[Fiction]Could a bullet from a authentic 1875 Colt Single Action Army Revolver pierce a giant scorpion the size of a lion?

Well the title says it all. I have a writing problem where I don't like breaking physics in my story's and I have a MC who is looking at having to fight it. Is it a lost cause or is he gonna have to leg it? For frame of refernces the carapace is likely 1ish inches thick.

When it comes to breaking physics, the existence of a scorpion that size is a major issue.

One of the long-standing reasons suggested for arthropods not reaching that kind of size is that an exoskeleton scaled up similarly to the size itself would be too heavy for the creature to move. This has been dismissed more recently, since there is no reason that the exoskeleton would be relatively as thick. There are still other issues though, relating to mechanical effectiveness of the leg structure, and lung efficiency (ruling out insects, which rely on oxygen diffusion, but with more doubt about the simple lungs that scorpions have).

So, the upshot is that either the scorpion would be too heavy to move, or else it would have a relatively thin chitin exoskeleton, which would present little difficulty to a revolver like this.
