Thanks to all. Basically when you pull the trigger or cock the hammer the cylinder just sits there. To expand on my first post. Originally the gun would wok fine for sever firings, both DA and SA then, one or twice per cylinder it would not rotate. If you tried cocking it several time eventually it would catch and the cylinder would rotate and lock up just fine.

After I took it apart and put it back together it's like the hand isnc't moving at all. I didn't see any broken parts and nothing fell out during the disassembley so I figured something was either gummed up or had come loose and when I put it back together I left something off a stud or spring or something. I'll take the side plate off in the near future and take a couple of pics and post them. Maybe someone can see the problem.

Thanks again for the replies.
