Redhawk Extraction Issues

I have a 7 1/2" Redhawk in .45 Colt. After shooting a cylinder full of rounds, they extract out of the cylinder like butter, but when the extractor is fully pushed back the brass "sticks" in the claws (for lack of a better term) and each round must be pulled loose by hand.

In contrast, the brass in my Security Six and all my S&Ws merely fall out by themselves.

Is there an adjustment I can make?

I've had two Redhawks in .45 Colt and they have both been that way. I simply opened up the ejector star a little bit on the ones that stuck. A little emery cloth wrapped around a dowel, easy fix.

Mine did that too. A burr on the ejector star was the culprit. A little stoning cured it.
