really disrupt the stories they have laid out for guests to participate in.
At least in Red Redemption, if you go overboard, they can actually kill your character, and you suffer whatever death penalty the game puts on you, requiring a start over at an earlier save.
My point is, I would think this kind of a West World theme park would really be dependent on responsible guest behavior not to overly disrupt the environment. Maybe a control that would prevent guests to go into homicidal killing sprees for fun, but this is what, even with an agenda, seems to be what the Man in Black is doing every episode.
What if you gun down an innocent host out of the blue? Wouldn’t, shouldn’t the sheriff be allowed to take you into custody? I think it would be more immersive if guests could be subdued, without serious injury of course.
Finally, I’m was not clear how the guns work in the park. But this article clears it up a bit with spoilers, but anyone who is familiar with the original movie, not really a spoiler:
