^^^ to the above, that indicates a bad cylinder out of the machine shop at the manufacturers. Hmm.. if you say you have seen it... well... OK. I believe you.
Many times in shipping and handgling the barrel wedge can get jammed too tight and cause cylinder lock up. It can also happen to a newbie that pushes it too hard. Takes a little practice to know how tight to push the wedge in.
What this indicates is an arbor that is too short. If the arbor is the correct length you can push on the wedge all you like and the cylinder to forcing cone gap will stay the same. As you push the wedge in further and further you are literally bending the frame up and up... the pistol shoots higher and higher.. and then the cylinder will jam against the forcing cone and lock it up.
