The scene where he's sitting on the porch spinning the cylinder of his Colt .45 is just awful. How do you fit a dozen errors into 15 seconds?!? First, he's loading it. OK. Then he shuts the loading gate. Now, the barrel will not spin. Which he proceeds to do. And when he does it, looking up the business end of the gun, you see...the chambers are all empty! Magically spinning with the loaded gate closed and the hammer returned to the first cock. Really. They *actually* machined a gun to do that. Those would be the chambers on an 1873 Colt .45, and they've already told us it's 1865. I guess when your gun is from 7 years in the future, it can do really amazing things. Things the one from 7 years in the future can't. And those are just the glaring errors in that scene; there are a plethora of little ones. My nominee for the worst gun errors ever in a Spaghetti Western.
