One of my . 45 Vaqueros just stopped working. Mid dry fire. Cylinder won't turn, hammer won't cock. I switched cylinders with another Vaquero and then that one wouldn't work. The common problem is the cylinder. It won't work in any of my other Vaqueros. You just can't break a Ruger cylinder, but that's the common bad part. What could possibly be wrong? How can I fix it or do I have to send it back to Ruger?

Almost every cylinder needs to be fitted to a frame. They are rarely interchangeable. Sounds like you may have a broken spring.
