The ejector housing attaches to the side of the barrel. Check to see that the barrel hasn't turned slightly causing the missalignment your describing. I don't know for sure, just guessing here. I have had pistols in the past that the barrel turned under heavy recoil. Never in a 357 but in a couple of 44mags. Also check the ejector housing to see if it's come loose, I've blown these off a time or two also. KN
