I 100% agree.The ejector star is a hand fit part. An N Frame .357 part with left hand threads would be a start and then it's some careful work to make it fit your cylinder. Then you're on to making sure your original hand works with the new part.
+1 on the cleaning, or a shim or 2 for it. Shims are cheap and easy. There are different thicknesses and trial and error until you are happy.It looks to me like you may be able to solve your problems with a good scrubbing with some solvent and a brass brush. That gun is really dirty. Don't forget to clean under the star also. There's a cylinder and ejector star on ebay right now that looks very clean.
Strongly agree. From the description of not going into battery on slowly cycling, I'd more suspect a somewhat shortened hand as the problem. Ought to be easily solved with one of the oversized ones offered by Brownell's.I don't see anything wrong w/ that ratchet other than being filthy. I think if you dismantled that gun, gave it a good soaking & scrubbing inside & out it would solve most, if not all of it's issues. Possible a new hand could be needed but until everything is spotless I wouldn't bother.
