Customer brought in S&W 25-5 with wear through the bluing at rear of cylinder. The gun appears to be operating OK, but when the cylinder is opened, it is possible for rear of cylinder to touch the gun frame at the rear edge of the cylinder. There is a corresponding wear spot on the frame at that spot. If the revolver is held horizontally with the cylinder hanging down, it appears that the cylinder is parallel to the frame. But, the cylinder does have some side play on its center pin which allows it to touch the frame at the rear of the cylinder. What is the problem with this revolver, and how do I fix it?
It sounds as though the cylinder is rubbing the frame lug. Make sure the frame lug is not loose and protruding to a position that rubs the side of the cylinder. They are staked from the inside. If it is tight a small amount of material may be removed where the stud rubs the cylinder. Be aware the frame stud is what keeps the cylinder on the yoke when the cylinder is open. Ken

Thanks for the response. The cylinder is not contacting the frame stud. It is touching the frame in front of the stud. However, after disassembling the revolver, I can see that the crane is bent. Thanks again.
