Cylinder doesn't spin at half cock
Hey guys, just bought a pietta '51 navy colt today. Brought it home, took it apart and cleaned it up. Now the problem is the cylinder doesn't spin freely at half cock. I can rotate it as far as the next nipple (1/12 of cylinder turn) but then it locks up like at full cock. It was working fine in the store and for a while after I cleaned it, but now its not. Anybody know how to solve this?
