Endshake is a pretty common problem in well used revolvers.
This S&W Model 67-1 that came in for some troubleshooting. The customer could only get a couple cylinders shot before the gun would lock up.
The barrel-cylinder gap was out of spec and the cylinder was hitting the forcing cone. Classic case of cylinder endshake.
After verifying yoke alignment, I added an endshake bearing and straightened the ejector rod. Good to go! Shoots like a dream now.
